2 Installation
2.1 Unpacking the Box
When unpacking the box containing the Maretron ACM100, you should find the following items:
1 – ACM100 – AC Monitor
1 – 100A AC Current Transducer with 5 ft. (1.5m) long cable (Part # M000630)
1 – Parts Bag containing 4 Stainless Steel Mounting Screws
1 – ACM100 User’s Manual
1 – Warranty Registration Card
If any of these items are missing or damaged, please contact Maretron.
2.2 Choosing a Mounting Location
Please consider the following when choosing a mounting location.
- The ACM100 is waterproof, so it can be mounted in a damp or dry location.
- The orientation is not important, so the ACM100 can be mounted on a horizontal deck, vertical bulkhead, or upside down if desired.
- The ACM100 is temperature rated to 55°C (130°F), so it should be mounted away from engines or engine rooms where the operating temperature exceeds the specified limit.
2.3 Mounting the ACM100
Attach the ACM100 securely to the vessel using the included stainless steel mounting screws or other fasteners as shown in Figure 1 below. Do not use threadlocking compounds containing methacrylate ester, such as Loctite Red (271), as they will cause stress cracking of the plastic enclosure.
Figure 1 – Mounting the ACM100
2.4 Connecting the ACM100
The ACM100 requires two types of electrical connections: 1) the NMEA 2000® connection (refer to Section 2.4.1), and 2) the AC sensor connections (i.e., current transducer(s) and sensing voltage(s) connections), which are described in Section 2.4.2.
2.4.1 NMEA 2000® Connection
The NMEA 2000® connector can be found on the side of the enclosure. The NMEA 2000® connector is a round five pin male connector (see Figure 2). You connect the ACM100 to an NMEA 2000® network using a Maretron NMEA 2000® cable (or compatible cable) by connecting the female end of the cable to the ACM100 (note the key on the male connector and keyway on the female connector). Be sure the cable is connected securely and that the collar on the cable connector is tightened firmly. Connect the other end of the cable (male) to the NMEA 2000® network in the same manner. The ACM100 is designed such that you can plug or unplug it from an NMEA 2000® network while the power to the network is connected or disconnected. Please follow recommended practices for installing NMEA 2000® network products.

2.4.2 AC Sensor Connections
The ACM100 sensor connections are made by connecting to the 12-pin terminal strip on the top of the unit. First, remove the four screws at the corners of the unit detaching the splash guard from the unit. On the bottom of the splash guard, you will find a label detailing the wire connection to pin number assignments, which are repeated in the table below.

WARNING: The voltages present on AC circuits can cause electrocution. Before making any electrical connections to the ACM100, ensure that power is removed from all AC circuits that will be connected to the ACM100. Only restore AC power after all connections have been made to the ACM100 and the splash guard has been re-installed. |
|
|
WARNING: If the supplied current transducer is placed around a wire carrying AC current, then extremely high voltages can develop on the output leads of the current transducer, with severe risk of electrocution. For safety, keep the output leads of the current transducer(s) shorted or tied together until they are connected to the proper terminals on the ACM100. |
|
|
WARNING: User supplied voltage sense cables must be 18 gauge or larger, have insulation rated to 600V, and must have the conductor connected to the hot lead of the AC power source protected by a fuse rated at 3A or less (the current consumed by the voltage sense circuit on the ACM100 is negligible, at less than 10mA). |
Before attempting to connect the ACM100 to the AC source, determine the type of system you will be monitoring. The ACM100 supports the connection and monitoring of four different system types; 1) single-phase single line system (Section 2.4.2.1), 2) single-phase dual line system (Section 2.4.2.2), 3) three-phase wye connected system (Section 2.4.2.3), or 4) three-phase delta connected system (Section 2.4.2.4).

2.4.2.4 Three-Phase Delta (Phase A, B, C) Connection
Please refer to Figure 6 for connecting the ACM100 to a three phase delta system.
Figure 6 – Three-Phase Delta Connection Diagram
Use the following instructions when you are connecting the ACM100 to a three-phase delta circuit connected via three hot wires. You will need to install three current transducers and three user-supplied voltage sense cables. The ACM100 comes with a single current transducer so you will need to purchase two optional current transducers (please refer to Section 1.3) for monitoring this type of system.
Step 1: De-energize the AC Source.
Step 2: The Current Transducer has black and white wires. Install the first Current Transducer as follows:
a. Connect the black wire to pin 7 (IA+) on the ACM100
b. Connect the white wire to pin 8 (IA-) on the ACM100

Step 8: Connect the neutral terminals as follows:
a. Connect a white wire between pin 4 (VANeutral), pin 5 (VBNeutral), and pin 6 (VCNeutral) on the ACM100. This creates a “floating neutral” signal that will enable measurements to be made without a true neutral connection.
2.4.3 Checking Connections
Once the NMEA 2000® connection, Current Transducer(s), and Voltage Sense connection(s) to the ACM100 have been completed, restore power to the monitored AC source and check to see that information is being properly transmitted by observing an appropriate NMEA 2000® display. If you don’t see AC power data, refer to Section 5, “Troubleshooting”.
2.5 Configuring the ACM100
The ACM100 will transmit data over the NMEA 2000 network as it is shipped from the factory; however, it may require configuration, depending on the type of AC source being monitored. There are several configurable items within the ACM100, which are detailed in the remainder of this section.
You configure the ACM100 using Maretron N2KAnalyzer® software or a Maretron DSM150/DSM250 display. Please refer to the N2KAnalyzer User’s Manual, DSM150 User’s Manual, or DSM250 User’s Manual, as appropriate, for details.
2.5.1 Advanced Configuration…
Certain parameters do not normally need to be set in order for normal operation, but are included in an advanced configuration section for use in special situations.
2.5.1.1 Current Transducer A
There are two configurable items for Current Transducer A: amperage and direction.
If you are using the 100A current transducer (P/N #M000630), select the 100A option. If you are using the 400A current transducer (P/N #M000612), select the 400A option.
For the direction setting, if you notice that the current of phase A is negative when it should be positive, or vice-versa, then the current transducer has been installed backwards. If this happens, then instead of reconnecting the current transducer, you may change the value of this parameter from the default value of “Normal Install” to “Inverse Install” to correct for this.
2.5.1.2 Current Transducer B
There are two configurable items for Current Transducer B: amperage and direction.
If you are using the 100A current transducer (P/N #M000630), select the 100A option. If you are using the 400A current transducer (P/N #M000612), select the 400A option.
For the direction setting, if you notice that the current of phase B is negative when it should be positive, or vice-versa, then the current transducer has been installed backwards. If this happens, then instead of reconnecting the current transducer, you may change the value of this parameter from the default value of “Normal Install” to “Inverse Install” to correct for this.
2.5.1.3 Current Transducer C
There are two configurable items for Current Transducer A: amperage and direction.
If you are using the 100A current transducer (P/N #M000630), select the 100A option. If you are using the 400A current transducer (P/N #M000612), select the 400A option.
For the direction setting, if you notice that the current of phase C is negative when it should be positive, or vice-versa, then the current transducer has been installed backwards. If this happens, then instead of reconnecting the current transducer, you may change the value of this parameter from the default value of “Normal Install” to “Inverse Install” to correct for this.
2.5.1.4 Power Damping Period
If you feel that the monitored Power parameters are changing too quickly or too slowly on the display, you can adjust the damping that is applied to the output readings by adjusting this parameter. . The default damping period is 5 seconds. . You may change it to a value in the range of 0.2 seconds to 10 seconds.
2.5.1.5 V,I,F Damping Period
If you feel that the monitored Voltage, Current, and Frequency parameters are changing too quickly or too slowly on the display, you can adjust the damping that is applied to the output readings by adjusting this parameter. . The default damping period is 0.5 seconds. . You may change it to a value in the range of 0.2 seconds to 10 seconds.
2.5.1.6 Installation Description
You can configure the two installation description parameters with any text you wish. Examples include date of installation, location, etc. NMEA 2000 diagnostic tools such as Maretron N2KAnalyzer® can display this information.
2.5.1.7 NMEA 2000® PGN Enable/Disable
The ACM100 is capable of transmitting many different kinds of NMEA 2000® messages (or PGNs) associated with AC power sources. You may individually enable or disable each of these messages. You may also change the rate of transmission of each of these messages if desired.
2.5.1.8 Restore Factory Defaults
Selecting this configuration option causes all stored parameters in the ACM100 to be reset to the values they contained when the unit was manufactured.
2.5.2 AC Circuit Type
You must configure the ACM100 as to what type of AC circuit connection it is monitoring. The allowable values for this parameter are as follows:
- Single-Phase (Phase A) – use this value when power is connected via a single hot wire and a single neutral wire (a typical 110VAC connection in the US).
- Single-Phase (Phase A, B) – use this value when power is connected via the two hot wires and single neutral wire from a single phase of a transducer (a typical 220VAC connection in the US).
- Three-Phase (Phase A, B, C) – use this value when power is connected via the three hot wires and single neutral wire from a three-phase “Wye” or “Delta” connected circuit.
2.5.3 AC Device Type
You must configure the ACM100 as to what type of AC source it is monitoring. The allowable values for this parameter are as follows:
- “Generator” (default) – use this value when you are monitoring the output of a genset.
- “Utility” – use this value when you are monitoring shore power
- “Bus” – use this value if you are monitoring power flowing across a cable that is not located directly at the output of a genset or a shore power connection (e.g., an AC selection switch might have as an input the shore power and another input from the genset, connecting the ACM100 at the output of the AC selection switch would require the ACM100 to be configured as “Bus”.
2.5.4 Device Instance
NMEA 2000® provides a unique AC power instance for each AC power source on a vessel. This value should be programmed in each ACM100 so that each ACM100 is associated with a unique device instance number. The default instance number is 0, which is used to indicate the first ACM100 that is hooked to the network. Subsequent ACM100s connected to the network would be numbered 1, 2, and so on.
2.5.5 Label
Program this parameter with a text string which identifies this device. Maretron display products will display this label text when you are selecting data to display.
Reset Total Energy RecordedThe ACM100 accumulates the total energy imported from a Utility and exported from a generator. Select this option to zero the total energy accumulated readings in the ACM100.
3 Output Parameters
The ACM100 outputs a variety of information about the AC power source onto the NMEA 2000 network. The tables below detail which measurements are made available on the bus for the different combinations of different AC source types and circuit types which may be selected.
