1 Introduction
Congratulations on your purchase of the Maretron Alternating Current (AC) Monitor (ACM100).
Maretron has designed and built your ACM100 to the highest standards for years of
dependable and accurate service.
Maretron’s ACM100 is a device which monitors AC power sources and outputs information
about these sources onto the industry standard NMEA 2000® marine data network. ACM100
output information is then displayed with networked NMEA 2000® equipment such as the
Maretron DSM250 dedicated display or with NMEA 2000® compatible software such as
Maretron N2KView.
The Maretron ACM100 is designed to operate within the harsh demands of the marine
environment. However, no piece of marine electronic equipment can function properly unless
installed, configured, and maintained in the correct manner. Please read carefully and follow
these instructions for installation, configuration, and usage of the Maretron ACM100 in order to

2.1 Unpacking the Box
When unpacking the box containing the Maretron ACM100, you should find the following
items:
1 – ACM100 – AC Monitor
1 – AC Current Sensor with 5 ft. (1.5m) long cable (Part # PCT-1000-101-03)
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.
1. The ACM100 is waterproof, so it can be mounted in a damp or dry location.
2. The orientation is not important, so the ACM100 can be mounted on a horizontal deck,
vertical bulkhead, or upside down if desired.
3. 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.
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 sensor(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.

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 transformer is placed around a wire carrying
AC current, then extremely high voltages can develop on the output leads of the
current transformer, with severe risk of electrocution. For safety, keep the output
leads of the current transformer(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 three different
system types; 1) single-phase single line system (Section 2.4.2.1), or 2) single-phase dual line
system (Section 2.4.2.2), or 3) three-phase system (Section 2.4.2.3).

Figure 5 – Three-Phase Connection Diagram
Use the following instructions when you are connecting the ACM100 to a three-phase “Wye”
circuit connected via three hot wires and a single neutral (NOTE: Three-phase delta connected
circuits are not supported by the ACM100). You will need to install three current transformers
and three user-supplied voltage sense cables. The ACM100 comes with a single current
transformer so you will need to purchase two optional current sensors (Part # PCT-1000-10103) for monitoring this type of system.
Step 1: De-energize the AC Source.
Step 2: The Current Transformer has black and white wires. Install the first Current
Transformer as follows:

placed within 6 inches of the connection to the hot wire).
2.4.3 Checking Connections
Once the NMEA 2000® connection, Current Sensor(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 a Maretron DSM250 display or other NMEA 2000® display
unit that is capable of configuring the ACM100. Please refer to the Maretron DSM250 User’s
Manual for details.
2.5.1 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.
2.5.2 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”.
Page 10
Revision 1.0
®
2.5.3 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 transformer (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” connected circuit.
2.5.4 Reset Total Energy Recorded
The 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.
2.5.5 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.
2.5.5.1 Device Priority
If you have only one ACM100 on a particular AC power source, you should leave the priority
selection at the default value of 0. However, NMEA 2000® can provide a unique priority for
allowing multiple, redundant sensors for a single AC power source on a vessel. Redundant
sensors for a single AC power source should have the same device instance number and
different priority selections. If you have redundant sensors on a single AC power source, you
should leave the primary sensor at its default priority value of 0, and program the secondary
sensor with a priority value of 1.
2.5.5.2 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.
2.5.5.3 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.
2.5.5.4 Current Transformer A
If you notice that the current of phase A is negative when it should be positive, or vice-versa,
then the current transformer has been installed backwards. If this happens, then instead of
Revision 1.0
Page 11
ACM100 User’s Manual
reconnecting the current transformer, you may change the value of this parameter from the
default value of “Normal Install” to “Inverse Install” to correct for this.
2.5.5.5 Current Transformer B
If you notice that the current of phase B is negative when it should be positive, or vice-versa,
then the current transformer has been installed backwards. If this happens, then instead of
reconnecting the current transformer, you may change the value of this parameter from the
default value of “Normal Install” to “Inverse Install” to correct for this.
2.5.5.6 Current Transformer C
If you notice that the current of phase C is negative when it should be positive, or vice-versa,
then the current transformer has been installed backwards. If this happens, then instead of
reconnecting the current transformer, you may change the value of this parameter from the
default value of “Normal Install” to “Inverse Install” to correct for this.
2.5.6 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.
2.5.7 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.
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.
