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.

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.
