Revision 1.2 Page 3 ® ® 2.3 Mounting the ACM100 Attach the ACM100 securely to the vessel usi ng 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.
ACM100 User’s Manual Figure 2 – NMEA 2000 ® Connector Face Views 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 det aching the splash guard from the unit.
® ® WARNING: If the supplied current transformer is plac ed around a wire carrying AC current, then extremely high voltages can develop on the output leads of the current transformer, with severe risk of el ectrocution.
ACM100 User’s Manual a. Connect the black wire to pin 7 (I A+ ) on the ACM100 b. Connect the white wire to pin 8 (I A- ) on the ACM100 c. Disconnect the hot wire from the AC power source and plac e it through the hole in the Current Sensor such that the arrow on the Current Sensor points towards the AC power source.
