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.
Revision 1.2 Page 7 ® ® will need to purchase an optional cu rrent sensor (Part # M000630) fo r monitoring this type of system. Step 1: De-energize the AC Source. Step 2: The Current Transformer has black and wh ite wires. Install the Phase A Current Transformer as follows: a.
ACM100 User’s Manual 2.4.2.3 Three-Phase (Phase A, B, C) Connection Please refer to Figure 5 for connecting the ACM100 to a three phase system. Page 8 Revision 1.
Revision 1.2 Page 9 ® ® c. Disconnect the Phase B hot wire from the AC power sour ce and pl ace it through the hole in the Current Sensor such that the arrow on t he Current Sensor points towards the AC power source. Then, reattach the Phase B hot wire to the AC power source.
ACM100 User’s Manual Page 10 Revision 1.2 c. Connect the black wire from one end of the second Voltage Sense cable to pin 3 (V CLine ) on the ACM100 d. Connect the black wire from the other end of the second Voltage Sense cable to a fuse appropriately sized for the black wire (18 gauge wire minimum and 3 amp fuse or less).
Revision 1.2 Page 11 ® ® 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: • Si.
ACM100 User’s Manual Page 12 Revision 1.2 reconnecting the current transformer, you may c hange the value of this parameter from the default value of “Normal Install” to “I nverse Install” to correct for this.
