AC power source. Then, reattach the hot wire to the AC source. Step 3: You must supply a cable for connecting the voltage sense pins on the ACM100 to the AC source. For the purposes of these instructions, we will assume that the cable has one black conductor and one white conductor. - Page 11 AC power source. Then, reattach the hot wire to the AC power source. Step 4: You must supply cables for connecting the voltage sense pins on the ACM100 to the AC source. For the purposes of these instructions, we will assume that each cable has one black conductor and one white conductor.

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. -
Page 18: Restore Factory Defaults
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). -
Page 19: Output Parameters
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. -
Page 20: Maintenance
Clean the unit with a soft cloth. Do not use chemical cleaners as they may remove paint or markings or may corrode the ACM100 enclosure or seals. Do not use any cleaners containing acetone, as they will deteriorate the plastic enclosure. -
