ACM100 User's Manual
a. Connect the black wire from one end of the second Voltage Sense cable to pin 3
(V
) on the ACM100
CLine
b. 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).
c. Connect the other end of the fuse to the AC source hot wire (the fuse should be placed
within 6 inches of the connection to the hot wire).
Step 8: Connect the neutral terminals as follows:
a. Connect a white wire between pin 4 (V
the ACM100. This creates a "floating neutral" signal that will enable measurements to
be made without a true neutral connection.
2.4.3 Checking Connections
Once the NMEA 2000
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
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 Maretron N2KAnalyzer
DSM150/DSM250 display. Please refer to the N2KAnalyzer User's Manual, DSM150 User's
Manual, or DSM250 User's Manual, as appropriate, for details.
2.5.1 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.
2.5.1.1 Current Transducer A
There are two configurable items for Current Transducer A: amperage and direction.
If you are using the 100A current transducer (P/N #M000630), select the 100A option. If you are
using the 400A current transducer (P/N #M000612), select the 400A option.
For the direction setting, if you notice that the current of phase A is negative when it should be
positive, or vice-versa, then the current transducer has been installed backwards. If this
happens, then instead of reconnecting the current transducer, you may change the value of this
parameter from the default value of "Normal Install" to "Inverse Install" to correct for this.
