WARNING
If you are not knowledgeable about electrical systems, have an
electrical professional install this unit. The diagrams in these
instructions pertain to the installation of the unit and not to the overall
wiring of the vessel.
Verify that all AC sources are disconnected before connecting or
disconnecting the Current Transformer (CT). Failure to do so will
generate lethal voltages on the CT.
If an inverter is installed on the vessel, its power leads must be
disconnected at the battery before the unit is installed. Many inverters
have a "sleep mode" in which their voltage potential may not be
detectable with measuring equipment.
If an AC generator is installed on the vessel, it must be stopped and
rendered inoperable before the unit is installed.
Verify that no other DC or AC sources are connected to the vessel's
wiring before installing the unit.
If the unit must be removed, connect the CT leads together before
restoring power to the AC system.
CAUTION
The back of the unit is not waterproof. Do not install where the
back of the monitor is exposed to water.

Installation Steps

1. Choose meter mounting style and location
2. Turn of all power, both AC and DC.
3. Prepare mounting hole using cutout templates
4. Using wiring diagram:
• Install provided 500A/50mV Shunt for DC
current and SoC monitoring
• Install provided 150A/50mA Current
Transformer for AC current monitoring.
• Make all connections to the meter's connector.
Do not put fuses into fuse holders at this time.
5. Plug wired terminal block into the meter
6. Insert fuses into fuse holders, making the fuse to
Pin C2 (DC Supply/Battery 2+) Last.
7. Turn on Power.

Basic Meter Setup

1. Ensure Battery 1 (House Battery) is fully charged
2. Have Battery 1 information ready
a. Battery Bank Nominal Voltage
b. Battery Type
c. Battery Capacity
3. Navigate to DC 1 Setup by going Menu>Setup>
DC1 Setup.
4. Enter information for Battery 1 from step 2
5. Select Set SoC to Full. This reset the meter SoC
to 99%.
6. AC Monitoring requires no setup if using the
included 150A/50mA CT.
7. For instructions on setting Alarms, calibrating
tank senders, or setting up Bilge monitoring see
the full instructions found on our website.
