Installing the HI400
20
Follow the procedures given below to connect the battery to
the DC input terminals. The cables should be as short as
possible and large enough to handle the required current, in
accordance with the electrical codes or regulations applicable
to your installation. As noted above, the recommended cable
size is No. 8 AWG for compliance with NEC, CEC, and RV
codes (assuming a 40 amp DC fuse).
To ensure maximum performance from the inverter, do not
route your DC cables through a DC distribution panel, battery
isolator, or other device that will cause additional voltage
drops.
Connecting the battery to the DC input
To make the DC connections:
1. Cut the DC cables to the correct length with enough
insulation stripped off so you can properly install the type
of terminals you will be using at the battery end. At the
HI400 end, strip the wire 3/8 inch.
2. Assign one cable to be positive (+) and one cable to be
negative (–). Mark both ends of each cable to avoid
confusion during installation.
3. Switch the On/Off switch into the off position (if you
have not already done so).
4. Route the DC cables from the battery bank to the inverter.
5. Install a DC breaker or a fuse and disconnect in the
positive side of the circuit, as close as possible to the
battery. Turn off the breaker or open the disconnect
switch.
6. Attach the negative (–) cable to the negative (–) battery
terminal (or to the current shunt if a shunt is used) using
whatever connector you have selected. Tighten the
connection according to the manufacturer’s
recommendation.
