Installation
Connecting the Battery Bank to the Inverters
The following instructions are illustrated in Figure
To connect the battery (or battery bank) to the inverters:
1.Connect POSITIVE cables:
a)one cable from the battery POSITIVE terminal to a circuit breaker in the DC disconnect (torque to manufacturer’s recommendations). The DC disconnect should be located as close to the batteries as possible.
b)a second cable from the same battery POSITIVE terminal to another circuit breaker in the DC disconnect.
c)a third cable from the first circuit breaker in the DC disconnect to the L2 inverter POSITIVE (+) terminal.
d)a fourth cable from the second DC disconnect to the L1 inverter POSITIVE (+) terminal.
2.Connect NEGATIVE cables:
a)one cable from the same battery NEGATIVE terminal (torque to manufacturer’s recommendations) to the ground bond in the DC disconnect.
b)a second cable from the same battery NEGATIVE terminal (torque to manufacturer’s recommendations) to the ground bond in the DC discon- nect.
c)a third cable from the ground bond in the DC disconnect to the L2 inverter NEGATIVE
d)a fourth cable from the ground bond in the DC disconnect to the L1 inverter NEGATIVE
3.Ensure the correct polarity of the cables with a DC voltmeter (DVM).
4.Use an insulated 1/2 inch wrench or socket to tighten the 5/16 SAE nuts to
5.After tightening the connections on the batteries, apply antioxidant paste to the battery terminals, if desired. Do not apply antioxidant paste to the inverter terminals.
6.Install the battery terminal covers (if
