WARNING!
To reduce the risk of fire, connect only to a circuit provided with the required
branch circuit over-current device sized in accordance with the National
Electric Code, ANSI/NFPA 70.
The maximum size over-current device shall
not be more than 50 amperes.
WARNING!
You must connect the wires that carry the AC voltage from the Digiwatts unit
to the utility grid in the order described in this procedure.
Deviating from this
procedure could expose you to lethal voltages that can cause serious injury
and/or death.
5.3.2 Connecting the AC Wires
1) Turn OFF the main breaker in the main utility breaker box.
2) Remove the cover and disconnect LCD board connections on Digiwatts unit.
3) If you are replacing an existing inverter, disconnect the wires for the AC line you
are working within the breaker box.
4) Pull the AC wires through the conduit from the interior AC terminal of the
Digiwatts unit.
5) Connect the AC equipment-ground wire to the PE terminal labeled in within
the Digiwatts unit.
6) Connect the L and N wires to the terminals labeled L and N.
7) Connect the wires to the terminal blocks in the Digiwatts unit and tighten them.
8) Verify that all connections are correctly wired and properly torqued (2.5Nm).
Pull on the individual cables in order to make sure that they are sufficiently
secured within the terminals.
