2.8.5 AC Output Wiring
CAUTION: The inverter’s AC output must never be con-
nected to an AC power source. This will cause severe dam-
age to the inverter and is not covered under warranty.
Info: When using the MMS-E Series inverter in a caravan
application (under certain conditions, and provided that
the wire is properly sized for the protecting breaker),
some standards permit the breaker in the main distri-
bution panel and/or the supplemental breakers on the
inverter to provide adequate protection for the AC output
wiring. Please check your local codes fi rst.
Follow the steps below to hardwire the AC output of the MMS-E Se-
ries inverter:
1. Remove the 12.7 mm knockout on the AC Output Connection (see
Figure 1-2, Item 9) – use a utility knife to cut through the round slot.
2. Discard this knockout and install a 12.7 mm (1/2”) strain relief
in the AC OUT opening. You may need to fi le the opening edge for
proper fi t.
3. Run a 2-conductor plus ground cable through the strain relief in
the AC OUT opening. Refer to Table 2-4 for the minimum wire size
and the overcurrent protection required for the AC output wiring.
