Introduction
The left side of the ME Series is equipped with the following features (see Figure 1-3):
13
Exhaust Air Vents
– ventilation openings that allow heated air to be removed by the
internal cooling fan.
14
Model/Serial Number Label
–
includes model/serial number information, date of
manufacture, and inverter and charger speci
fi
cations. See the ME speci
fi
cations
in
Appendix A for more information and the different models that are available.
15
AC Access Cover
– provides access to the internal AC wiring terminal block (see Figure
2-8). This terminal block is used to hardwire all inverter AC input and output wiring
connections. Remove the two screws to access the AC wiring terminal block.
16
Input Circuit Breaker (CB1)
– this circuit breaker protects the unit’s internal charger
wiring and pass-thru relay while in Standby mode. This circuit breaker will pop out when
it opens. Press in to reset. This input circuit breaker is not branch-circuit rated, therefore,
branch-circuit rated breakers must be installed in the inverter’s input wiring.
Output Circuit Breakers (CB2 & CB3)
– these circuit breakers are branch-rated, but
are only provided on the ME2012-15B/-20B models. They allow the inverter AC loads to
be connected directly to the inverter’s output without requiring an inverter sub-panel.
These circuit breakers pop out when they open. Press in to reset. They can also be
manually pulled out to disconnect the inverter’s loads.
Note:
Models without AC output
breakers (CB2 & CB3) use carriage bolts to
fi
ll the breaker openings.
CAUTION:
Inverter models without the output circuit breakers (CB2 and CB3) must
have branch-rated circuit breakers installed in the inverter’s output wiring.
CAUTION:
The inverter’s internal AC transfer relay is rated for 30 amps per leg. The
pass-thru current must be no greater than 30 amps per leg or damage to the relays
may occur.
