Introduction

The left side of MS-G Series inverters are equipped with the following features (refer to Figure 1-3):

Exhaust Air Vents – ventilation openings that allow heated air to be removed by the

internal cooling fan.

Model/Serial Number Label – includes model/serial number information, date of

manufacture, and inverter and charger specifi cations. See the MS-G Series specifi cations

in Appendix A for more information and a list of available models.

AC Access Cover – provides access to the internal AC wiring terminal block (see

Figure 2-10). This terminal block is used to hard wire all inverter AC input and output

wiring connections. Remove the two screws to access the AC wiring terminal block.

Note: The MS2000-G model does not have the AC wiring terminal block.

GFCI (Ground Fault Circuit Interrupter) – a 20-amp rated dual outlet that quickly

stops the flow of electricity in the event a ground fault occurs on the device that is plugged

into the inverter.

HOT 1 Input – this 30-amp circuit breaker protects the unit’s internal charger wiring

and pass-thru relay while in Standby mode. The circuit breaker pops out when it opens—

press in to reset. The input circuit breaker is not branch-rated, therefore branch-rated

circuit breakers must be installed in the inverter’s input wiring.

GFCI Output – this 20-amp circuit breaker is branch-rated and protects the wiring to the

GFCI outlet. This circuit breaker pops out when it opens—press in to reset. It can also be

manually pulled to disconnect the inverter’s loads.

CAUTION: The inverter’s internal AC transfer relay is rated for 30 amps per wired input

(not the GFCI circuit). The pass-thru current must be no greater than 30 amps per leg

or damage to the relays may occur.
