Introduction

Figure 1-3, Left Side Features (MS2012, MS2812, MS2024, MS4024)

The left side of the MS Series inverter is equipped with the following features (see Figures 1-3 & 1-4):

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 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

2-8). 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. The MS2000

models do not have the AC wiring terminal block.

AC Input Circuit Breaker (CB3) – this 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.

AC Output Circuit Breakers (CB1 & CB2) – these circuit breakers are branch-rated

and are only available on models MS2000-15B, MS2000-20B, MS2012-15B, and MS2012-

20B. 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 to disconnect the inverter’s loads.

CAUTION: Inverter models without the output circuit breakers (CB1 and CB2) 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.
