Introduction
The left side of MS Series inverters are equipped with the following features (Figures 1-3 & 1-4):
Exhaust Air Vents – ventilation openings that allow heated air to be removed by the
13
internal cooling fan.
Model/Serial Number Label – includes model/serial number information, date of
14
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
15
(Figure 2-10). 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.
Note: The MS2000 models do not have the AC wiring terminal block.
AC Input Circuit Breaker (CB3) – this circuit breaker protects the unit's internal
16
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
17
and are only available on models MS2000-15B, MS2000-20B, MS2012-15B, MS2012-
20B, and MS4048-20B. 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.
