Maintenance Bypass Switch (MBS) and Power Distribution Unit (PDU) (optional)
The 50A and 100A maintenance bypass switches allow for the safe removal of inverters or the
static transfer switch without load power interruptions.
For more information refer to STS/MBS Operation on page
.
The power distribution unit includes input circuit breakers, output circuit breakers (with 50A
MBS only) and terminals. The ac output can be connected to the rear screw terminals or to the
eight rear-mounted IEC connectors (with 50A MBS only).
