3.6 STATIC BY-PASS SWITCH (SBS) UNIT
The static by-pass switch (SBS) unit monitors the AC bypass input and DC
input. The Inverter System operates primarily on DC and transfers to Ac
automatically upon DC failure. The maintenance bypass switch should
remain in position “0” for normal operation.
The SBS module can only be unplugged or inserted into the shelf when
the manual maintenance by-pass switch is in position 1 or 2.
