Maintenance Bypass Switch
rear mounted
for 8-15kVA single-phase UPS Systems


Powerware maintenance bypass switch.  Use for selected 8-15kVA single-phase UPS systems.  Mounts on rear of series 9155 uninterruptible power system.

This switch is not required if a 9155 Power Distribution Module (PDM) is used since the PDM already incorporates this switch.

NOTE:  If the UPS must ever be completely removed for maintenance or replacement it is better to have the wall mounted maintenance bypass switch BPE20MBB1A.
