7 – Operating Modes
7-8 Manual Bypass Mode (Parallel UPS—MUS)
Similar to manual bypass mode for a single UPS system
(Section 7-4), except with parallel UPS systems (2 to 4).
Note: All UPS systems must be switched into manual bypass
mode.
The diagram illustrates the manual bypass mode for a
2x MUS.
7-9 External Maintenance Bypass Mode (Parallel UPS—MUS)
Utilizing the external parallel cabinet with system level
maintenance bypass panel, the parallel UPS systems can be
completely isolated for maintenance or repair procedures
while the connected equipment remains powered.
Transfer to external maintenance bypass mode should only
be accomplished once each individual UPS unit has been
placed in auto or manual bypass first.
