Manual Bypass Operation
(6kVA and 10kVA models only) (for power module maintenance or replacement)
The following procedure only applies to UPS system configurations that include a 6kVA or 10kVA transformer module. The procedure
details how to service or replace the power module while supplying equipment connected to the transformer module with utility power.
NOTE: since the power module and battery module will be disconnected during the procedure, they will be unable to supply battery backup
support to equipment connected to the transformer module in the event of a blackout.
WARNING! For qualified service personnel only. Failure to follow this procedure completely will not adequately power down the
UPS power module, resulting in the continued risk of death or injury from potential contact with high voltage.
