Connection
3
Power ON the primary power module, being sure that all output
breakers (SUPDMB20K, SUPDMB20KIEC & SUPDMB20K8)
are OFF.

After primary power module start-up is complete, power ON
the secondary power module. The UPS systems will self detect
the Parallel Mode and show the following screen shots for the
master and slave power modules:
When the unit is in Parallel Mode the primary power module
will display "Parallel: Master" and the secondary power module
will display "Parallel: Slave".

Once Parallel Mode is detected, turn ON all output breakers
(SUPDMB20K, SUPDMB20KIEC & SUPDMB20K8) on the PDU.

Manual Bypass Operation

WARNING! For qualified service personnel only. Failure to follow the bypass procedure completely will not
adequately power down the UPS, resulting in the continued risk of death or injury from potential contact
with high voltage. The UPS and detachable PDU are extremely heavy. This procedure requires several
people to perform. Please read the procedure completely before proceeding. Failure to follow the UPS
removal procedure correctly may result in a loss of power to the protected load.
The UPS system includes an independent, detachable PDU with a Maintenance Breaker Switch. This switch allows qualified service
personnel to remove the detachable PDU from the UPS for routine maintenance without disrupting power to connected loads. While this
switch is set to "BYPASS", connected equipment will receive unfiltered AC mains power. However, equipment will not receive battery power in
the event of a blackout.
UPS Removal
STEP 1. Disable PowerAlert and disconnect the SNMP , serial or USB communication cables from the communication ports on the UPS. Do
NOT remove the parallel cable at this point. A disconnection of the cable before the power module is properly shut down can result
in multiple error messages depending on your configuration.
STEP 2. Before proceeding, determine your maintenance status (i.e. which UPS system requires maintenance and whether you are in
Redundancy or Power Mode per the Output/Bypass Breaker Operation chart on page 9).
