6 Operation

6.1 Commissioning

The PowerWave 33 is a high quality electronic machine, which must be commissioned by a fully trained
and certified field service engineer before being put into use.
The commissioning of the UPS involves the connection of the UPS and battery, the checking of the
electrical installation and operating environment of the UPS, the controlled start-up and testing of the
UPS and customer training.
OPERATIONS INSIDE THE UPS MUST BE PERFORMED BY A SERVICE
ENGINEER FROM THE MANUFACTURER OR FROM AN AGENT CERTIFIED
BY THE MANUFACTURER.
WARNING!

6.2 Parallel - multicabinet- configuration

The PowerWave 33 S3 UPS may be paralleled for power capacity or for redundancy indefinitely. The
parallel kit is optional. Every UPS unit in a parallel configuration is provided with a proper output parallel
Isolator (IA2) which, when opened isolates the corresponding unit from the parallel system. Once the
parallel isolator (IA2) of a unit is open that unit (module) is isolated from the rest of the parallel system
and therefore does not provide power to the output. For example if you perform the command "LOAD
TO BYPASS" on any unit, all the units will transfer the load simultaneously to mains and if you perform
the command "LOAD TO INVERTER" on any unit all the UPS's will simultaneously transfer the load to
the inverters.

6.2.1 Installation instructions

THE OPERATIONS DESCRIBED IN THIS CHAPTER MUST BE PERFORMED
BY A SERVICE ENGINEER FROM THE MANUFACTURER OR FROM AN
AGENT CERTIFIED BY THE MANUFACTURER.
WARNING!
IN ORDER TO ACHIEVE EQUAL LOAD SHARING BETWEEN THE UPS-
CABINETS, THE INPUT CABLE LENGTHS FROM THE INPUT DISTRIBUTION
BOARD TO THE UPS AND FROM THE OUTPUT CABLE TO THE OUTPUT
DISTRIBUTION BOARD SHOULD BE THE SAME RESPECTIVELY.
WHEN CABLING THE UPS'S BEWARE TO CONNECT INPUT AND OUTPUT
WIRES TO THE CORRESPONDING TERMINALS, RESPECTING THE SAME
PHASE SEQUENCE ON ALL UPS CABINETS.
NOTE
EXAMPLE:
PHASE1 OF UPS1 = PHASE1 OF UPS2 = ...... = PHASE1 OF UPS N.
