PowerWAVE 9000 DPA UPS - Multi-Cabinet Configuration
(Issue 2.1 Oct. 2009)
IMPORTANT:
The PowerWAVE 9000 DPA BYPASS MODE (ECO-MODE) function of
a parallel system is the same as that for a single unit. If the UPS is
operating as a parallel system with the load transferred to the
BYPASS (load on mains), failure of the mains supply will initiate the
UPS system to automatically (within 5msec), transfer to each module
inverter.
IN ORDER TO PROVIDE THE LOAD WITH MAXIMUM PROTECTION
UNINTERRUPTIBLE POWER SUPPLIES LTD. ALWAYS RECOMMEND
THAT THE CRITICAL LOAD IS SUPPLIED BY THE INVERTER (ON-
LINE-MODE).
