Preliminary Checks and Startup for UPS Equipped with
Maintenance Bypass Module (MBM)
Installation inspection and startup procedures must be performed only by a
Powerware Corporation authorized service person. The procedure is normally part
of the sales contract for the UPS system.
WARNING:
Attempts to startup the UPS system yourself may damage equipment and/or
your critical load. Such attempts may also invalidate your system warranty.
Maintenance Bypass Module Operation
The MBM is provided for use with the Powerware 9315 (30---160kVA) UPS module.
WARNING:
Only persons familiar with the operation of this equipment should transfer loads.
Failure to follow the transfer sequence exactly may cause loss of power to the
critical load or may cause overload protection devices to function.
Operator Note:
MIS is to be OPENED only after MBP is CLOSED
