USING FEATURES AND OPTIONS
The RMP contains a local horn and the backlit status indicators listed in Table 10‐1.
Table 10‐1. RMP Status Indicators
SYSTEM NORMAL
The UPS is energized (either with utility power or battery backup) and is
supplying conditioned power to the critical load.
NO REDUNDANCY
This indicator applies only to parallel systems when one cabinet is not
functioning.
ON GENERATOR
The UPS input and bypass are being supplied by the power from the genera­
tor instead of from the utility power.
ON BYPASS
The bypass source is supplying the critical load. Usually this means that
the UPS is not energized. The load is not protected in Bypass mode, and a
horn sounds after 30 seconds.
UPS ALARM
The UPS system is issuing an alarm. Conditions that affect the current
UPS mode are indicated by the indicators and horn on the UPS.
ON BATTERY
The UPS battery backup is supplying the critical load. The utility power is
either interrupted or out of specification. The SYSTEM NORMAL indicator
is also illuminated.
BYPASS UNAVAILABLE
The UPS system is in Normal mode, but a bypass source is not within
specification. A horn sounds after 30 seconds.
SHUTDOWN IMMINENT
The UPS is preparing to shut down because the UPS is in Battery mode
and the DC voltage is approaching its low limit. This indicator is
accompanied by a horn.
