Note: If the UPS system remains off for an extended period of time, it
should be turned on periodically to allow the batteries to recharge. The
UPS system should be turned on and the batteries should be recharged
at least one uninterrupted 24-hour period every 3 months. Failure
to recharge the batteries periodically may cause irreversible battery
damage.
1.6.10 Manual Bypass Procedure (Parallel UPS)
Warning: When the UPS system is in manual bypass, the inverter shuts down. Connected equipment loads are powered by the bypass
(reserve) power source and will not receive battery backup during a utility power failure.
•
For the first UPS system you wish to shut down, press the OFF
1
button
for 3 seconds (until you hear a beep), then release
A
the button. If the other UPS system can support the connected
equipment loads alone, the UPS system that was turned off will
shut down its inverter and its LCD screen will read "LOAD NOT
POWERED". The other UPS system's LCD screen will read
"ONLINE MODE". If the total connected equipment load is too
large to be handled by a single UPS system, both UPS systems
will shut down their inverters and switch to bypass mode, and their
LCD screens will read "ON AUTO BYPASS". Repeat step 1 for
the second UPS system you wish to shut down.
