8 – Start-Up, Shutdown and Bypass
(continued)
8-5 Manual Bypass Procedure (Single UPS)
Warning: Placing the UPS system in manual bypass will disable the inverter and power all loads from the manual bypass source, but
the UPS system will still be energized. Before performing maintenance or repair on the UPS system, shut down and de-energize the UPS
system completely by following the steps in
Section 8-6 . Although connected equipment loads will be powered by the bypass power source,
they will not receive battery backup in the event of a utility power failure.
If the UPS is in NORMAL mode (green LED ON, LCD displays •
“Load Protected – On Line Mode”), then you must stop the
inverter by pressing and holding the red OFF (“O”) button
A
until
the UPS beeps, then release the button and answer “YES” to the
question “Transfer to Bypass Mode?”. The UPS should transfer to
Bypass.
Confirm the UPS is in BYPASS • mode (amber Bypass LED is ON;
LCD displays “Load Unprotected – On Auto Bypass”). Do not
proceed if it is not in BYPASS mode.
Turn OFF the MAIN INPUT circuit breaker • Q1 .
Wait until the Power Module fans turn OFF (this may take a •
minute or two), then turn OFF the BATTERY BREAKER. On 80K
units, the BATTERY BREAKER is on the back of the matching
battery cabinet.
Note: Some external battery cabinets may have the
BATTERY BREAKER behind the front door or elsewhere.
Turn ON the MANUAL BYPASS circuit breaker • Q3 . The LCD
will display “Load Unprotected – On Manual Bypass” and you will
hear an audible alarm.
Turn OFF the OUTPUT circuit breaker • Q4 .
Turn OFF the BYPASS INPUT circuit breaker • Q2 . The unit’s LCD
will go blank after a few seconds.
The critical load is now supported by unconditioned utility power. •
8-6 Shutdown Procedure (Single UPS)
Warning: The UPS system shutdown procedure will eliminate the AC power output for all loads. Before shutdown, confirm that all loads
are turned off or place the UPS system in manual bypass mode to keep loads powered by the bypass power source.
If the UPS is in NORMAL mode (green LED ON, LCD displays •
"Load Protected-On Line Mode"), then you must stop the inverter
by pressing and holding the red OFF ("O")
A
button until the UPS
beeps, then release the button. The UPS should transfer to Bypass.
Confirm the UPS is in Bypass (amber Bypass LED is ON; LCD •
displays "Load Unprotected-On Auto Bypass"). Do not proceed if
it is not on Bypass.
Turn OFF the OUTPUT circuit breaker • Q4 .
Turn OFF the MAIN INPUT circuit breaker • Q1 .
Turn OFF the BYPASS INPUT circuit breaker • Q2 .
Wait until the Power Module fans power OFF and the LCD •
goes blank (this may take a minute or two), then turn OFF the
BATTERY BREAKER on the back of the battery cabinet.
