8-6 Shutdown Procedure (Single UPS)
(continued)
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.
Transfer critical load to NORMAL from MANUAL BYPASS
Confirm the UPS is on MANUAL BYPASS (the MANUAL
BYPASS circuit breaker
Q3
is ON; the OUTPUT
Q4
, BYPASS
INPUT
Q2
and MAIN INPUT
Q1
circuit breakers are OFF).
Turn ON the BATTERY BREAKER on the back of the battery
cabinet.
Turn ON the BYPASS UNIT circuit breaker
Q2
. The amber
Bypass LED should come ON and the LCD will display "Load
Unprotected-On Manual Bypass".
Confirm the amber BYPASS LED is ON. Do not proceed if it is
not ON.
Turn ON the OUTPUT circuit breaker
Q4
.
Turn OFF the MANUAL BYPASS circuit breaker
Q3
. The LCD
will display "Load Unprotected-On Auto Bypass".
Turn ON the MAIN INPUT circuit breaker
Q1
. The Power
Module fans will turn ON.
Press and hold the green ON ("1") button until the UPS beeps, then
release the button. The UPS will perform its self-test diagnostics
and the LCD will display "Self Diagnosis". After the UPS self-test
is completed, the UPS will transfer to NORMAL mode (green
LED ON, LCD displays "Load Protected-On Line Mode").
Confirm there are no active alarms present ("!" on the display and
audible beeping). If an alarm is present, press the UP or DOWN
arrows to display the active alarm. Correct the action as required.
Scroll through the Measure Menu and confirm all input and output
power readings are within the recommended specifications.
If any problems are noted, contact your technical support personnel
for further assistance.
The critical load is now supported by conditioned battery back-up
power.

8-7 Preliminary Checklist (Parallel UPS)
Warning: Parallel configuration
requires exactly two UPS systems (1+1 configuration). Do not attempt to link more than two UPS systems
via parallel configuration. The UPS systems must have the same rating, capacity and system/power module firmware version for parallel
configuration installation. Attempting to link dissimilar UPS systems will damage the UPS systems and create a serious risk of personal
injury and property damage.
All circuit breaker switches should be off, including the breakers of the external battery cabinets.
•
Confirm that no voltage potential exists between Neutral and Ground.
•
Confirm that the input power source matches the rating (voltage, frequency and phase) of the UPS systems.
•
Each UPS must have its parallel group set to 2 and a different "Parallel ID" that indicates the UPS systems are running in
•
parallel. (See
Section 9-5-5
for more details.)
Note: After start-up, the UPS systems will perform a brief self-test and display the results on the LCD screen. After a successful self-test, the UPS
systems will provide AC power to the connected equipment load.
