Manual Bypass Operation
UPS Power/Battery Module Removal
STEP 1. (Optional) Attach 2 PDU hanger brackets to the right-side, rear mounting rail
using included screws and cage nuts. Important: determining where to
attach your PDU hanger brackets will depend on your rack configuration.
Generally it is recommended to mount the top bracket in the bottom two
square holes of the U space that the UPS and PDU are mounted in. The sec-
ond bracket should be installed 3U measures down and placed in the top two
square holes of the U. (For example: If the PDU and UPS are mounted in 7U,
the first bracket will be installed in the bottom two square holes of 7U. The
second bracket would be installed in the top two square holes of 4U.
STEP 2. Disable PowerAlert Software and disconnect communication cables from the
communication ports
STEP 3. Press UPS's "OFF" Button
and see a "BYPASS MODE" message shown in the LCD Display
STEP 4. Turn the detachable PDU's Bypass Switch
STEP 5. If an external battery module is connected to the UPS
UPS.
The UPS power/battery module is now safely powered down and it can be
detached from the PDU to perform maintenance/replacement.
STEP 6: Remove the four screws that hold the detachable PDU to the power/battery
module.
WARnIng! High Voltage! Risk of electrical shock! SEE BELOW.
STEP 7: Using several assistants at each end, carefully pull the detachable PDU away
from the power/battery module. During this process, ensure that each section
is properly supported after they are separated. If the sections are detached in
a rackmount application, ensure that each section remains adequately sup-
ported by the UPS's rackmount rails. Remove the rackmounting hardware
from the front panel of the UPS; slide the power and battery modules for-
ward, and remove. If it is desired to leave the detached PDU in the rack, hang
the unit in the back of the rack on the installed PDU hangers by the screws
used to attach the PDU to the UPS system.
If the sections are detached in a tower application, ensure that the PDU is
supported by the UPS's tower feet. Adjust the tower feet so they are as close
together as possible.
