Manual Bypass Operation (for UPS maintenance or replacement)
WARNING! For qualified service personnel only. Failure to follow the bypass procedure completely will not adequately power down
the UPS power/battery module, resulting in the continued risk of death or injury from potential contact with high voltage. The UPS's
power/battery module and detachable PDU are extremely heavy. This procedure requires several people to perform.
The UPS system includes a self-contained power/battery module along with an independent, detachable PDU with a bypass switch. This switch
allows qualified service personnel to remove the detachable PDU from the power/battery module for routine maintenance without disrupting
power to connected loads. While this switch is set to "BYPASS", connected equipment will receive unfiltered AC mains power, but the
equipment will not receive battery power in the event of a blackout.
Note: An optional detachable PDU with hardwire input/output is also available separately from Tripp Lite. Contact Tripp Lite for details.
(Optional: During a hot-swap, the PDU can be housed in the back of the rack configuration using supplied PDU hanger brackets and hardware.
See STEP 1 below for mounting instructions.)
UPS Power/Battery Module Removal
STEP 1. (Optional) Attach a PDU hanger bracket to the right and left side, rear mounting rails 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 brackets in a U space close to where the UPS and PDU are mounted in. Be sure to mount both left and
right brackets in the same U space on each side.
STEP 2. Disable PowerAlert Software and disconnect communication cable(s) from the communication port(s)
battery module.
STEP 3. Press the UPS's "OFF" Button
message shown in the LCD Display
display "Bypass Out of Range, Unable to Bypass" and will cancel the request. Repeat this procedure. If the error persists, contact
Customer Support.
STEP 4. Turn the detachable PDU's Bypass Switch
STEP 5. If an external battery module is connected to the UPS
STEP 6: Remove the five screws that hold the detachable PDU to the power/battery module.
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 supported by the UPS's
rackmount rails. Remove the rackmounting hardware from the front panel of the UPS; slide the power/battery module forward,
and remove. The PDU will remain supported on the rackmount rails. Care should be taken in this process because the PDU will
not be secured to the rack with hardware of any kind.
• If it is desired to leave the detached PDU in the rack, hang the unit in back of the rack on the installed PDU hanger brackets 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.
