3-8 Eaton BladeUPS 12 kVA Maintenance Bypass Cabinet Installation and Operation Manual P-164000130—Rev 1 www.eaton.com/powerquality
The firmware on the UPS also provides a user setting for the Force Bypass mode feature.This setting is enabled
using the LCD menu display on the front panel of the BladeUPS. With this setup, if the UPS is accidently left
in service before closing the MBB, the signal wiring between the UPS and the MBC senses this error and
immediately forces the UPS to maintenance bypass mode.
If the IRC is removed from the UPS during operation, there is the possibly that a lethal voltage will
be on the exposed connectors on the IRC card. Only properly trained and authorized personnel
should perform service on energized IRC card.
3.3.1 Preliminary Communication Wiring Information
All wiring should be performed by a licensed electrician. Installation should be performed only by
qualified personnel.
In a parallel BladeUPS system that uses the pull chain and Powerware Hot Sync CAN Bridge Card
communication, the signal wiring from the MBC is connected to only one UPS. This UPS will
transmit bypass instructions to the other UPSs using the pull chain and Powerware Hot Sync CAN
Bridge Card communication interface.
In a UPS connected to utility power, X-Slot cards remain powered on even if the input breaker is
off.
NOTE Remove the MBC top or bottom conduit landing plate, remove knockouts, or
identify the control wiring terminations, see Appendix A.2 “Installation and Wiring
Diagram” in this manual.
