Setting The Force Bypass Firmware Option; Appendix - Eaton BladeUPS Installation And Operation Manual

Installation
Two separate contacts are required for the shunt trip REPO switch. One contact should be
normally open (NO) and rated up to 120 Vac (120 Vac is supplied by the MBC). This contact
connects to the MBC. The other contact can be either NO or normally closed (NC). This contact
connects directly to the REPO connections on the BladeUPS.
1. Verify that the UPS system is turned off and all power sources are removed. Refer to the Eaton
BladeUPS
60 kVA (N+1) systems for shutdown instructions.
2. If not already open, unfasten the front door latch and swing the doors open.
3. If not already removed, remove the front door panels. Remove the retaining screws located inside each
door at the top and bottom hinge pivot points, then lift the door off. Save the retaining screws for
reinstallation of the doors.
4. If not already removed, remove the screws securing the top internal safety shield, and remove the shield
to gain access to the terminals.
5. To install the shunt trip, remove the MBC top or bottom conduit landing plate to drill or punch conduit
holes, remove knockouts (see Appendix A.2 "Installation and Wiring Diagram" in this manual).
6. Reinstall the conduit landing plate and install the conduit.
7 . To locate appropriate terminals, and for wiring and termination requirements, see Appendix A.2
"Installation and Wiring Diagram" in this manual, and refer to the Eaton
(Preassembled and Standard Systems) For use with Eaton BladeUPS 5.1 kVA to 60 kVA (N+1) systems for
UPS cabinet terminal locations.
8. Route and connect the wiring.
9. When all wiring is complete, reinstall the safety shields.
10. Close the inside distribution panel doors and secure with the retained screws.
11. Reinstall the front door panels and secure with the retained screws.

Setting the Force Bypass Firmware Option

When the signal input wiring between the UPS and MBC is connected, the UPS firmware must be set to allow
Force Bypass mode. If the MBB is closed without first manually placing the UPS in bypass mode, this setting
causes the signal input to sense this action and immediately force the UPS to maintenance bypass mode.
This is intended as a precautionary setting and should not be used instead of the instructions to
transfer the UPS into maintenance bypass mode.

For parallel BladeUPS configurations, this setup is only required on the BladeUPS
that is connected to the MBC with the signal input wiring. If a single BladeUPS is
connected to the MBC, only set up the UPS that connected to the MBC main power
inputs and outputs.
