IMPORTANT
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.

3.3.4
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.
!
IMPORTANT
This is intended as a precautionary setting and should not be used instead of the instructions to
transfer the UPS into maintenance bypass mode.
NOTE
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.
