MBP Lights
The Maintenance Bypass module (MBP) light indicators are shown in Figure xx.
The lights on the MBP represent the following:
on means Load is powered directly from Line (AC power source) - the load is not
protected by the UPS unit.
This light will be on only when the Normal/Bypass switch is in the Bypass position. It is
intended as a reminder that the load is not protected during UPS maintenance.
on means the UPS output is feeding the MBP (load supplied by UPS).
This light will be on any time the UPS is providing power and is independent of the position of
the Normal / Bypass switch. It is intended as an indicator that it is safe to move the Normal /
Bypass switch from the Bypass position to the Normal position when UPS maintenance is
complete.
MBP Installation
Electronics Module is mounted directly above the Extended Battery Module, and the MBP
should be mounted directly behind the Extended Battery Module. Follow the below rules for
installing the MBP:
Mount the MBP behind the EBM that is shipped with the UPS itself. If there are multiple
•
EBMs attached to the UPS, mount it behind the EBM closest to the UPS power module.
The minimum rack depth with UPS/MBP is 900mm (35.4in).
