Lock-out/Tag-out
The BPM comes with a Lock-out/Tag-out (LOTO) feature to keep the BPM bypass switch locked in SERVICE
mode while qualified service personnel works on the UPS. To use the LOTO feature:
1.
Press and hold the red bar (see Figure 19).
Figure 21. LOTO Feature
2.
Install a lock and tag in any opening at the base of the switch according to LOTO procedures.
3.
Remove the lock and tag to reset the LOTO position.
No Break Transfer from Service Bypass to UPS Mode
After the system has been placed into SERVICE mode, it must be returned to UPS state to resume normal
operation.
CAUTION
It is critical that the following steps are followed to ensure correct and safe operation.
To turn the BPM to UPS mode:
1.
Turn the switch from SERVICE to LINE (see Figure 22).
The UPS is now in LINE mode and is energized. It is often best practice to check the UPS status and
configure settings in this mode before transitioning to UPS mode. Simply check the status of the UPS
through the front LCD menu to ensure the UPS is prepared for use.
