Verify that the bypass source is available (Bypass lamp on UPS mimic display is
green).
2.
Perform a manual transfer to bypass mode on the UPS by pressing and holding the
ESC key while simultaneously pressing the UP-ARROW key.

Verify that the UPS output is ON BYPASS by observing that the lamp associated
with the bypass line at the static switch block on the mimic display is green and that
the lamp associated with the inverter is not lit.
4.
Operate the MBS to put it in bypass mode.
It is now safe to turn off the UPS and close the battery breaker(s). Restart the UPS. To
transfer back to normal mode:
1.
Verify that the UPS is still ON BYPASS by observing the mimic display. If not,
perform a manual transfer to bypass as described, above.

3.
Enable automatic transfer by pressing and holding the ESC key while
simultaneously pressing the DOWN-ARROW key. After a few seconds, the mimic
display should show that the static switch has transferred the load to inverter.

Battery life is highly dependent on the ambient temperature and the number and depth of discharge cycles.
A discharged battery should be recharged as soon as possible. If the battery is left in a discharged state,
irreversible sulfation occurs, reducing the capacity (run-time) of the battery.
2
Some model configurations will use 36 batteries per string. 36 battery models are not part of the UL listing.
