Check the individual Battery Voltages:
For each Battery Shelf:
1. Switch the Breaker on the Battery Shelf (Battery Housing Assembly) to the OFF
position
2. On each Battery (four per shelf) measure the voltage between the Positive and
Negative Terminals (there is no need to remove the linking bars). Note these
voltages on the PI sheet.
3. Switch the Breaker on the Battery Shelf back to the ON position
When all shelves are complete, please check that all of the Battery Breakers are set back
to the ON Position
13.2 Maintenance Bypass Switching
The Maintenance Bypass feature allows maintenance personnel to connect the controller
load directly to the mains supply from the site feeder pillar via the Alpha UATS bypassing
the FXM UPS unit and its connected battery packs. See section 10 for isolation switch
information.
Flip SW1 on the UATS from 'UPS' to 'BYPASS' to instantly set the UPS Solution to
Bypass mode. The controller load will not experience a break in power.
WARNING: When set to Bypass in this fashion, mains powers is still being
used by the UPS unit to charge connected battery packs and all terminals
directly connected to the UPS unit are live. To isolate and switch off the UPS
unit, see section 13.3.
NOTE: Use of the BYPASS Switch may cause the attached control equipment
to restart, it should only be used when replacement of the FXM unit is required
(Please see Section 13.4.3).
See section 4.2 for more information on the UATS.
