To replace the EBM(s):
1. Unplug the EBM power cable and battery detection cable from the UPS.
If additional EBM(s) are installed, unplug the EBM power cable and battery detection cable
from each EBM.
To ease EBM replacement:
You can remove the battery pack from the EBM as explained below.
• Remove the center cover of the front panel.
• Remove the four screws to open the front panel.
• Remove the three screws to pull out the metal protection cover of the battery.
• Pull out the plastic handle of the left and right battery packs, and slide the packs out slowly on to a
flat and stable surface. Use two hands to support the battery packs.
2. Replace the EBM(s). See "Recycling the used equipment" on page 39 for proper disposal.
A small amount of arcing may occur when connecting an EBM to the UPS. This is normal and
will not harm personnel. Insert the EBM cable into the UPS battery connector quickly and firmly.
3. Plug the EBM cable(s) into the battery connector(s). Up to 4 EBMs may be connected to the UPS.
4. Verify that the EBM connections are tight and that adequate bend radius and strain relief exist for each
cable.
5. Connect the battery detection cable(s) to the connector of the UPS and of the EBM(s).
• Testing new batteries
To test new batteries:
1. Charge the batteries for 48 hours.
2. Press any button to activate the menu options.
3. Select Control then Start battery test.
The UPS starts a battery test if the batteries are fully charged, the UPS is in Normal mode with no
active alarms, and the bypass voltage is acceptable.
During the battery test, the UPS transfers to Battery mode and discharges the batteries for 25 seconds.
The front panel displays "Battery test in progress" and the percentage of the test completed.
