NOTE:
A small amount of arcing may occur when connecting an ERM to the UPS. This is
normal and will not harm personnel. Insert the ERM cable into the UPS battery connector quickly
and firmly.
9.
Plug the ERM cable(s) into the battery connector(s) as shown in Figure 12 on page 13.
Connect red to red, black to black, and green to green. Press the two parts tightly
together to ensure a proper connection.
To connect a second ERM, unclip the ERM connector on the first ERM and pull gently to
extend the wiring to the ERM connector on the second ERM. Repeat for any additional
ERMs.
10.
Verify that the ERM connections are tight and that adequate bend radius and strain
relief exist for each cable.
11.
Replace the ERM front bezel.
To replace the bezel, verify that the ERM cables are routed through the ERM cable
knockouts. Slide the bezel from the left to the right until it connects with the bezel hook
near the left side of the ERM cabinet. Tighten the two captive screws on the right side
of the front bezel. For reference, see Figure 23 on page 31.
Repeat for each additional ERM.
12.
Verify that all wiring connecting the UPS and ERM(s) is installed behind the front bezels
and is inaccessible to users.
13.
Replace the UPS right front bezel.
Testing New Batteries
NOTE:
The UPS conducts the battery test on the UPS internal batteries and any connected ERMs.
To test new batteries:
1.
Plug the UPS into a power outlet for 48 hours to charge the batteries.
2.
Press the (Output On) button on the UPS front panel for at least one second.
3.
Verify that the (Power On) indicator is illuminated, indicating that the UPS is
operating normally and any loads are powered.
The UPS should be in Normal mode.
4.
Press the (Output On) button for half a second to initiate the battery test.
If the UPS is in Normal mode with no active alarms and the bypass voltage is
acceptable, the UPS starts a battery test.
During the battery test, the UPS transfers to Battery mode and discharges the batteries
for 25 seconds under the existing load. The
(On Battery) indicator illuminates.
