2. Thread the battery connector through the battery cover. Position the battery cover in place and slide it
to the left to secure it.
3. Connect the internal battery connector, as shown in Figure 325 on page 288. Each end of the keyed
connector has two wires: one red (+) and one black (−). Join the black wires and the red wires
together.
Note: A small amount of arcing might occur when connecting the batteries. This is normal and does
not damage the unit or present any safety concerns.
4. Push the front panel to the right to catch on the left end of the panel. Push the front panel forward
until the panel snaps into the right and middle sections of the 2145 UPS-1U, as shown in Figure 325
on page 288.
