Battery Replacement

Overview

1. When the Battery Replacement LED (Red) lights up, you may leave the UPS to be re-charged for at
least 8~10 hours to see whether the Red LED will be extinguished after the Self-Test function is
executed again.
2. In case the Red LED remains unchanged, you may unscrew the Hot Swappable Battery cover to
replace a new battery, then press the "On" Switch to disable the Red LED.
Once the battery is disconnected, the loads are not protected from power outages.

Assembling the Battery Pack

The UPS battery needs to be assembled before installation: the battery pack consists of four individual
batteries, a connector wiring package (one large wire harness with two black and two red wires attached
to a four-pin connector and two separate red wires), and the aluminum battery case components.
Each battery has color-coded contacts, with red for "positive" and black for "negative". Each battery will
lie on its side in the battery case, as part of a pair, with the contacts of one at the opposite end as the
contacts of the other. The completed battery case will not slide into the unit when wired if the batteries
are not in this position when the case is assembled. (See FIG. 20)
FIG. 17 Connecting the batteries to each other and to the 4-pin connector

Remove the batteries from their packing material and stand them upright on the bottom of the
battery case, making two pairs. Alternate the batteries so the contacts of one in each pair are
opposite the contacts of the other. (See FIG. 17)
With the contacts facing up, take the large wire harness (the one with the yellow 4-pin
connector at one end) and connect each pair to the assembly. Make sure that the color of each
wire, red or black, matches the color of the battery contact. Only attach one wire from the
harness to each battery.
