NOTE If you have an external DC disconnect switch between the UPS and batteries,
see the instructions that came with your disconnect switch.

8. Clean the cable and battery post (terminal) before you make

the battery connection. Apply a thin coating of
high-temperature conductive grease on the post and cable
terminals to slow corrosion. If you use a nonconductive grease
like petroleum jelly, do not apply any grease before you make
the connections. Instead, make the connection first; then,
torque it to the torque values shown below for your battery.
After you have made the connection, apply a coating of the
nonconductive grease to the hardware at the battery terminals.

When you make battery terminal connections, use the torque
wrench to tighten the battery terminal connections securely.
For most batteries, you can find out what torque value to use
by finding the battery number (BAT-XXXX) on the top of the
battery. Then, use Table 28 to find the torque value for that
battery.

Table 28. Battery Torque Value

Battery Type

Torque

BAT-0046

Torque to 65 in lb (7.3 Nm)

BAT-0048

Torque to 65 in lb (7.3 Nm)

BAT-0050

Torque to 75 in lb (8.4 Nm)

BAT-0053

Torque to 40 in lb (4.5 Nm)

BAT-0103

Torque to 40 in lb (4.5 Nm)

BAT-0122

Torque to 65 in lb (7.3 Nm)

Other batteries do not have a battery number on the top. To
find the torque value for these batteries, check the battery
terminal type; then, use Figure 23 to find the torque value for
that terminal type.
