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 connections. 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 in
Table 28 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.
