CAUTION
ELECTRIC SHOCK:
Do not touch the energized surfaces of any electrical component in
the battery system. Before servicing the battery, follow all procedures to fully de-energize
the battery system and use safe handling procedures when handling the battery.
Failure to follow these instructions may result in injury.

This task should be performed by qualified personnel:
• Use only insulated tools
• Wear personal protective equipment
• The battery system must be de-energized
• Battery cables must be disconnected
• Battery terminals must be protected from short-circuiting and touch
Refer to
Section 8.5
Terminal Connections and Hardware
,
Section 8.6
Single Battery
Installation Procedure
and
Section 8.7
Parallel Battery Installation Procedure
.
1. Ensure that the DC system is de-energized, and the battery charger and
all loads are disconnected. If the circuit of equipment that the battery is
installed in has a disconnect, open the disconnect to isolate the batteries.
2. If connected to others, remove the battery and isolate it.
3. Protect the battery terminals from short-circuiting and touch by
covering them with terminal covers or electrically rated tape.
4. Open the fuse cover and remove the nuts holding the fuse and replace
it with a new fuse paying strict attention to orientation and the fuse
ratings in
Table 11-1
DLP Fuse Specifications
.
5. Torque the nuts holding the new fuse to 13 Nm (9.6 ft-lb).
6. After removing the terminal protection, reinstall the battery into the
system and replace the fuse cover.
7. If installed, close the disconnect to complete the circuit of equipment
and energize the battery system.
NOTICE
Failure to torque up to specification may increase resistance and lower voltage,
leading to burnout of the terminals and voiding the warranty. Torquing up over the
specification may cause the battery casing to crack, voiding the warranty.
