Fuse Terminal Torque

13 Nm (9.6 ft-lb)

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 6.5 

Terminal Connections and Hardware

,

 Section 6.6 

Single Battery 

Installation Procedure

 

and 

Section 6.7 

Parallel Battery Installation Procedure

.

1.  Ensure that the DC system is de-energized and, the battery charger and 

all loads are disconnected. If the battery is in a DC circuit of equipment 

has a disconnect, open the disconnect to isolate the battery.

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.  Install the fuse on the battery fuse post. The battery will not operate if 

the battery fuse is installed on the battery terminal post.

5.  Remove the nut holding the fuse and replace it with a new fuse paying 

strict attention to orientation and the fuse ratings in 

Table 10-1

 

DLB Fuse 

Specifications

.

6.  Torque the nut holding the new fuse to 13 Nm (9.6 ft-lb).

7.  After removing the terminal protection, reinstall the battery into the 

system.

8.  If installed, close the disconnect to complete the circuit of equipment 

and energize the battery system.

NOTICE

Failure to properly torque battery terminal nuts may increase resistance and lower voltage 

which may lead to burnout of the terminals and void the warranty.

11. STORAGE

Leaving the battery connected to a trickle load, or to power electronics will 

cause the battery to be discharged during storage. Without any load, the 

battery will self-discharge by approximately 3% per month while in storage. 

After storage, charge the battery to 100% SOC and then perform at least 1 full 

discharge and charge cycle before returning the battery to service.
