Now, follow these steps to connect the cables:
1.
Using the battery-wiring diagram, determine which batteries belong to each
battery string.
2.
Clean the cable connectors with the wire brush before you make the battery
connections.
NOTE As you carry out the following step, use these guidelines:
If you are using conductive grease, apply a thin coating of high-temperature
conductive grease on each post and every cable connector before you assemble
and torque the connection to slow corrosion.
If you use nonconductive grease like petroleum jelly, do not apply any grease
before you make the connections and torque them. Instead, make the connection
first; then, torque it to the value shown in Table 6.1. After you make the connection;
apply a coating of the nonconductive grease to the hardware at the battery
terminals.
3.
In each battery string, connect the battery cables between the batteries as
shown in the battery-wiring diagram (positive terminal to negative terminal).
Torque the connections to the value shown for your battery in Table 6.1.
4.
Connect the battery cables from one shelf to the next as shown on the battery-
wiring diagram.
5.
Connect the fuse block to the positive of the battery as shown on the battery-
wiring diagram.
CAUTION
Hazardous voltage is present! System batteries are high current sources. These
batteries can produce dangerous voltages, extremely high currents, and a risk of
electric shock.
6.
Install the battery cabinet(s) fuse(s). Next, use the voltmeter to check the DC
voltage between the positive (+) position on the battery block inside the
electronics cabinet and the unconnected battery negative terminal. This voltage
should be approximately the battery voltage record on the unit ID label. If it is
greater than + or – 5%, review the battery wiring diagram. Correct any wiring
errors and recheck the DC voltage; do not go on until your measurement is
or – 5%. If the measurement is too high and you cannot find the cause
of the problem, call SERVICE.
