2.6 CONNECTING BATTERY CABLES
Routing the stiff, heavy gauge battery cables is difficult. Two people may be needed. Exercise
extreme caution
to avoid a short
circuit across the battery terminals.
WARNING
Arcing hazard
Arcing can cause equipment damage, load interruptions, and personal injury.
Remove watch and jewelry. Use insulated tools and extreme caution when
working with a battery string.
Carefully insulate unterminated battery cable ends.
At the Power system, battery cables connect to the battery charge bus and return bus. Three battery charge and battery return bus
options are available to facilitate 2-hole lug wiring: 3/8 inch diameter studs on 1 inch centers for a single tier, 3/8 inch diameter studs
on 1.75 inch centers for a single tier and 3/8 inch diameter studs on 1.75 inch centers for three tiers.
Installing the Battery Cables:
This procedure includes the installation of up to four optional battery current transducers. Transducer mounting and wiring
information is found in Section 2.10. Ignore references to transducers in the following procedure if not part of your installation.
If the installation includes a battery disconnect switch, modify the procedure accordingly.
1.
Determine the correct battery cable size and shortest cable run. See Section 2.2.2 Selecting and Sizing DC Power Cables. The top
of the distribution section is open for easy access when routing battery cables between the battery string and the Power system
battery charge bus and return bus. See Figure 2-5 for the location of the battery charge bus and battery return bus within the plant.
2.
Mount the optional battery current transducer(s) and connect the transducer cable(s) between the transducer and the Power system
as indicated in Section 2.10. Be sure that a transducer’s battery cable opening is large enough for the selected cable diameter and
the number of cables.
3.
Run cables between the plant and battery string 1. Route either battery cable (+ or -) through the optional battery current
transducer; all battery cables routed through a transducer must be the same polarity. Transducers are marked, typically with an
arrow, to indicate current direction. (See section 2.10)
