CO Ground Connection
Two 10-32 studs on 5/8” centers with hardware are provided on the Return Bus for CO Ground wiring.
A CO ground lead terminated in a two-hole lug can be connected as shown in
Figure 20
.
NOTE!
10-32 studs (w/hardware) on 5/8" centers are provided for this connection. Note that one stud is
used to secure lug, the other is used for anti-rotation. Recommended torque is 20 in-lbs when using the
supplied hardware.
Battery Connections
DANGER! Although battery voltage is not hazardously high, the battery can deliver large amounts of
current. Exercise extreme caution not to inadvertently contact or have any tool inadvertently contact a
battery terminal or exposed wire connected to a battery terminal. NEVER allow a metal object, such as a
tool, to contact more than one termination at a time, or to simultaneously contact a termination and a
grounded object. Even a momentary short circuit can cause explosion and injury. Remove watches,
rings, or other jewelry before connecting battery leads. Make the DC (battery) connections last. Make
all other electrical connections without DC input power applied to the system.
DANGER! Ensure correct polarity when connecting battery leads.
To Battery Busbars
Battery and battery return leads terminated in two-hole lugs are connected to threaded studs located inside

are accessible from the front of the shelf. Refer to
Figure 20 . Observe proper polarity when connecting leads.
NOTE!
1/4-20 studs (w/hardware) on 5/8" centers are provided for these connections. Both studs are
used on Lists 2 and 6. Recommended torque is 84 in lbs when using the supplied hardware.
To Bullet Nose-Type Circuit Breaker Positions (Lists BA and NA)
Battery and battery return leads terminated in two-hole lugs are connected as shown in Figure 18 . Observe
proper polarity when connecting leads.
NOTE!
10-32 studs (w/hardware) on 5/8" centers are provided for these connections. Recommended
torque is 20 in-lbs when using the supplied hardware.
