DC Wiring
CAUTION: Equipment Damage
Never reverse the polarity of the battery cables. Always ensure correct polarity.
CAUTION: Fire Hazard
Always install a circuit breaker or overcurrent device on the DC positive conductor
for each device connected to the batteries.
CAUTION: Fire Hazard
Never install extra washers or hardware between the mounting surface and the
battery cable lug or interconnect. The decreased surface area can build up heat.
Terminal Hardware
NorthStar NSB BLUE+
®
battery terminals consist of a threaded stud which receives a nut
.
Terminal hardware is assembled as shown in
below.
NOTE:
Install the cable lugs (or interconnects) and all other hardware in the order
illustrated. The lug or interconnect should be the first item installed. It should
make solid contact with the mounting surface. Do not install hardware in a
different order than shown.
To avoid corrosion, use plated lugs on cable terminations. When multiple
cables are terminated, use plated terminal bus bars.
Tighten the terminals to a torque value of 71 in-lb (8 Nm).

Cleaning Battery Terminals
To minimize contact resistance, it is important that the brass terminals of the batteries are
cleaned of any oxidation that may have occurred during transportation and storage. It is most
convenient to clean them prior to placing them on the rack.
