Interconnect Connections between Battery Cabinets
Systems that split a battery string between 2 battery cabinets (50.0 kW system):
Find the battery cable that connects to the fuse block. At the bare end of the
cable, strip off 0.5” (1.3 cm) of insulation. Insert the cable into the fuse block.
Tighten the connection as shown on the battery-wiring diagram.
Fuse
All systems come with a fuse for each battery cabinet to protect the system. The
battery-wiring diagram shows the fuse location; a label inside the battery cabinet
shows the fuse size. The system itself has a DC fuse. At each battery cabinet,
find the cable that is connected to the other end of the fuse block. Insert the
cable. Tighten the connection as shown on the battery-wiring diagram.
Repeat this step for each cabinet.
Verify that the DC Breaker in the electronics cabinet is off and the fuse(s) in
the battery cabinet(s) are removed before connecting the batteries.
Arranging the Batteries
NOTE As you arrange the batteries, you must be wearing the required safety
equipment.
Arrange the batteries in the cabinet or the system only as shown in the battery-wiring
diagram. This arrangement is designed to maximize airflow around the batteries. The
cabinets are designed so that battery cases should never touch. Air should be free to
circulate. Clean the entire surface of all battery terminals with the wire brush before you
install the batteries to create good contact points.
Load the batteries into the system or battery cabinet(s). Starting with the bottom shelf,
load one shelf at a time.
CAUTION
Never install the batteries in an airtight enclosure.
Connecting the Cables Between Batteries
When you make battery terminal connections, use the torque wrench to tighten the
battery terminal connections securely. For most batteries, you can find out what torque
value to use by finding the battery number on the top of the battery. Then, use Table 6.1
to find the torque value for that battery.
