• Connect pin 6 of the J6: Contactors / -V Power
connector through a fuse to the negative end of
the stack
• Connect pin 1 of the J7: Current Shunt / +V Power connector directly to the load side of the current
shunt, or to ground
If the most negative end of the stack is grounded:
• A fuse is required at the positive power connection point only, in line with the connection to pin
1 of the J7: Current Shunt / +V Power connector
• Connect pin 1 of the J7: Current Shunt / +V Power connector through a fuse to the load side of the
current shunt
• Connect pin 6 of the J6: Contactors / -V Power connector directly to the negative end of the stack,
or to ground
If no ground connection exists within the stack or if a ground connection is made somewhere
other than at an end:
• Fuses are required at both the positive and negative power connection points to the Battery
Controller, in line with each of pin 1 of the
J7: Current Shunt / +V Power
connector and pin 6 of the
J6: Contactors / -V Power connector
• Connect pin 1 of the J7: Current Shunt / +V Power connector through a fuse to the load side of the
current shunt
• Connect pin 6 of the J6: Contactors / -V Power connector through a fuse to the negative end of
the stack
Fuse(s) are not supplied and must be selected based on the operating voltage range of the
connected battery stack. Use the following table as a guide to select either one or two fuses of the
same capacity.
Fuse current ratings
12V Battery (9-16V) 8A
24V Battery (18-32V) 4A
36V Battery (27-48V) 2.5A
48V Battery (36-60V) 2A

3AB/3AG fast-response cartridge fuses and in-line fuse holders are commonly
used for this application
An external 9-60V DC power source may be used (instead of the connected battery stack) to
power the Battery Controller and power the contactor coils. The positive of this source must
connect through a fuse to pin 1 of the
J7: Current Shunt / +V Power connector and the negative of this
source must connect through a fuse to pin 6 of the J6: Contactors / -V Power connector. In this
situation, pin 5 of the J6: Contactors / -V Power connector must be connected directly to the most
negative end of the stack. This will connect the negative of the external power source to the most
negative end of the attached stack, so caution must be exercised when choosing the power source
to ensure that this is acceptable and safe.
