Wiring Vehicle Power To The 8525/8530
You may have the option of connecting power before or after the ‘key’ switch. It is
preferable to wire the 8525/8530 after the key switch – that is, the 8525/8530 cannot
be switched on without turning the vehicle key on. However, if the operator
switches the key off repeatedly for long periods during a shift, it may make more
sense to wire the 8525/8530 before the switch.
Keep in mind that the 8525/8530 will continue to operate with or without vehicle
power as long as its back up battery has sufficient charge.
If an unfused power source must be used, a fuse assembly (PN 19440) must be
added to the extension power cable (the fuse and instructions are supplied with the
cable). Use only a 10A slow blow UL approved fuse in the fuse assembly. The fuse
assembly must be located as close as practical to the DC supply, and shall connect to
the positive side of the DC supply.
