WARNING!
The fan supplied with the system operates on 12VDC or
24VDC. It is thermostatically controlled to turn on if temperature ex-
ceeds 45C. It cannot be connected to 48V battery voltage. It can be
connected to the Aux output of the controller set to 24VDC or it can be
connected across one of the batteries in the array.
STEP 7:
Before attaching the battery cables to the batteries, first re-
move the battery cable fuse. This will prevent accidental short circuit.
Connect the battery cables to the batteries. Con-
nect the Temperature probe from the controller to
any of the battery terminals. The temperature sens-
ing lug is just a mechanical connection so it doesn
’
t
matter which terminal it is connected to (+ or
-
). The
probe has no polarity when connecting to the con-
troller.
