The charger can be mounted horizontally or vertically. When mounting vertically, please
ensure that the axis of the fan rotor is horizontal (to reduce stress on the bearing)
OUTPUT CONNECTORS
Connectors with tubular, screw down type of terminals are used for output connection.
The diameter of the tubular hole of the connector is 8 mm (0.31 inches).
Two positive output connectors (1, 2) are provided for connecting to the positive

negative connection
For firm connection when using stranded cable, crimp / solder "pin" style terminal on the
charger end of the DC cables used for connecting to the battery / other DC loads
CABLES
To avoid polarity errors and possible damage, never use cables of only one color. Use red
insulated cable(s) for positive connection(s) and black for negative connection(s)
Recommended DC cable sizes are given below (Based on a voltage drop of 2%). The
length in feet is the length of the pair of the positive and negative DC cables from the
charger to the battery / other DC loads
