INSTALLATION
LOCATION, MOUNTING AND SAFETY
The charger is required to be installed in a safe, well ventilated and dry location. Please see
the details given under “Important Safety Precautions”.
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 terminals
of the 2 banks of batteries. One common connector (3) is provided for the negative connec-
tion.
TERMINAL LUGS FOR CONNECTION TO THE CHARGER
For firm connection when using stranded cable, crimp / solder “pin” style terminal lugs on
the charger end of the DC cables used for connecting to the battery / other DC loads.
3 pieces of “pin” style terminal lugs have been provided as follows:
• For SEC-1245A Will accomodate up to AWG # 4 cable
• For SEC-2425A Will accomodate up to AWG # 8 cable
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.
Distance from battery SEC-1245A SEC-2425A
Up to 6 ft. AWG # 6 AWG # 10
6 to 10 ft AWG # 4 AWG # 8
10 to 20 ft. AWG # 1/0 AWG # 6
