CONNECTION AND OPERATION
NOTE!
The DC output connector has a tubular hole of diameter 0.2” (5mm)
with a set screw. For a firm connection, crimp/solder a pin type copper termi-
nal on the cable ends of your 12V DC device.
Ensure that the power supply’s ON/OFF switch is off and it is unplugged
from the AC outlet.. Switch off your 12 V DC device and connect it’s positive
and negative to the RED ( Positive ) and WHITE ( Negative ) terminals re-
spectively. Ensure that the connections are secure and tight. Plug the power
supply into the AC outlet. Press the ON/Off switch of the power supply to ON
and observe that the neon indicator in the switch illuminates. If the indicator
fails to light , recheck the connection, AC outlet and the fuse inside the
power supply.
Your 12 V DC device may now be switched on.
