Installation
Operation
Turn the switch to the ON position. The neon indicator in the switch should illuminate. If the indicator fails
to illuminate, recheck the connection, AC outlet and the fuse inside the power supply.
The PWS120 is cooled by convection and has no over temperature shutdown. Ensure adequate ventilation
for cooling.
The PWS240 is cooled by convection and forced air (via a fan). The fan operates when the transformer tem-
perature exceeds 70 degrees Celsius. If for some reason the temperature should exceed 100 degrees Celsius
the unit will shut down. After the unit has cooled down it will resume normal operation.
NOTE:
Place the unit in a well ventilated, open and cool area. Do not block the openings of the fan intake at the
bottom of the unit or the exhaust openings at the side of the unit!
This unit may be converted from 110Vac input operation to 220Vac input operation. For
instructions on this conversion please call Analytic Systems at 800-668-3884.
◆
MOUNTING
Mount the unit in a DRY location. Allow at least 1 inch of clearance around the unit for adequate cooling.
Do not block the ventilation slots on the sides of the unit.
◆
POWER CONNECTION
Ensure the switch is in the OFF position. Connect the power cord to the power supply then connect the
power cord to the AC source. Connect the output of the power supply to the DC load. The RED terminal is
the positive output and the BLACK or WHITE terminal is the negative output.
