INSTALLATION

MOUNTING

Mount the unit in a DRY location. Allow at least 4 inches of clearance around the heat sink fins for

adequate cooling.

POWER CONNECTION

The unit is supplied with a 5 foot power cable. This should normally be adequate to connect to a

source of power. If you must extend the power cable be sure to use a 3 conductor grounded type

extension cable. For hard wiring to a source of power, cut off the plug, and strip the wires as

necessary. The wire colours are

110 VAC 220 VAC

Black - AC Hot Brown - AC Hot

White - AC Neutral Light Blue - AC Neutral

Green – Ground Green – Ground

All connections should be made inside an appropriate junction box. The maximum current draw from

the 110 VAC supply is 14.6 amps, so a 20 amp circuit breaker should be used in the circuit panel and

for a 220 VAC supply, 7.3 amps is the maximum current draw, so a 10 amp circuit breaker should be

used in the circuit panel to feed power to the PWS1000.

OUTPUT CONNECTIONS

Two Positive output terminals and two Negative output terminals are provided. Connect only one wire

to each terminal. Ensure that the total average load connected does not exceed the continuous

current rating of the unit.

OPERATION

Turn the switch on the top of the unit on to energize the outputs. The green indicator light will glow to

indicate the proper operation of the unit.

OUTPUT ADJUSTMENT

As shipped from the factory, the unit is preset to 13.6, 27.2 or 54.4VDC. You may check this voltage

at the output terminals of the unit with a good digital voltmeter. If you wish to adjust the output

voltage, remove the cover plate (secured by 2 screws) to expose the output adjust potentiometer.

Reach in with a very small flat blade screwdriver to rotate the potentiometer. Clockwise increases the

output voltage, and counter clockwise decreases it. When you are done, replace the cover plate and

securely tighten the screws.

METERS

1 or 2 high quality 2 ½ inch analog meters can be added to the charger (factory installed only). 1

ammeter allows monitoring of total output current. 2 ammeters allow independant monitoring of the

current into each of the output terminals. 1 ammeter and 1 voltmeter allow monitoring of total output

current and output voltage.
