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 PWS1000R.
A ground stud is provided to bond the chassis to local ground to reduce or eliminate EMI.
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.
For 12Vdc Model Only!
For 12 Vdc models only, the output terminals must be connected as shown below if the load current is
greater than 50 amps!

MOUNTING
Mount the unit in a DRY location. Allow at least 4 inches of clearance around it 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
