The WCS1-4 power supply is shipped from the factory with a 1.6-amp fuse installed for 100/120 VAC 
input power. To use input power of 240 VAC, change the 1.6-amp fuse to a 500-milliamp fuse 
(supplied).

To change the fuse remove the lid to the fuse holder (refer to Figure 4) located inside the power supply 
and then install the new fuse. Store extra fuses (supplied) in the spare fuse holders.

To install the input power wires to the WCS1-4 power supply, refer to Figure 4 and do the following:

1. Determine the size of the input wire needed.

2. Bring the wiring into the WCS1-4 through the conduit fitting.

3. Attach the neutral input power wire to the 100V, 120V, or 240V NEUTRAL connection on the 

Primary Line Input connector strip. Attach the hot wire to the LINE connection on the same 
strip.

4. Attach the input ground wire to the No. 6 ground stud, located between the conduit holes, and 

tighten the wire with the nut and washer (supplied).

WARNING: The WCS1-4 does not have an on/off switch. Turn off power at the circuit breaker 
before wiring the power supply.
