FUSE INSTALLATION
The WCS1-4 power supply is shipped from the factory with a 1.6 A fuse installed for 100/120 VAC input
power. To use input power of 240 VAC, change the 1.6 A fuse to a 500 mA 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.
INPUT POWER WIRING
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 100 V, 120 V, or 240 V connection on the Primary Line
Input connector strip. Attach the hot wire to the COM connection on the same strip.
4. Attach the input ground wire to the No. 6 ground stud, located between the conduit holes, and then
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.
