DESCRIPTION  
The WCS1-4 is a mutliple power supply designed for indoor or outdoor applications and is ideal for  
use with cameras, domes, and integrated positioning systems such as Spectra® and Esprit®. The  
WCS1-4 is capable of powering up to four units and can handle pan/tilt, heater, blower, and camera  
operation.  
The WCS1-4 power supply has one fused output and is capable of handling up to 4 amps (100 VA)  
of total load. The unit features selectable 100/120/230 VAC input power, selectable 24/26/28 VAC  
output power, and a stainless steel link-lock latch that can be secured with padlock (padlock not  
provided).

INSTALLATION  
MOUNTING INSTRUCTIONS  
To mount the power supply directly to a wallboard, wall, or concrete refer to Figures 1 through 3  
and do the following:  
1. Remove the retaining screw from the door latch of the WCS1-4 power supply.  
2. Open the door of the WCS1-4 power supply, and then remove the plug(s) from the required  
conduit hole(s) located on the bottom of the unit. Install 3/4-inch (1.91 cm) conduit fitting(s) (not  
supplied). Close the lid to the power supply.  
3. Determine the mounting location for the WCS1-4.  
4. Use the WCS1-4 power supply as a template and mark the four fastener positions on the  
mounting surface.  
5. Prepare the holes for installation.  
6. Attach the WCS1-4 power supply securely to the mounting surface with four fasteners of  
appropriate length. Fasteners between 1/4-inch and 5/16-inch diameter (not supplied) can be  
used.

WARNING: Under light load conditions and high input power voltage, output voltage  
from the WCS1-4 power supply may reach 32 VAC. Pelco recommends that all  
equipment connected to the WCS1-4 power supply be rated to handle 32 VAC.  
Pelcos Spectra® domes and Esprit® integrated positioning systems meet this require-  
ment.  
Pelco cannot be liable for any damages resulting from incorrect wiring of the WCS1-4  
power supply.

FUSE INSTALLATION  
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 230 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.  
INPUT POWER WIRING  
WARNING: The WCS1-4 does not have an on/off switch. Turn off power at the circuit  
breaker before wiring the power supply.  
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 230V 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).  
C561M-D (11/03)

OUTPUT WIRING  
To install the output wiring to the camera, dome, or positioning system, refer to Figure 4 and do the  
following:  
1. Refer to Table A and determine the output connection needed for your camera, dome, or  
positioning system. Refer to Figure 4, for the proper connector strip connections.  
2. Attach one output wire to either the Tap A (24 VAC), Tap B (26 VAC), or Tap C (28 VAC)  
connections on the Secondary Output Tap’s connector strip and attach the second wire to the  
COM connection on the same strip. Be sure that you have the proper wiring size and distances  
installed if you plan to change connections later.  
3. Close the lid to the WCS1-4 power supply, replace the retaining screw to the door latch, and  
then turn power on.

CABLE CONNECTIONS AND REQUIREMENTS  
Table A. Wiring Distances  
The following are the recommended maximum distances to wire the WCS1-4 to a Spectra III or  
Esprit positioning system.  
To determine the correct voltage tap:  
1. Pick the unit type.  
2. Find the wire gauge used (22 gauge is not recommended).  
3. Determine which secondary output tap (A, B, or C) is appropriate for the distance between the  
dome or positioning system and the WCS1-4. Distance is in feet (meters).

MAINTENANCE  
There are no user-serviceable parts except for the fuse. If the transformer in the WCS1-4 does not  
work properly, the entire environmental power supply needs to be returned to the factory for repair.  
Refer to the Warranty and Return Information for instructions on returning the WCS1-4.  
Clean the outer surface of the WCS1-4 box with a nonabrasive cleaning cloth and antistatic  
cleaner. Do not use kerosene or similar substances that may damage the surface.
