2. Keep these instructions.

3. Heed all warnings.

4. Follow all instructions.

5. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.

6. Do not install near any heat sources, such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.

7. Only use attachments/accessories specified by the manufacturer.

8. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer or sold with the apparatus. When a cart is used, use
caution when moving the cart/apparatus combination to avoid injury from tip-over.

9. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power
supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or
moisture, the apparatus does not operate normally, or the apparatus has been dropped.

10. To reduce the risk of shock, do not perform any servicing other than that contained in the operating instructions unless you are qualified to
do so.

11. An ALL-POLE MAINS SWITCH with a contact separation of at least 3 mm in each pole shall be incorporated in the electrical installation of
the building.

12. The installation method and materials should be capable of supporting four times the weight of the unit.

13. Only use replacement parts recommended by Pelco.

14. After replacement/repair of this unit’s electrical components, conduct a resistance measurement between line and exposed parts to verify
the exposed parts have not been connected to line circuitry.

The product and/or manual may bear the following marks:

This symbol indicates that dangerous voltage constituting a risk of electric shock is

Description

The WCS Series consists of multi-output 24 VAC outdoor power supplies. These power supplies provide output for one to four cameras
(depending on the dome or pan and tilt) from a single source and come in 20-A capacities. To compensate for voltage losses over long wire runs,
28 VAC outputs are also available. The power supplies allow for 120 or 240 VAC line input. These high-capacity models can handle pan and tilt
and receiver operation in addition to the camera, for integrated systems such as Spectra® and Esprit®.

WCS Series models are available with either glass fuses or self-resetting circuit breakers (poly switches). The following bullets explain the
advantages and disadvantages of each type:

• Glass fuses provide more protection than circuit breakers because they act faster and are more precise. However, they are designed for
one-time use and must be replaced when they blow.

• Circuit breakers reset themselves when the fault is corrected, which eliminates the need to replace fuses. However, they react more slowly,
are affected by temperature, and are not as accurate. The amount of current required to trip one can vary as much as 100 percent.

Since circuit breaker models do not require fuses and automatically reset themselves after the fault is corrected, the breakers are not accessible.
