CCTV Matrix Switch Power Supply

The Power Supply has only fuses that can be serviced. The integrity of these fuses can be visually

verified by observing the LEDs located next to each fuse holder on the front of the Power Supply. If the

LED associated with a fuse is not illuminated then the fuse needs replacing or the power supply is

defective. If replacing the fuse does not correct the problem or the fuse continually blows then the power

supply should be replaced. The Power Supply is of single piece construction and slides in to the Chassis

(to the far right) like a circuit card, however it is secured from the back of the chassis by four (4) screws

located around the AC Input receptacle.
