[ 8 ] Pelco Manual C2913M-F (08/05)
Power Connections
MC3610 and MC3710 Series cameras are available in AC high voltage and AC/DC low voltage types. The
voltage required to operate the camera is clearly marked on the rear panel of the camera. The green POWER
LED on the rear panel indicates that power is connected. Power low voltage cameras only from a UL Listed
Class 2 isolated power supply. Power consumption is 4 watts.
Mains Power Supply
Cameras that are intended to operate directly from the mains supply are fitted with a nondetachable power
supply cord. The voltage of operation is 110 to 240 VAC at 50/60Hz.
WARNING: When powering the camera via the screw terminals, ensure that the power
connections to the RJ45-10 connector are not used, and that any connections to the RJ45-10 are
not shorted together. The power supply must be a UL Listed Class 2 isolated type.
CAUTION: AC Operation Only - When wiring more than one camera to the same transformer,
connect the same side of the transformer to the same terminal on all cameras. Failure to connect
all of the cameras the same way will cause the cameras to be out of phase with each other and
may produce a vertical roll when switching between cameras.
Low Voltage Power Supply
Cameras fitted with an automatic-switching low voltage power supply operate at 10.8 to 13.8 VDC (12 VDC
-10% +15%) or 20.4 to 27.6 VAC (24 VAC ±15%) at 50/60Hz. Connections and polarity are indicated adjacent
to the screw terminals on the rear panel.
Refer to Table B for the recommended wire gauge and wiring distances.
WARNING: Refer to the wiring instruction label attached to the supply cord. For instances
where the camera will be connected to a socket outlet, the camera should be connected to an
easily accessible socket outlet near to the camera. For instances where the camera will be
connected to the building installation, the building wiring should incorporate a readily accessible
disconnect device, with a contact separation greater than three millimeters. This device should be
fitted into the live conductor, if that is readily identifiable, or should be 2-pole. All installations shall
be carried out in accordance with the locally applicable installation rules.
WARNING: Fuse (F1) should only be replaced by one of equivalent type and rating
1A (T) HRC 250V
WARNING: This camera is a Class 2 device and therefore does not have an earth connection
in the power cord. The leakage current on these cameras is well within safe limits. However, it is
advisable to connect the coaxial or RJ45-10 cable from the camera to the receiving equipment
(such as a monitor or matrix) before applying power to the camera, so that this small leakage
current has a low resistance path to earth.
