USING HIGH VOLTAGE POWER
The CCC5100H-7 and CCC5110H-7 cameras are designed to operate from a 120/240 VAC power source. Connect the nondetachable power cord
to a power source of 100-240 VAC ±10%, 47-63 Hz.
to a power source of 100-240 VAC ±10%, 47-63 Hz.
The operating voltage is clearly marked on the rear panel of the camera. On the power cord, the brown lead is labeled AC HI (HOT) and the blue
lead is labeled AC LO (NEUT). Protect the circuit with a 3 A fuse. Ensure that a secure means of isolation from the AC power is provided for the
camera in accordance with the national wiring regulations of the country of installation.

USING COAX VIDEO
The CCC5100H Series camera outputs coax video from either the BNC connector on the rear panel or through the multifunction connector.
The camera also supports two Pelco up-the-coax technologies.
The camera also supports two Pelco up-the-coax technologies.
Selected Pelco multiplexers and switchers send a Pelco V-Sync signal to the camera. The camera uses this signal to lock its vertical synchroniza-
tion pulse to all other connected cameras. This eliminates certain display problems at the head-end.

Pelco Coaxitron lets you access and configure the camera settings remotely from selected Pelco devices.
Connect a video cable to the BNC connector on the back of the camera. Refer to Table B for the type of video coaxial cable to use. If using the
multifunction connector, refer to

Video Coaxial Cable Requirements
*Cable requirements:
75 ohms impedance
All-copper center conductor; steel-center conductor cable may result in poor performance
All-copper braided shield with 95% braid coverage
All-copper center conductor; steel-center conductor cable may result in poor performance
All-copper braided shield with 95% braid coverage
WARNINGS:
•
Use 18 AWG (1.0 mm
2
) or larger wire to provide high voltage power to the CCC5100H-7/CCC5110H-7.
•
Do not connect high voltage power through the multifunction connector or you may damage the camera.
NOTE:
When connecting more than one camera to the same AC transformer, connect the same side of the transformer to the same
terminal on all cameras. Otherwise, the cameras may be out of phase, causing a vertical roll when switching between cameras. Refer to
Camera Synchronization
for more information.
