Connections & Installation

Cable Connections

Connect cables to the Ceiling Mount as described below.

1. Make a 90 mm diameter hole in the ceiling.

Diameter 90 mm

2. Remove the cover from the Ceiling Mount.

3. Pass the cables through the cover.

Make slits in the rubber cap on the cover as shown in the diagram below. Pull the cables through the hole in the ceiling and pass the cables through the slits.

Connector

Maximum diameter 31 mm

Tube

Maximum diameter 22 mm

33 mm or less

Drip-proof pipe

MEMO

The diameter of the cover hole without the cap is 20.5 mm. For dust prevention, remove the cap (side) and install a drip-proof pipe.

(Be sure to use a drip-proof pipe. The maximum diametre of the pipe connector is 31 mm.)

When distributing the cable from the side, use JVC’s WB- S573 ceiling direct-mount bracket. In this case, the length of the connector should be 33 mm or less, and the maxi- mum diameter of the tube should be 22 mm or less.

4. Connect the cables.

Connect the cables to the terminals on the Ceiling Mount. The four connections consist of a AC 24V power cable, a coaxial cable and a control signal cable.

Control signal cable

To a remote controller such as RM-P2580

To the monitor, etc.

Power cable

To the AC 24 V power supply

AC 24V power cable

This cable connects the AC 24V power supply to the AC 24V input connector. To prevent connection errors and disconnections, the use of lug plate for connections to the AC 24 V INPUT connector is recommended.

When a 2-conductor VVF (Vinyl-insulated vinyl-sheath ca- ble) is used, the maximum connection length is as shown below. (These are merely the standard reference values.)

CAUTIONS

When thin cables are used the cable resistance increases. As a result, when the power consumption of the unit is at its max- imum level (during the simultaneous operation of panning and tilting) the effective voltage will drop.

When the voltage drops while the camera is in use, perform- ance can become unstable and preset positions may not be reproduced accurately.

To prevent problems, either use thicker cables that have lower resistance or decrease the cable length by installing the power supply unit closes to the camera. Attempt to reduce the volt- age drop to less than 10% while the rated current level of the camera is flowing through the cable.

Do not connect an AC 24V cable directly to an AC 230 V outlet. This will cause damage to the unit.
