INSTALLATION

Precautions

Failure to observe the following precautions could

result in damage to the V-CCU.

 Make all connections to the V-CCU and associated

equipment with the input power removed. Check

and verify all connections before applying power.

Note: Spare pairs in multi conductor talkback speaker

cables, as are often used for classrooms, may be used to

distribute Valcom 2-wire digital clock correction signals.

DO NOT use spare pairs in any cable being used to

provide line level audio to one-way speakers, amplifiers,

or local sound mixers (i.e. VE9121 type devices). For

other scenarios, contact tech support before using spare

pairs for 2-wire digital clock correction. In addition, it is

advisable to maintain 8 inches of separation between the

cable carrying 2-wire digital clock correction signals and

all other low voltage cables.

V-C6124P Mounting Instructions

Locate an area on the wall capable of supporting the

weight of the power supply (approximately 5 pounds)

within six feet of an AC receptacle.

Using the two #8 screws enclosed, mount the

bracket to the mounting surface as shown

(See Figure 1).

Slide the V-C6124P onto the mounting bracket.

V-C6124P Wiring Instruction
