INSTALLATION DIRECTIONS

Installation and maintenance must be carried out by specialized engineers only. Do not install the

components of the system in humid environments or near heat sources. Make sure that the power supplies

present in the system are not connected to the mains during the installation of devices. Before powering the

system, check that the cabling is correct. The wiring diagrams must always be followed (in case of different

applications contact Videx technical) and always use cables as outlined below. It is advisable to separate the

Mains lines (lift, electricity, electricity lock, etc.) from the BUS lines (A distance of at least 10 cm) to avoid

electrostatic discharge and magnetic influence that could cause problems to the on the system. It is also very

important to set all dip switches before powering up. If any are changed for any reason it is necessary to

power that device down and then back up for the change to take effect.

GUIDELINES TO OVERCOME EXTREME ELECTROMAGNETIC INTERFERENCE

In situations of EMI where interference is affecting the functions of the system it is advised to add the

following:

 Loop the mains cable twice through the ferrite core (Model No. RT310-190-160 or

equivalent).

 Loop the bus cable which connects the video distributor to the videophone

twice through the ferrite core (Model No. RKCF-13-A5 or equivalent)
