Connect cables following the examples of wiring diagrams refer to the section
For connections,
In case the device connects a monitor / monitors powered from switching adaptors,
shall be carried out as described below:
Lay a trunk protective conductor with yellow-green insulation and copper wire cross-section of 1.5 mm from the main
protective conductor of the building to the last BK-4MVE device in the video circuit, which has connected monitors
powered from switching adaptors.
Connect the trunk protective conductor to the main protective conductor of the building.
protective
connected monitors powered from switching
adaptors to the trunk protective conductor (see the sections
and
Connection of the protective conductors is recommended to be carried out by means of a t-tap nylon insulated female
terminal and mating red nylon insulated male tab (for wires with cross-section from 0.5 to 1.5mm ). The male tab is
fastened to the protective conductor of the commutator by crimping. The procedure of connecting the protective
conductors is shown on Figure 4.
The t-tap nylon insulated female terminal and nylon insulated male tab are not supplied with the device. These parts
are available upon request.
