For the system to meet full EMC compliance requirements, the following precautions
should be taken:
■ Screened power cable should be used.
■ The earth wire of power cables should be connected to the detector EARTH
terminal, and this in turn connected to an earth stud on the detector chassis.
■ All cables (power and signal) should pass through the screw-in metal cable glands
provided. The screen of the power cable should be terminated at the cable gland.
■ Power cables need to be fitted with a ferrite ring inside the detector case (2 off
provided). The 24V and 0V wires should be long enough to form a loop around
the ferrite wall.
■ Separate wires from the power cables should be kept as short as possible, just
enough to provide adequate stress relief.
Diagrams below show the appropriate arrangements for top and rear entry cables.
