INSTALLATION
When the cables go outdoor is mandatory to use shielded cables. The
cables’ shielding must be connected to the respective ground
connectors (-V).
For internal wiring without shielded cables is recommended an
electrical environment where the cables are well separated, even at
short runs, especially to the power cables or external cables which
can be essentially subjected to interference or lighting.
Use a twisted-pair cable for the contact cables. Make sure that the
cables correspond in size to the norms indicated in.
Max contact resistance = 25 Ohm
