The device must be connected to a power supply system with a proper earth system.
Moreover, it is recommended to protect power supply lines of the products from indirect
contact and / or shorting to earth by using appropriately sized anti electrical shock switch.
The electrical connection must be carried out by a qualified electrician. Ensure that the
mains frequency and voltage correspond to those for which the device is designed, as shown
in the electrical data label.
4.3 - CONNECTION TO THE DMX CHAIN
Use a cable conforming to specifications EIA RS-485: pole twisted, shielded, 120Ohm
characteristic impedance and low capacity(PROEL DMXD – DMXD1).
Do not use microphone cable or other cable with different characteristics than those
specified. Terminations must be made with male / female XLR 3-pin connectors. You must
enter on the last device a terminal plug with a 120Ohm resistance (min1 / 4 W) between
terminals 2 and 3.
IMPORTANT: The cables must not come into contact with each other or with the metal
housing of the connectors. The housing itself must be connected to the shield braid and to
pin 1 of the connectors.
