4.2 – CONNECTION TO THE MAINS 
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.
