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 (SAGITTER SG DMX3 – SG DMX5).
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.
