Cables And Wiring - Elkron EL250RT Notice D'installation Et D'utilisation

9 CABLES AND WIRING

The wiring must be performed using two distinct cables.
The first (3x1.5 mm² electrical cable) supplies 230Vac to the transformer.
The second (minimum 8x0.22 mm² shielded cable) is for the transmission of alarm and tamper signals, as well as for
signalling abnormal conditions (fog, masking) and synchronization between the two columns.
Note: The shielding on this cable must be connected to the 13.8 Vdc negative in all the columns.
230Vac cable (column power supply) Synchronization + signal cable
The size of the cables depends on the consumption of the columns and cable resistance in relation to the distances involved.
