8. WIRING
Proceed as follows :
• Separate base and cover
• Mount base on DIN rail and check that securing elements (5.
4) hold it firmly in place.
• Carry out wiring according to the diagram and in observance of the relevant regulations in force, and using cables of :
– 1.5 mm
2
for power and relay control outputs
– 1 mm
2
for sensors and remote control
– 1 mm
2
for C-Bus and C-Ring. For wire length limits please see technical data sheets T 021 and T 022
• Reposition the cover on the base / terminal block and fasten with the 4 screws supplied (5.
3).
• Check that voltage is correct and supplied by the dedicated auxiliary line, measuring it upstream of the protec-
tion (circuit breaker, fuse....).
• Power up the device.
You are advised not to insert more than two cables in a single terminal of the controller and if necessary to use external junction
boxes.
