• Screw the relay unit to the wall and tighten the screws. The "UP" arrow must
point to the ceiling.
• Cut the wires to a suitable length and remove the insulation on the first
6–7 mm. Take care not to damage the conductors.
Use a suitable wire size for currents of up to 8 A (1–2.5 mm
Silicon-coated cables are recommended. Rigid cables may break.
For best results, use flexible cables. All (non-rigid) wires must be
equipped with a wire ferrule. Check the crimped wire ends. All the
wires on each cable must be enclosed by the ferrule to ensure that
the entire cable is secure. The length of the contact area on the wire
ferrule should be 6–7 mm.
• Determine which cables to connect. Connect the COM output to the phase
wire and the NO or NC output to the neutral wire via the resistive load. Select
the correct output for your connected appliance.
