Connecting Relay 1 and Relay 2

If you are using a multifunction relay, always connect it as follows:
Switching behavior of the slaves
In case of a fault, the multifunction relays of the slaves switch less reliably than the multifunction relays of the masters.
In case of a fault, the slaves wait for the master to confirm the fault.
Additionally required material (not included in the scope of delivery):
☐ Suitable bootlace ferrules if using stranded wire
Requirement:
☐ The technical requirements of the multifunction relay must be met (see Section 10 "Technical Data", page 101).
☐ Copper wire
☐ Conductor cross-section: 0.2 mm² to 2.5 mm²
Procedure:
1. Break through a suitable location in the cable feed-through plate with a sharp object.
2. Strip off the insulation from the cable and press bootlace ferrules onto the insulated conductors.
3. Lead the cable through the hole in the cable feed-through plate into the Sunny Island.
