Terminal assignment:
Terminal Switching output
X703:1 DO 1
X703:2
X703:3
X703:4 DO 2
X703:5
X703:6
Requirement:
☐ The contactor must be suitable for connection to multifunctional switching outputs (see Section 11 "Technical
Data", page 51).
Cable requirements:
☐ Conductor cross-section: 1.5 mm² to 2.5 mm²
☐ Conductor material: Copper
☐ Maximum cable length: 30 m
Procedure:
1. Insert the cable (see Section 9.1 "Inserting the Cables", page 47).
2. Strip the cable.
3. Strip 15 mm to 18 mm of the insulation from the insulated conductors. When doing so, ensure that no pieces of
cable fall into the enclosure.
4. Connect the insulated conductors to the terminals X703:1 to X703:6 in accordance with the customer-specific
system circuitry. If the conductors are stranded wires, additionally pretension the springs of the spring-cage
terminals using a screwdriver (see Section 9.2 "Connecting the Stranded Wire to the Spring-Cage Terminal",
page 48).
5. Ensure that the insulated conductors are firmly in place.
