5. When connecting the AC supply voltage, perform the following steps:
• Connect the insulated conductors to the connecting terminal plate -X300 in accordance with the circuit diagram
(see Section 11.2.1, page 51). Observe the correct terminal assignment and ensure that the insulation is not
trapped.
• If you choose a single-phase voltage supply, you need to bridge the terminals 1 and 2.
6. When connecting the DC supply voltage, perform the following steps:
• Connect the insulated conductors to the connecting terminal plate -X300 in accordance with the circuit diagram
(see Section 11.2.1, page 51). Observe the correct terminal assignment and ensure that the insulation is not
trapped.
• If you choose a single-phase voltage supply, you need to bridge the terminals 1 and 2.
7. Ensure that the cable is securely in place.
6.3 Connecting Digital Inputs and Outputs
Cable requirements:
☐ Conductor cross-section if a bootlace ferrule is used: 0.14 mm
2
to 1.0 mm
2
☐ Conductor cross-section if no bootlace ferrule is used: 0.14 mm 2 to 1.5 mm 2
Requirement:
☐ Provide for external strain relief.
Procedure:
1. Strip 8 mm off the cable insulation.
2. If you are using bootlace ferrules, crimp them.
3. Connect the cables to the connecting terminal plates -X700 and -X701 in accordance with the circuit diagram (see
Section 11.2.1, page 51). Observe the correct terminal assignment and ensure that the insulation is not trapped.
4. Ensure that the cables are securely in place.
