Connecting to a screw compression type terminal

Use a screwdriver with slot size 3,5 mm.

1.

Open the terminal before inserting a wire.

2. Insert the wire in the correct terminal.

3. Close the terminal and secure the wire with torque 0,7 Nm ±0,1.

Connecting to a push-in type terminal

1.

Press the actuating lever.

2. Insert the wire in the correct terminal.

3. Release the actuating lever.

Wire properties

Wire area, screw compression type connection block

Wire with crimp sleeve, ferrule or single solid conductor. Two wires with the same area must be used. Wire strip length 6,5 mm ±0,5.

Minimum 1x24 AWG and Maximum 1x12 AWG

Minimum 1x0,2 mm 2 and Maximum 1x3,3 mm 2

Minimum 2x24 AWG and Maximum 2x16 AWG

Minimum 2x0,2 mm 2 and Maximum 2x1,5 mm 2

Wire length

The maximum wire length is dependent on the wire voltage drop from the voltage source to the safety relay input terminal. It is crucial to fulfill "Minimum input high voltage (VIHmin)" requirement at "Maximum current sink (Isink)". Isink is typical 2.8/VR where VR is the voltage level measured at the R input terminal. Consult the section for technical data for technical characteristics.
