## **Wiring** 

][Verdrahtung_Si_unverzPlease note: 

- Information given in the “Technical details” must be followed. 

- Outputs 13-14, 23-24 are safety contacts. 

- To prevent contact welding, a fuse should be connected before the output contacts (see technical details). 

- Calculation of the max. cable runs lmax in the input circuit: 

   - ������ 

      - ����� 

      - ������� 

   - Rlmax = max. overall cable resistance (see technical details) Rl /km = cable resistance/km 

- Use copper wire that can withstand 60/75 °C. 

- Sufficient fuse protection must be provided on all output contacts with capacitive and inductive loads.

## **Installation** 

## **Dimensions** 

## ][Montage_PNOZsigma **Install base unit without contact expander module:** 

- Ensure that the plug terminator is inserted at the side of the unit. 

## **Connect base unit and PNOZsigma contact expander module:** 

- Remove the plug terminator at the side of the base unit and at the contact expander module. 

- Connect the base unit and the contact expander module to the supplied connector before mounting the units to the DIN rail. 

## **Installation in control cabinet** 

- The safety relay should be installed in a control cabinet with a protection type of at least IP54.

- Use the notch on the rear of the unit to attach it to a DIN rail (35 mm). 

- When installed vertically: Secure the unit by using a fixing element (e.g. retaining brakket or end angle). 

- Push the unit upwards or downwards before lifting it from the DIN rail.
