][Verdrahtung_Si_unverz_1Hi_unverzPlease note: 

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

- Outputs 13-14, 23-24, 33-34 are safety contacts, output 41-42 is an auxiliary contact (e.g. for display). 

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

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

- 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

- 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.

## **Notice** 

][Wichtig_PDBThis data sheet is only intended for use during configuration. Please refer to the operating manual for installation and operation. 

## **Service life graph** 

Lebensdauerkurve_Relais_Text vor KurveThe service life graphs indicate the Lkv **e** bnsda **ur** number of cycles from which failures fo}Oo due to wear must be expected. The oO wear is mainly caused by the electrical xog 10000 -SSa SS RS load; the mechanical load is negligible. 

> Lebensdauerkurve_Relais_Text nach Kurve_SIF Bsp **Example** 

- Inductive load: 0,2 A 

- Utilisation category: AC15 

- Contact service life: 2,000,000 cycles 

Provided the application requires fewer than 2,000,000 cycles, the PFH value (see technical details) can be used in the calculation. 

To increase the service life, sufficient spark suppression must be provided on all output contacts. With capacitive loads, any power surges that occur must be noted. With contactors, use freewheel diodes for spark suppression.

Technische Daten_Satz No. 

## No. stands for order number. 

Si-Kennzahlen_Zusatz_Relais_Lebensdauer_PDBIt is essential to consider the relay's service life graphs. The relay outputs' safety-related characteristic data is only valid if the values in the service life graphs are met. 

The PFH value depends on the switching frequency and the load on the relay output. If the service life graphs are not accessible, the stated PFH value can be 

used irrespective of the switching frequency and the load, as the PFH value already considers the relay's B10d value as well as the failure rates of the other components. 

All the units used within a safety function must be considered when calculating the safety characteristic data.
