SK 41 Safety relay
6.

Mechanical attachment

The switching device must be professionally installed:
- In a dust and moisture-proof control cabinet or housing.
- In compliance with protection class IP54.
- Onto a 35 mm DIN carrier rail.
The switching device must not be installed in close proximity to strong sources
of heat.
The switching device may be installed in any position.
7.

Electrical commissioning

Connecting the supply voltage to the wrong terminals can destroy the switching
device.
7.1

Preconditions

• The switching device can be operated with 230 V (115 V) or 24 V.
• If operated using 24 V AC/DC, the voltage must comply with the requirements for functional extra
low voltage (FELV) with safety separation.
• Signal contact 31, 32 is only an auxiliary contact (signalling, indicating etc.) and must not be
integrated into the safety circuit.
• Any cables laid outdoors or outside the control cabinet must be protected accordingly.
7.2

Electrical connection

• Connect the 230V AC (115V AC) power supply to terminals A1, A2 or 24V AC/DC to terminals
B1 (+), B2 (-).
• Connect the sensing device to terminals X1, X2.
• Connect the safety circuit that is to be monitored to terminals 13, 24.
If­the­switching­contacts­are­routed­redundantly,­the­factory­fitted­bridge­between­terminals­14, 23
must be removed.
• Bridge terminals S11, S12 to enable manual reset (factory setting: autom. reset, S11, S12 unbridged)
and connect the reset button to terminals Z1, Z2.
Following successful commissioning, the safety output 13, 24 will be activated (relay contact "closed").
The relay contact 13, 24 will open if the sensing device is actuated and the alarm relay will actuate
in accordance with the operating principle of the relevant switching device used.
