WARNING

Risk of electric shock

During operation, parts of electrical switching devices carry 
hazardous voltages.
Before working on the switching device, disconnect the power.
Please observe the safety regulations of electrical engineering 
and industrial safety and liability associations!
Disregarding these safety regulations may result in death, 
serious personal injury or damage to equipment.
Startup, mounting, modifications, and upgrades should only be 
carried out by a skilled electrical engineer!

WARNING

Risk of automatic machine restart!

For emergency stop applications, the machine must be 
prevented from restarting automatically by a higher-level 
control system.
Protective covers must not be removed when operating 
electrical switching devices.

WARNING

Danger due to faulty devices!

The devices may be damaged following an error and correct 
operation can no longer be ensured.
In the event of an error, replace the device immediately.
Repairs to the device, especially if the housing must be opened, 
may only be carried out by the manufacturer or authorized per-
sons. Otherwise the warranty is invalidated.

CAUTION

Risk of damage to equipment due to incorrect installation

For reliable operation, the safety relay must be installed in 
housing protected from dust and humidity (IP54).
Carry out wiring according to the application.
Refer to the “Application examples” section for this.

CAUTION

Risk of damage to equipment due to noise emissions

When operating relay modules the operator must meet the 
requirements for noise emission for electrical and electronic 
equipment (EN 61000-6-4) on the contact side and, if required, 
take appropriate measures.
