Safety notes
WARNING: Risk of electric shock
During operation, parts of electrical switching
devices carry hazardous voltages.
Before working on the switching device, dis-
connect the power.
Please observe the safety regulations of elec-
trical engineering and industrial safety and lia-
bility associations!
Disregarding these safety regulations may re-
sult in death, serious personal injury or dam-
age to equipment.
Startup, mounting, modifications, and up-
grades should only be carried out by a skilled
electrical engineer!
WARNING: Risk of automatic machine re-
start!
For emergency stop applications, the ma-
chine must be prevented from restarting auto-
matically 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 er-

In the event of an error, replace the device im-
mediately.
Repairs to the device, especially if the hous-
ing must be opened, may only be carried out
by the manufacturer or authorized persons.
Otherwise the warranty is invalidated.
NOTE: Risk of damage to equipment due

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.
NOTE: Risk of damage to equipment due
to noise emissions
When operating relay modules the operator
must meet the requirements for noise emis-
sion for electrical and electronic equipment
(EN 61000-6-4) on the contact side and, if re-
quired, take appropriate measures.
Only use power supply units with safe isola-
