Safety notes
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!
NOTE: 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.
NOTE: 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.
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: Risk of automatic machine restart!
When using the manual reset function with
monitored start, the “cross-circuit between
S21/S22 and the cable from the reset button
to S34” error must be prevented by design-related measures, especially for safety functions with increased risk potential (see
EN ISO 13849-2).
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 persons.
Otherwise the warranty is invalidated.
