Safety

1.13 Electrical installation safety information

The electrical connection may only be performed by authorized specialist personnel according
to the electrical plans.
Comply with electrical connection information in the manual. Otherwise, the electrical protection
class can be affected.
The secure separation of contact-dangerous electrical circuits is only guaranteed when the
connected devices fulfil the requirements of the DIN EN 61140 (VDE 0140 Part 1) (basic
requirements for secure separation).
For secure separation, run the supply lines separated from contact-dangerous electrical circuits
or additionally insulate them.

1.14 Operating safety information

Warning - risk of injury!
Note that the actuator position may be changed accidentally by the repelling power of the
valve when the brake is released!
Make sure that process forces are not exerted on the thrust rod.
Before switching on, ensure that the specified environmental conditions in the "Technical Data"
chapter or data sheet are complied with and that the power supply voltage corresponds with the
power electronic unit.
When there is a chance that safe operation is no longer possible, put the device out of operation
and secure against unintended operation.
When mounting the actuator in areas which may be accessed by unauthorized persons, take
the required protective measures.
Switch off the power supply to the motor prior for manual operation.

1.15 Maintenance safety information

Switch off the supply voltage for the power electronic unit and, if necessary, disconnect the
separately supplied anti-condensation heater (option) when working on the actuator or related
subassemblies and take precautions to prevent unintentional switch-on.
