Safety instructions

WARNING
Risk of injury due to live parts!
Risk of death or serious injuries due to electricity and
unexpected machine movements. In automatic mode the
motor is always under power, even at standstill.
• When working on the actuator or the related subassembly,
switch off the supply voltage for the electronic unit and
separate anti-condensation heater (option), and take
precautions to prevent unintentional switch-on.
The electrical connection may only be established by authorized
specialist personnel.
Notices on electrical connection in this instruction must be
observed; otherwise, electric safety and the IP-rating may be
adversely affected.
Safe isolation of electric circuits which are dangerous if touched
is only guaranteed when the connected devices fulfill the
requirements of EN 61140 (basic requirements for secure
separation).
To ensure safe isolation, install supply lines so that they are
separate from electrical circuits which are dangerous if touched,
or implement additional isolation measures for them.

General

Each actuator requires a suited Contrac electronic unit with
installed actuator-specific software. Observe the information in
the operating instruction. The specifications on the name plates
of the electronic unit and actuator must match to guarantee
correct hardware and software allocation.
