Safety instructions

WARNING
Risk of injury due to live parts!
When the housing is open, contact protection is not provided
and EMC protection is limited.
• Before opening the housing, switch off the power supply.
WARNING
Danger due to electric current!
Danger of electric shock by residual voltage at the terminals
after switching off the power supply.
• Before opening the terminal compartment, switch off the
power supply and wait for > 2 minutes.
NOTICE
Damage to the device due to improper handling!
• When replacing the defective safety fuses, only fuses with
types and characteristics should be used (see Fuses on
page 39).
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.
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.
Instructions on the use of Error Current
Circuit Breakers (RCDs)
If additional protection against accidental contact due to the
use of an RCD is required by local regulations, the following
items should be observed:
• For the electronic unit EBS822, the use of a type B RCD is
not necessary, since from a design viewpoint, no voltage
levels > 60 V DC which can be dangerous upon contact
can occur.
• The use of a Type B RCD is recommended for the
electronic units EBS852 and EBS862.
• The operator is responsible for the correct layout of
additional protection against accidental contact due to
the use of an RCD!
