DANGER
Warning of dangerous electrical voltage!
Working on live electrical devices poses a considerable risk of deadly or
serious injuries!
If an actuator is open or operational, there is a risk of coming into contact
with live parts (e.g. with a tool or another thin object).
–
The electrical connection may only be established by a qualified electri-
cian.
–
Adhere to the regulations of the VDE (German Association for Electri-
cal, Electronic and Information Technologies) and to the regulations is-
sued by the local utility company.
–
Make sure that no bare wires protrude from the terminals to eliminate
the risk of electric shock or short circuits.
Important information!
Limit switches and auxiliary switches are not suitable as signal encoders
for safety-related controls!
Important information!
For installation within a building, a switch must be provided as a separator
according to DIN EN 61010-1 in order to disconnect the actuator before
carrying out maintenance or troubleshooting work.
–
The separator must be placed so that it is easily accessible to the
user
–
The switch must be clearly identified as a separator.
–
The separator must not interrupt the ground conductor!
–
We strongly recommend installing a lockable switch.
Before
–
switching the actuator on or off ,
–
changing any settings (e.g. rotational direction or swivel range) at the
actuator,
check whether these actions could cause any dangerous movements
within the machine/system or malfunctions of other assemblies!
