2. 2 Safety Measures
When electrical devices are in operation,
certain parts of these devices are necessar-
ily subject to dangerous levels of voltage.
Serious bodily harm or material damage
may therefore result if they are not handled
properly:
c
WARNING!
Risk of injury from electric
voltage!
Serious bodily harm or death may result
from hazardous voltages.
For this reason, please note the follow-
ing:
• Before making connections, ground
the device on the protective earth ter-
minal, if available.
• Hazardous voltages can occur in any
of the circuits connected to the volt-
age supply.
• There may be hazardous voltages in-
side the device even after disconnect-
ing the voltage supply.
• Outfit single-wire leads with ferrules.
• Only connect screw terminals with the
same number of poles that are of the
same make.
• Before starting to work, de-energize
the system.
c
WARNING!
Risk of Injury from
Improper Use
If the device is not operated in accordance
with the documentation, safety is no longer
ensured and the device may pose a risk.
2. 3 Qualified Staff
This device is to be operated and maintained
only by qualified staff.
Qualified staff are people who are able to
recognize risks and avoid possible hazards
that the operation or maintenance of the
device may cause, based on their specialized
training and their experience.

3. 1 Input Check
Proper transport and professional storage,
installation and assembly, as well as careful
control and maintenance, are all precondi-
tions for the proper and safe operation of this
device.
Perform unpacking and packing with the usu-
al care and without the use of force, and only
use suitable tools.
Perform a visual inspection of the devices to
ensure a proper mechanical condition.
Check the delivery contents for complete-
ness before starting to install the device.
If it is to be assumed that safe operation
is no longer possible, the device is to be
placed out of order immediately and pro-
tected against unintended operation. It is to
be assumed that safe operation is no longer
possible if the device e.g.:
• shows visible signs of damage,
• no longer functions despite an intact pow-
er supply,
• has been exposed to longer periods of
adverse conditions (e.g. storage not con-
sistent with the admissible climate limits
without an adjustment of the room climate,
thawing, etc.) or transport stresses (e.g.
fall from a great height even without any
outward visible signs of damage, etc.).
3. Intended Use
CATTENTION!
All of the screw terminals included in
the delivery contents are connected
to the device.
CATTENTION!
All of the delivered options and
design variants are described on the
delivery note.
3. 2 Intended Use
The device is:
• intended to be built into control cabinets
