7.2 Disconnectors
Provide a suitable disconnector for the supply
voltage in the building installation in order to de-
energize the device from current and voltage.
·Install the disconnector near the device in a
location that is easily reachable for the user.
·Mark the switch as a disconnecting device for
this device.
7.3 Supply voltage
A supply voltage is required for operation of the
device. The type and level of the supply voltage
for your device can be found on the rating plate.
The connection of the supply voltage is made via
the plug-type terminals on the rear side of the
device.
Before connecting the supply voltage, ensure
that the voltage and frequency correspond to the
specifications on the rating plate.
Connect the supply voltage via a UL/IEC-
approved fuse.
After connecting the supply voltage, a display
appears. If no display appears, check:
·the connection of your device.
·the supply voltage.

WARNING
Risk of injury due to electric voltage!
Serious personal injuries or death can occur
due to:
·Touching live exposed or stripped cores.
·Device inputs that are dangerous to touch.
Before starting work, disconnect your
system from the power supply! Verify that
there is no current!
ATTENTION
Property damage due to noncompliance with
the connection conditions.
Noncompliance of the connection conditions
or exceeding the permissible voltage range can
damage or destroy your device.
Before you connect the device to the supply
voltage, please observe the following:
·
The voltage and frequency must comply
with the specifications on the rating plate.
·
Observe the limit values as described in the
user manual.
·
In building installations, secure the supply
voltage with a UL/IEC-listed circuit breaker/
fuse.
·
The disconnect device:
-
must be easily accessible for the user and
located in the vicinity of the device.
-
must be labeled for the respective device.
·
Do not tap the supply voltage at the voltage
transformers.
·
Provide a fuse for the neutral conductor
if the neutral conductor connection is not
grounded to the source.
