6. Installation
6. 1 Disconnectors
During building installation, provide a suitable
disconnector in order to disconnect the
device from the current and voltage.
• Install the disconnector close to the device
so that it is easily accessible to the user.
• Label the switch as a disconnection
device.
6. 2 Supply voltage
The device requires supply voltage
to operate.
Before connecting the supply voltage, ensure
that the voltage and frequency correspond to
the details on the rating plate!
The connection lines for the supply voltage
must be protected using a UL-listed fuse or
a circuit breaker.

WARNING!
Risk of injury due to electric
voltage!
Severe bodily injuries or death can occur
due to
• touching bare or stripped wires that are
live,
• device inputs that are dangerous to
touch.
Therefore, note the following:
• De-energise your system before
starting the work!
• The inputs for the supply voltage are
hazardous if touched!

CAUTION!
Damage to property due
to not observing the
connection conditions
Failure to observe the connection conditions
can damage or destroy your device.
Therefore, note the following:
• Adhere to the specifications for voltage
and frequency on the rating plate.
• Connect the supply voltage via a fuse
in accordance with the technical data.
• Do not connect the supply voltage to
the voltage transformers.
