7.2
Ground wire connection
Use a ring cable lug to connect the protective
conductor to the device.
7.3
Circuit breaker
When installing the device in a building, provide a
suitable circuit breaker in order to disconnect the
device from the power supply.
·Install the circuit breaker near the device and
within easy reach of the user.
·Mark the switch as an isolation device.
7.4
Supply voltage
WARNING
Risk of injury due to electrical voltage!
Severe bodily injury or death can result from:
·Touching bare or stripped leads that are ener-
gized.
·Device inputs that pose a hazard when
touched.
·Disconnect your system from the power supply
before mounting and connecting the device!
·Secure it against being switched on!
·Check to be sure it is de-energized!
·Ground and short circuit!
·Cover or block off adjacent live parts!
A supply voltage is required to operate the device.
The level of the supply voltage for your device can
be found on the rating plate.
Before applying the supply voltage, make sure
that the voltage and frequency match the specifi-
cations on the rating plate.
The supply voltage must be connected via the
plug-in terminals on the rear of the device.
Connect the supply voltage via a UL/IEC ap-
proved fuse.
ATTENTION
Material damage due to disregard of the con-
nection instructions!
Disregard of the connection instructions or ex-
ceeding the permissible voltage range can damage
or destroy your device.
Before connecting the device to the supply volt-
age, please note:
·Voltage and frequency must correspond to the
specifications on the rating plate!
·Observe the limit values as described (see sec-
tion „15. Technical data“ on page 102)!
·In the building installation, secure the supply
voltage with a UL/IEC listed line circuit breaker/
fuse!
·Observe the following for the isolation device:
- Install it close to the device and easily acces-
sible for the user.
- Mark it for the respective device.
·Do not tap the supply voltage from the voltage
transformers.
·Provide a fuse for the neutral conductor if the
neutral conductor terminal of the source is not
grounded.
INFORMATION
The fuse is a line protection - it is not a device
protection!
