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
energized.
·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 type and level of the supply voltage for your
device can be found on the
rating plate.
The supply voltage is connected via plug-in
terminals (scope of delivery) on the
front of the device.
Before applying the supply voltage, make sure that
the voltage and frequency match the specifications
on the rating plate.
After connecting the supply voltage, the display
becomes active.
INFORMATION
Note that the device requires an initialization
phase (boot time) at startup!
If no display appears, check:
·The connection of your device.
·The supply voltage.
ATTENTION
Material damage due to disregard of the
connection instructions!
Disregard of the connection instructions or
exceeding the permissible voltage range can
damage or destroy your device.
Before connecting the device to the supply
voltage, please note:
·
Voltage and frequency must correspond to
the specifications on the rating plate!
·
Comply with the limit values (see section
„19.
Technical data“ on page 96) as described!
·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
accessible 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.
