Mounting
4.1
Introduction
Before assembling the two components, the interface cables of the operator panel front (IO/USB
cable K1, K2 display cable and, if necessary, K3) must be inserted into the corresponding socket
of the TCU (visible behind the housing cut-out).
Electric shock in the event of an individual error when grounding is insufficient
If the device is installed in an environment with hazardous voltages with inadequate
grounding, this may cause an electric shock in the event of an individual error. This can result
in death, serious injury and material damage.
Adequately ground the conductive parts of the panel in accordance with the nationally
applicable regulations. When dimensioning the protective conductor connection, note the
fuse ratings of the electrical circuits with hazardous voltages, which would have an effect in
possible individual error scenarios.
Parasitic voltage
If the device is installed with inadequate insulation in an environment with higher/more
hazardous voltages, parasitic voltages may occur. This can result in death, serious injury and
material damage.
Insulate the cables appropriately for the highest voltage coming into consideration.
Note
Since some of the interfaces do not have a cable strain relief for the cables to be connected, it
is recommended to secure the cables to the u-shaped lugs on the supporting plate using cable
ties.
The safety of a system with an integrated TCU with operator panel front is the responsibility
of the system installer.
Observe all relevant information from this manual regarding the mounting of the chosen
operator panel front.
The mounting at the installation site is performed in accordance with the instructions of the
chosen operator panel front.
