Before assembling the two components, the interface cables of the operator panel front must
be inserted into the corresponding base of the MCP (visible behind the housing cut-out).
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.
WARNING
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 device 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.
WARNING
Electric shock in the event of an individual error when the rear cover is missing
If the rear cover is missing when mounting the device in an environment with hazardous
voltage, a conductor with a hazardous voltage can come loose in the event of a normative
permissible individual error and touch parts of the printed-circuit board and cause electric
shocks. Due to its design, the printed-circuit board cannot trigger the overcurrent protection of
the circuit with hazardous voltage.
For this reason, protect areas of the printed-circuit board that are not adequately enclosed by
grounded sheet metal parts with a cover, when installed in an environment with hazardous
voltages. If this cover is made of conductive material, it must be safely grounded. See "Electric
shock in the event of an individual error when grounding is insufficient".
To avoid electric shocks, mount a rear cover on the device when installing it in an environment
with hazardous voltage.
WARNING
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.
