2.2 Earthing scheme
In order to guarantee a safe derivation of electrical interferences, please
observe the following points:
• Please choose the shortest possible way to connect the appliance
and the switch cupboard to a central earthing point.
• Please pay attention to choose the connection with the lowest
possible induction between the appliance and the switch cupboard.
• All data-cables connected to the appliance have to be equipped with
closed lines.
• Please earth the screens on both sides. The connection between
the connected systems has to be of low impedance. Please eliminate
the transfer of high compensating currents via the conducting screen
due to differences of potential.
• Please earth the appliance with a green and yellow cable with a
cross-section of at least 4 mm².
2.3 Installation
Installation The appliance has to be installed into a HF-tight casket or switch cupboard
made of metal.
Please make sure that sufficient air can circulate. Please provide a space
for circulating air of 100 mm around the appliance, so that the heat
produced in the appliance can vanish into the surroundings!
When installing or dismantling the appliance, it must be stressfree.
When assembling the appliance in the casket, please do only use the
parts supplied with the appliance. Both kind and number of the assembly
parts depend on the appliance (cf. ratings).
Caution!
Damages at the appliance are possible!
The front protection IP65 is only guaranteed if the seal is attached correctly
to the front plate.
