2.2 Grounding diagram
In order to ensure a safe diversion of electric interferences,
the following points have to be observed:
• Connect the device and the switch cabinet with a central grounding
point via the shortest route possible.
• Make sure the connection between the device and switch cabinet
has the lowest inductivity possible.
• All the data cables connected to the device must be shielded cables.
• The shields must be grounded on both the ends. Connections
between systems must be of low impedance. High transient currents
over the line shield resulting from differences in potential must be
excluded.
• The design of the grounding connection with green/yellow cable must
have a cross section of at least 4 mm².
2.3 Installation
Installation The device should be installed in an HF-proof housing or switch cabinet
made of metal.
To ensure that heat generated in the device can dissipate into the
environment, a space of 100 mm must be maintained around the device!
Eight hexagon nuts are used for assembly (depending upon execution of
the equipment).
Tip!
The equipment may not be inserted lying, since otherwise convection at
the radiator box is not ensured. Max. inclination to the rear 20°.
Caution!
Potential hazard of damaging the device!
Front-side protection type IP65 is only guaranteed if the seal is correctly
seated in the front plate.
