Isolation of
Electrical, magnetically and electromagnetic interference fields are
weakened by means of an isolation, one talks of absorption.
conductors
Via the isolation rail, that is connected conductive with the rack,
interference currents are shunt via cable isolation to the ground. Hereby
you have to make sure, that the connection to the protected earth conduc-
tor is impedance-low, because otherwise the interference currents may
appear as interference cause.
When isolating cables you have to regard the following:
• If possible, use only cables with isolation tangle.
• The hiding power of the isolation should be higher than 80%.
• Normally you should always lay the isolation of cables on both sides.
• With data lines always use metallic or metalized plugs for serial
• At stationary operation it is convenient to strip the insulated cable
• To fix the isolation tangles use cable clamps out of metal. The clamps
• Lay the isolation on an isolation rail directly after the entry of the cable in
Please regard at installation!
At potential differences between the grounding points, there may be a
compensation current via the isolation connected at both sides.
Remedy: Potential compensation line

Only by means of the both-sided connection of the isolation you achieve
high quality interference suppression in the higher frequency area.
Only as exception you may also lay the isolation one-sided. Then you
only achieve the absorption of the lower frequencies. A one-sided
isolation connection may be convenient, if:
- the conduction of a potential compensating line is not possible
- analog signals (some mV res. µA) are transferred
- foil isolations (static isolations) are used.

the isolation on the PIN 1 of the plug bar!
