These requests for electromagnetic compatibility are fulfilled by all modules of :$*2Ç,￿2Ç6<67(0￿(except for 750-630 and 750-631).

7.5Power supply

If non-stabilized power supply is used for the supply of the buscoupler, it must be

stabilized by a capacity ( 200 µF per 1 A load current).

For the :$*2Ç,￿2Ç6<67(0￿a filter module has been developed (288-824).

This module serves as a filter module for non-stabilized 24 V DC power supplies if the specified voltage deviation is not met.

Reasons for the deviations may be voltage jumps in the primary circuit, overloads in the secondary circuit or the switching of undampened inductances and capacitances.

7.6Certificates

The modules of :$*2Ç,￿2Ç6<67(0￿ have passed the conformance test of UL. Look for listing mark on product.

The Profibus coupler 750-301 and 750-303 are certified of PNO with Z00241 and Z00242.

The Interbus coupler 750-304 has passed the relevant tests in accordance with the Interbus conformance requirements (number 111).

The DeviceNet coupler 750-306 has succesfully passed through the conformance test of Open DeviceNet Vendors Association Europe.
