Please observe the following for wiring according to EMC guidelines:
Note!
ƒ
With 820X and 821X controllers, communication can be
impaired by electromagnetic interferences. For safe
communication, use an additional cable between the PE
connection of the basic device and the PE connection of the
communication module.
This is not necessary for all other controllers that can be used
together with the communication module.
ƒ
Differences in potential between the devices can be avoided
by using an equalizing conductor with a large cross-section
(reference: PE).
ƒ
Separate control cables from motor cables.
ƒ
Connect the data cable shields at both ends.
ƒ
Please see the information on wiring according to EMC
guidelines in the Operating Instructions for the basic device.
