Note
Im
provement of interference immunity
• Lay signal cables separate from cables with voltages >60V.
• Use cables with twisted wires.
• Keep device and cables at a distance from strong electromagnetic elds.
• Take account of the conditions for communication specied in the Technical specications
(Page169).
Note
Conduit seals
Use appropriate conduit seals to maintain applicable IP and NEMA ratings.
Note
DC in
put terminals
The DC input terminals shall be supplied from a source providing electrical isolation between the
input and output, in order to meet the applicable safety requirements of IEC 61010-1. For
example, SELV source.
