AS Interface - Design
11.7. electrical installation as interface
Internal cabling work is not required for any of the AS Interface designs with multi-pole connection, which makes
installation and start-up on site considerably easier and quicker, reducing the risk of leaks.
However, you will require the correspondingly assembled cable sets with the following pin assignments. Likewise,
the jumpers on the electronics module must be set correspondingly (see figures below).
note!
use of the control head in explosive atmosphere
Only use cables and cable glands that are allowed for the respective application area, and mount the cable
•
gland according to the respective operating instructions!
Close all unnecessary openings with lock screws/plugs approved for explosions area!
