AS Interface - Design
12.8 Electrical installation of the AS interface
InternalcablingworkisnotrequiredforanyoftheASInterfacedesignswithmulti-poleconnection,which
makesinstallationandstart-uponsiteconsiderablyeasierandquicker,reducingtheriskofleaks.
However, you will require the correspondinglyassembled cable sets with the following pin assignments.
Likewise,thejumpersontheelectronicmodulemustbesetcorrespondingly(seeguresbelow).
NOTE!
Use of the control head in a potentially explosive atmosphere
` Onlyusecablesandcableglandswhichareapprovedfortherespectiveapplicationareaandtthe

` Close all unnecessary openings with lock screws/plugs approved for explosions area!
