WARNING!
Risk of injury due to electrical shock!
Before reaching into the system (except for the
•
Teach-In procedure in a non-explosive atmosphere)
switch off the power supply and secure it to prevent
restarting!
Observe applicable accident prevention and safety
•
regulations for electrical equipment!
Risk of injury from improper installation!
Installation may be carried out by authorized techni-
•
cians only and with the appropriate tools!
Internal cabling work is not required for any of the AS Interface
designs with multi-pole connection. However, you will require
the correspondingly assembled cable sets with the following
pin assignments.
