10.5. Electrical Installation (AS-i)
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.
