IP 266 Installation Guidelines
3 Installation Guidelines
3.1 Safety Requirements
It is absolutely essential to the overall safety concept that the switching elements
discussed in the following be installed and matched to your system.
• EMERGENCY STOP switch for shutting down the entire system.
• Hardware limit switches for restricting the traversing range.
These switches initiate a preprogrammed deceleration procedure, and can be
connected as NC or NO contacts to the IP 266's digital inputs.
• EMERGENCY limit switches for a direct shutdown of the power section. These
switches are not reached until the hardware switches have been overrun.
W A R N I N G !
The failsafe switches for the power section must be designed as NC contacts
(e. g. failsafe shutdown in the event of a wirebreak).
