Safety instructions for the installation of the "Safe torque off" function

The installation and commissioning of the Safe torque off" function must be
carried out by skilled personnel only.

All safety−relevant cables (e.g. control cable for the safety relay, feedback contact)
outside the control cabinet must be protected, for instance by a cable duct. Short
circuits between the single cables must be ruled out!

Wiring of the safety relay K

with insulated wire end ferrules or rigid cables is

absolutely vital.

The electrical reference point for the coil of the safety relay K

must be connected

with the protective conductor system (DIN EN 60204−1 paragraph 9.4.3). Only this
measure guarantees that the operation is protected against earth faults.
