Foreword
Note
For IT and TT line supplies, the measuring equipment and programming
devices which are connected must be referred to the reference potential of the
module group.
Notice
M600 and M500 are not PE potentials. A hazardous voltage of between 300 ...
400 V with respect to PE is present at the terminals. These potentials may not
be connected to PE.
Warning
!
The "protective electrical separation" can only be guaranteed when compo-
nents certified for the system are used.
"Protective separation"
can only be guaranteed by ensuring the degree of protection of the system
components.
For "protective separation" the shield of the brake cable must be connected to
PE through the largest possible surface area.
"Protective separation" must be provided between the temperature sensor and
the motor winding of third–party motors.
Warning
!
Start–up/commissioning is absolutely prohibited until it has been ensured that
the machine, in which the components described here are to be installed, fulfills
the regulations/specifications of the Directive 89/392/EEC.
Warning

The information and instructions in all of the documentation supplied and any
other instructions must always be observed to eliminate hazardous situations
