Protective insulation
Danger!
Dangerous electrical voltage
When one common voltage source is used for control voltages in separate
potential areas, the protective insulation between the separate potential areas
is deactivated.
Possible consequences:
ƒ The specified protective insulations are not complied with.
Protective measures:
ƒ Use independent voltage sources.
The available protective insulation within the controller of the "9400 Servo Drives" series
in accordance with EN61800−5−1 is implemented with a rated voltage for the external
conductor/star point of up to 300 V for mains with neutral earthing.
The following graphic representation
ƒ shows the arrangement of the terminal strips and the separate potential areas of
the controller.
ƒ serves to determine the relevant protective insulation between two terminals in
differently insulated separate potential areas.
