Description of the Emergency Off connection
Pins 47 and 48 of control plug X14 make it possible to
disable the output stage of the frequency converter via
the hardware. The power flow to the motor is then inter-
rupted.
The two pins must be connected to each other to ensu-
re proper operation.
If the two pins are to be monitored by the system control,
a floating (dry) contact must be available on the system
side; load carrying capacity: 42 VDC, 100 mA.
The contact used and the connecting cable must be pro-
tected against line supply voltage through double or rein-
forced insulation such that no hazardous contact line
supply voltage can be applied to pins 47 and 48 in the
event of a fault.
