SIMOVERT MASTERDRIVES
The 9-pole terminal strip is used for connecting up a 24 V voltage
supply and for connecting up a main or bypass contactor and for the
"Safe STOP" function.
The voltage supply is required if the inverter is connected up via a main
or bypass contactor.
The connections for the contactor control are floating.
The "Safe STOP" function ensures that no rotating field can occurr at
the motor terminals, i.e. the motor cannot rotate. By opening the jumper
between terminals X9.5 and X9.6 (through an external contact), the
"Safe STOP" function is activated. The inverter is delivered with
jumpered terminals X9.5 and X9.6.
