This option uses the digital input 5 (-XD2:15).
The requirements:
•
The option board OPTBJ
•
+CAPD 24 VDC power supply
•
+CAPU Auxiliary AC supply terminals or +CAPT Auxiliary voltage transformer
CAUTION!
The delay of the safety relay is process/machine-dependent. The designer and the
user of your system are responsible for understanding and setting the delay of the
safety relay. An incorrect delay can cause damage to the equipment.
+CPSB: EMERGENCY SWITCH OFF
The Emergency switch off function uses an input contactor to disconnect the drive from
mains. Pushing the emergency stop push button on the control compartment door opens the
control circuit of the input contactor.
The requirements:
•
+CICO Input contactor
•
+CAPU Auxiliary AC supply terminals or +CAPT Auxiliary voltage transformer
+CPIF: INSULATION MONITORING
With this option it is possible to monitor the insulation level in an IT supply network with an
insulation monitor in the control compartment. The insulation monitor supervises the supply
and the insulation faults in the output network.
The requirements:
•
+CAPD 24 VDC power supply
•
+CAPU Auxiliary AC supply terminals or +CAPT Auxiliary voltage transformer
+CIFD: AC FUSES AND FUSE SWITCH
When you have this option, you can isolate the drive safely from the mains with a fuse switch
that is located directly below the power unit.
With the enclosure size MR12 and the input contactor +CICO, the fuse switches are located in
the additional cabinet section. The fuse switches have overtemperature protection by means
of a thermostat. When the temperature limit of the thermostat is reached, a safety circuit
opens and an external fault occurs. The function uses the terminals +24 Vout (-XD2:12) and
digital input 4 (-XD2:14).
The wiring of the option can be seen in chapter 5.1.1 Main circuit diagrams of the cabinet.
