Units with terminals for connecting external control voltage (G307) and without
optional auxiliary control voltage transformer
Connect the external auxiliary power supply for the drive control circuitry to breaker
Q11. See section
Auxiliary circuit current consumption
consumption of the circuitry.
Connecting the control cables for the supply unit
The supply unit is controlled using the operating switch and optional reset and
emergency stop buttons (G331) mounted on the cabinet door. No additional
control connections are used or needed. However, it is also possible to
• halt the supply unit by an external emergency stop button (if the unit is equipped
with a local emergency stop button, external buttons can be connected in series)
• read a fault indication through a relay output.
Note concerning oC139,
+C140 and +C141:
If relay output RO2 is used for on/off control of the optional
liquid cooling unit, the fault indication is not in use. See page
• communicate with the unit through a serial communication interface.
The standard I/O connections are presented under section
, page
. Refer to the circuit diagrams delivered with the
drive for the connection terminals for the external control devices.
