Controlled Outgoing Circuit For Auxiliary Equipment 400 V 3 Ac (Option N30) - Siemens SINAMICS GM150 Operating And Installation Instructions

Description
3.6 Description of options
Switching the circuit-breaker off
The circuit-breaker is opened under the following conditions:
● After a normal "off command".
● By two OFF commands via LA - K32 and LA - K33, if one of the following switch-off
If the motor circuit-breaker MA - Q11 trips, an appropriate warning is issued.
The capacitor release supplies the auxiliary voltage for switching off the circuit-breaker several
minutes after failure of the input voltage.

Controlled outgoing circuit for auxiliary equipment 400 V 3 AC (option N30)

This option includes a controlled outgoing feeder for external auxiliaries (3 AC 400 V, max.
4 KW). The controlled outgoing feeder is protected by a circuit breaker. The circuit breaker
setting range is cos phi = 0.8 (7 A up to 10 A).
The option can be used to operate external fans on motors and pumps and oil supply units.
The "ON" command at the drive closes the contactor. The "OFF" command opens the
contactor.
Externally provide the necessary drive power supply. The terminal assignment is provided in
the circuit diagram of the drive.

If the "OFF feedback" from the circuit-breaker is not received via terminal LA - K32 and
terminal LA -X52:9 within the deactivation monitoring time. The output voltage (capacitor
voltage) of the release is then applied to the OFF coil of the circuit-breaker via LA - K33
and terminal X52:13.
conditions is fulfilled:
– One of the two voltage monitoring systems LA - A71 responds (block monitoring of the
power supply from the switchgear to terminal LA - X52: 7) or LA - A72 (monitoring of
the voltage provided to terminal LA - X52:14 by the capacitor release).
– Activation of "Emergency OFF commands" (EMERGENCY OFF button in the cabinet
door or via terminal strip).
– Tripping operation by the Power Stack Adapter after a serious fault.
