Control connections of supply module

4.2.1. Overheat of internal brake resistor (9210 X1)

The thermal contact (capacity 230V/10A) of the internal brake
resistor can be accessed via the connector X1 of the supply
module. It can be used to switch off the mains in case of overload
of the internal brake resistor (see also: External brake resistor).
Caution!
Unlike previous models of this series, the connector X1 of the supply module does
not have to be bridged any more. This connector cannot be used for the monitoring
of an external thermal contact and the like! To protect the inverter, wiring according
to figure "Wiring using the internal brake resistor" (page 19) is necessary.

4.2.2. Mains and DC-bus monitoring (9210 X3)

At X3 of the power supply module several signals are available,
that give information about the status of the mains. The wiring of
this terminal is not necessary to make the device work. If the
software feature mains failure with DC-bus controlling is required,
the terminals X3,1 and X3,3 must be wired. By using an external 24
V supply there is an optoisolated signal of mains failure at terminal
X3,5.
For further information see: Parameter setting, page 50.
