Product overview
Power-Fail-Signal Connection
The UPS modules can also be used to supply other bus couplers. To use the UPS module with the bus
coupler the power supply has to be connected with the UPS. The power supply for the bus terminals has to
be connected seperaty. This depends on the terminal bus load. The Power-Fail connection should be
connected to a digital input terminal. (see picture below)
In case of power failure the UPS module rises the POWER-FAIL signal. The PLC program reads the input
via the terminal bus and can shutdown the application. In this mode the control of the UPS module is
controlled by the torque switch at the front side of the module.
