RUN
When the mains voltage is non-standard, i.e. not selectable via the transformer tapping link
(380/415V, 220/240V or 110/120V), connect a low power Autotransformer to generate a
standard voltage. Connect the output of the Autotransformer to the AUX terminal. Move the
Supply Selector from "MAINS" to "AUX". Select the appropriate voltage via the transformer
tapping link. The Autotransformer must be connected to the same phase as the incoming
power to provide correct coding to the controller.
It is recommended that the "0V/common" be connected to protective earth/ground for safety
reasons. In a system comprising of more than one controller, the "0V/common" signals
should be connected together and joined to protective earth/ground at one point only.
Stall override link between terminals 14 and 15 required when using controller in current
control.
