The wiring of electrical components for the start and
operation of refrigerant compressors is a typical task in the field of
refrigeration. Safety aspects also play an important role. With this knowledge
and these skills can be acquired. All components are operated and tested with
mains voltage to provide high relevance for practice. The electrical components
for the start and operation of the refrigerant compressor are arranged clearly
visible. The electrical connection of the individual components is made with
cables via the lab jacks. The components are e.g. the capacitor and start-up
relay necessary to start the motor. The circuit diagram on the front panel
enables the easy allocation of the individual components.
