The power distribution module provides a significant advance in distributing power in a refrigerated case. Operating in conjunction with a Tuscan controller, the power distribution module’s six relays control the fused socket outlets.
The power distribution module simplifies the wiring of a refrigerated case. Mating connectors plug into the switched sockets to supply the liquid line valve or an electronic expansion valve, the suction line valve, defrost heaters, fans and case lights. The assignment of the sockets, shown in the diagram overleaf, may be modified by the controller’s bit switches — see the installation guide for the associated Tuscan controller.
A rotary two-position isolator switch on the side panel controls the supply to the relay contacts.
