3412 Customer Connection Box Right-side view of control panel with side cover removed (61) DC compartment (62) Heater Contactor (HC) (optional) (63) Fuses (64) AC compartment | |
The DC compartment (61) contains the customer connections that are used for remote signals such as the general alarm output, generator running contact or the interconnections for the remote annunciator. The AC compartment (64) is used to house the AC fuses and controls for the optional space heater, optional engine heaters and the optional fuel transfer pump. The AC compartment (64) is also the place for customer interconnections of the AC supply to power these optional AC devices.
