Refer to Figures A-5, A-6, A-7, and A-8 for the DT3001
typical wiring diagrams. Note the following:
4.1 Direct wire connections to the terminal blocks must
be sizes #14 AWG to #10 AWG.
The appropriate sized spade and ring lugs can also
be used to accommodate the wires.
4.2 All contacts are shown in the de-energized position.
NOTE: The Protection Off Alarm Relay is energized
when control power is applied and the DT3001 is
operating properly. To obtain a contact that closes

contact that opens when protection is lost, use
terminals 46 & 48.
