A4.0 WIRING AND SETUP
ENSURE THAT THE INCOMING AC POWER
SOURCES ARE DISCONNECTED BEFORE
PERFORMING ANY WORK ON THE DIGITRIP 3001
PROTECTIVE RELAY OR ITS ASSOCIATED
EQUIPMENT. FAILURE TO OBSERVE THIS
PRACTICE COULD RESULT IN EQUIPMENT
DAMAGE, SERIOUS INJURY AND/OR DEATH.
Refer to Figures A-4, A-5, A-6, and A-7 for the DT3001
typical wiring diagrams. Note the following:
• 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.
• 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
when protection is lost, use terminals 48 & 50. For a
contact that opens when protection is lost, use
terminals 46 & 48.
•
The Digitrip 3001 comes with the zone interlocking
jumpers installed (terminals 13 to 14 and 15 to 16).
Leave these jumpers in place if zone selective
interlocking is not used. See Section A-5 below for
more information on this topic.
• The INCOM communications LED can be seen
through a hole in the outer chassis.
NOTE: All wiring must conform to applicable federal,
state, and local codes.
