or two 9-volt alkaline batteries (batterie s not supplied).
• Provides power to the trip unit for viewing and setting set-
points with less than 15% load on the breaker or if the
replaceable Trip Unit Battery needs replacing.
• Verification of metering (phase simulation)
• Ground Fault Testing with Ground Fault Trip Indication
• Trip test
• Temporarily disable the Ground Fault feature during single
phase breaker testing
1-2 Summary of Operation
The functions of the various switches and LEDs are as follows:
Power Switch
Pressing this button will pow er-up the tri p unit. Th e green
Power LED will indicate that power has been provided to the

has an associated red LED that indicates the state of the
switch. If the LED is illuminated, then switch is ON and firing the
flux shifter to trip the breaker.
Disable Ground Fault
Pressing this button will cause the trip unit GF protection to be
temporarily disabled. To enable the GF, the switch and
associated red LED must be turned off. The GF switch has
an associated red LED that indicates the state of the swit ch
(GF disabled when red LED illuminated).
WARNING: When using EntelliGuard Digital Test Kit to
defeat Ground Fault function of EntelliGuard Trip Units, the
ground fault protection of the trip unit will not be active.
Power to the breaker shou l d b e r e m o v e d p r i o r t o u s i n g t h i s
feature. Before applying load to the breaker, ensure that the
Disable GF LED is OFF or the Test Kit is disconnected from
the trip unit.
Failure to follow this procedure can result in deactivation of
the Trip Unit GF protection.

1.2 Summary of Operations, Continued
Ground Fault & Overload
Pressing this button will cause a trip either on the
Ground Fault or Overload protection. The switch has a red
LED that is ON when the switch is pressed. This feature will
store the trip event in the Event log and operate the bell
alarm, if available.
CAUTION: With the Phase Current enabled, the
EntelliGuard trip unit will not provide correct protection to
the system, which may result in a trip below desired levels.
Pow e r s h ou l d b e disconnected from the circuit breaker
prio r t o enter i ng Phase Current Mode.
Ensure that the Phase Current LED is OFF when in normal
operation. Failure to follow this procedure can result in
improper operation of the system.
Phase Current
By pressing this switch, the EntelliGuard trip unit
will display approximately 100A on each current phase. This
can be viewed on the trip unit LCD under METER menu. The
switch has a red LED that indicates the state of the switch
(LED On when Switch is ON).
