Table 2. Definitions of terms used in this guide.
1–4 Test Selection
The Test Kit can perform three types of tests on Trip
Units:
•Function tests verify the operation of the Trip Unit,
including:
–Time-overcurrent tests, both trip and no-trip
–Switch-setting verification (Power+, RMS-9 and
Epic only)
–Trip Unit self-test report
•High-current tests monitor the functioning of the Trip
Unit during primary current-injection testing of the
breaker with a separate, commercially available high-
current test set. Under high-current tests, the Test Kit
can temporarily suppress or defeat Ground Fault
protection. The Test Kit monitors the time at which
the Trip Unit goes into overcurrent pickup and
displays the overcurrent condition and the time
required to trip.
•Quick test verifies that the Trip Unit and the breaker
mechanism can cause the breaker to trip by actually
tripping the breaker.
The tested functions are listed in Table 3.

The current continues to ramp up until either one of the
function keys is pressed or 15.00C (or 15.00S for Ground
Fault) is reached. In either case, the simulated current is
held constant and a message similar to the following is
displayed:
... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... .
Current = 15.00C (Press F3 to run test)
|– CONT –|– EXIT –|
Overcurrent test current display.
Pressing CONT (F3) starts the test and initiates a
countdown timer, which is displayed until the Trip Unit
“trips”:
... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ...

command to the Trip Unit and activates the (flashing)
BREAKER TRIPPED LED.
Press MORE (F3) to return to the trip query display or EXIT
(F4) to return to the function test menu.
NOTE: The Pickup LED on Power+, RMS-9, and Epic
Trip Units is not lit and the Fault Trip annunciators do
not pop out during a time-overcurrent trip simulation,
since the Trip Unit is not actually experiencing an
overcurrent condition.
NOTE: Sur le déclencheur Power+, RMS-9, ou Epic, la
LED Pickup ne s’illumine pas et le temoin mécanique de
déclenchement ne sort pas pendant une simulation de
surcharge (à moins que le disjoncteur ne soit reéllement
dans ces conditions).
4–5 High-Current Primary Injection
The Test Kit can also monitor Trip Units during primary
current injection or “high-current” tests. While in monitor
mode, the Test Kit display indicates whether the Trip Unit
has “picked up” (detected an overcurrent condition) and,
if so, the type of overcurrent condition (Long Time, Short
Time, or Ground Fault). If the Trip Unit trips the breaker
while the Test Kit is monitoring it, the type of trip and
time to trip (the time between pickup and trip) are
displayed.
The Ground Fault function, if included, must be tempo-
rarily defeated when performing high-current primary
(single-pole) injection. The Test Kit can perform the
Ground Fault defeat function; a separate Ground Fault
defeat cable is not available.
Trip Unit Ground Fault Defeat
To initiate high-current testing, select HICURRENT (F2)
from the main test selection menu. The Test Kit first
verifies that it is connected to a Trip Unit with a digital
communication port; if not, the Digital Link Open
message is displayed. Press MORE (F3) at this point to
return to the main test selection menu.
If the Test Kit is connected to a Trip Unit with a
communication port, the HI CURRENT TEST LED is
activated and the Trip Unit options are checked. If the
Ground Fault option is installed, the Test Kit displays the
message:
... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ....
Defeat Ground Fault Protection?
|– YES –| |– NO –|– EXIT –|
Ground Fault defeat query.
If the Trip Unit under test does not have the Ground Fault
option, the Test Kit goes immediately to monitor mode.
If YES (F1) is selected in response the Ground Fault defeat
query, the Test Kit attempts to suppress the Ground Fault
option in the Trip Unit, after which it again checks the
Trip Unit options to ensure that Ground Fault protection
was defeated. If Ground Fault protection is still active, the
Test Kit displays the message:
... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... .
Ground Fault not defeated; try again?
|– YES –| |– NO –|– EXIT –|
Ground Fault defeat failure message.
Press YES (F1) to try again; press NO (F3) to send the Test
Kit to monitor mode. If Ground Fault protection is
successfully defeated, the Test Kit displays the message:

Press EXIT (F4) to return to the Trip Unit selection menu.
Trip Unit Pickup and Trip Monitor
When the Test Kit is in monitor mode, it displays the
message:
... ..... .Press F1 to exit when test is complete
|– EXIT –|
Monitor mode display.
While this message is displayed, the Test Kit is constantly
monitoring the status of the Trip Unit.
When the Trip Unit signals that it has entered pickup, the
Test Kit displays a message indicating the type(s) of
pickup, as in the illustration:
... ..... ...TU in pick-up: LT ST
|– EXIT –|
Sample Trip Unit pickup message.
The Test Kit continues to display the pickup message until
the Trip Unit signals that it is no longer in pickup.
If the Trip Unit initiates a trip, the Test Kit displays a
message showing the type of trip and the time to trip, as in
the example:
LONG TIME: CURRENT= 1.25C TIME= 575.75s
|– MORE –|
Sample display for Long Time trip.
Press MORE (F1) to return the Test Kit to monitor mode.
4–6 Trip Unit Quick Test
The Trip Unit quick test is a one-step test to verify that the
Trip Unit can trip the breaker. Since this test actually
causes the breaker to trip, suitable precautions should be
made before this test is performed.
Selecting QUICK (F3) from the main test selection menu
starts the TRIP TEST LED flashing and displays the
message:
... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... ..... .
Press F1 to trip breaker
|– TRIP –| |– EXIT –|
