INSTALLATION INSTRUCTIONS
See Figure 1
1. Turn “OFF” and lock out the power to the equipment in which the AFCI/GFCI is to be
installed.
2. Move the handle of the breaker (A) to the “OFF” position.
3. Engage the back of the AFCI/GFCI with the mounting tabs in the panelboard. For the plug
in type, push down firmly on the front end to engage both the line terminal stab and neutral
terminal stab.
4. Strip insulation off load wires to a length of 3/8 in.
5. Connect load neutral wire (D) into terminal (H) and load power wire (E) to terminal (I) as
shown in Fig.1.
Ensure that wire connectors are properly torqued to 25 lb in.
To be installed only in Siemens Plug-On Neutral Enclosures.
TESTING INSTRUCTIONS
1. Turn on power to load center or panelboard.
2. Turn “ON” the AFCI/GFCI handle.
3. Press blue test button (F) as shown in Fig.1.
The AFCI/GFCI breaker is functioning properly when:
1. The circuit is interrupted.
2. The handle moves to the tripped center position (G) as shown in Fig.1.
LEDs (J,M) are used to indicate the last know trip condition.
Note: Test every month
TROUBLESHOOTING
Problem:
AFCI/GFCI does not trip after pressing the test button.
Possible C
ause
Solution
Panelboard is
not e
nergized
Ch
eck to ensure that the panelboard
is energized.
The circuit breaker handle is in the “OFF” position The circuit breaker handle must be in the “ON” position.
The circuit breaker is in the tripped position Reset the circuit breaker by switching the handle to the “OFF” position and then to the “ON” position.
Panel neutral (terminal) is not connected to the
neutral bus bar
Check that the load power wire, panel neutral (terminal) wire and load neutral wire are properly
connected.
Problem:
AFCI/GFCI trips immediately after the AFCI/GFCI or a connected device has been turned on.
Possible Cause Solution
The arc-fault circuit interrupter is not wired
properly
.
Check that the load power wire, panel neutral (pig- tail) wire and load neutral wire are properly
connected. A qualified electrician should make the repairs.
Short-circuit
If the AFCI/GFCI trips when a device is turned on, remove the device from the circuit and turn the
AFCI/GFCI on. If the AFCI/GFCI does not trip this would indicate a short in the device. A qualified electrician
should make the repairs.
AFCI/GFCI does not have a dedicated neutral Check wiring to ensure that there are no shared neutral connections.
AFCI/GFCI does not have the correct neutral Check wiring to ensure the load power wire and load neutral wire are from the same branch circuit
A ground-fault condition exists
A quick way to check for ground-fault conditions is to substitute a GFCI circuit breaker in place of
the AFCI/GFCI. If the GFCI trips, then you have a ground-fault condition. A common ground fault
is a grounded neutral, which may only cause a trip under load. This occurs when the neutral
conductor contacts a grounded conductor, so check your junction box and fixture connections.
An arc-fault condition exists Reset the circuit breaker by switching the handle to the “OFF” position and then to the “ON”
position. If the AFCI/GFCI trips again, call a qualified electrician to make the repairs.
Problem: AFCI/GFCI trips after it has been turned on, but not immediately
Possible Cause Solution
The arc-fault circuit interrupter is not wired
properly.
Check that the load power wire, panel neutral (pig- tail) wire and load neutral wire are properly
connected.
A qualified el
ectrician should make the repairs.
Overloaded circuit There are probably too many devices plugged into the circuits and overloading the AFCI/GFCI.
An arc-fault condition exists Reset the circuit breaker by switching the handle to the “OFF” position and then to the “ON”
position. If the AFCI/GFCI trips again, call a qualified electrician to make the repairs.
If solutions do not work, the AFCI/GFCI circuit breaker must be replaced.
AFCI/GFCI will need to be replaced if the following conditions are displayed by the yellow LEDs
LED (J): Blinking
LED(M): Blinking
LED Indication Guide (after recent trip has occurred)
Turn AFCI/GFCI to “ON” position
Observe LED indications and compare to chart at right:
LED indications will appear for 5 seconds each time the AFCI/GFCI is turned “ON”
LED display will appear each time the AFCI/GFCI is reset up to 30 days after last trip.
The last known trip condition can be cleared by the following process:
1. Turn the AFCI/GFCI to the “OFF” position.
2. Press and hold the PTT button.
3.
Turn the
AFCI/GFCI
to the “ON
” posi
tion.
