AC Input/Output Wiring Instructions
NOTE: The CEPS-A can be field-wired in 3 distinct modes of operation. See “WIRING MODES” insert
sheet for further details.
#1) (FACTORY DEFAULT) NORMALLY-ON: The emergency lights connected to the CEPS-A will be ON at all
times, during both normal condition and power interruptions. This mode is set by connecting the #1 wire on the
red transfer switch to the utility input hot.
#2) NORMALLY-OFF: The emergency lights connected to the CEPS-A will be OFF until a power interruption, at
which time they will turn ON. This mode is set by capping off the #1 wire on the red transfer switch.
#3) NORMALLY-SWITCHED: The emergency lights connected to the CEPS-A can be switched ON/OFF
normally, until a power interruption, at which time they will turn ON regardless of switch position. This mode is
set by connecting the load side of a switch, time clock, or relay panel to the #1 wire on the red transfer switch.
Please note: Only one switch can be used per inverter. If multiple switches are needed, wire inverter as
NORMALLY-ON, and use LVS EPC relays. With EPC relays an unlimited number of switch legs may be used.
Contact tech support for further details 1-800-982-4587.
The CEPS must be installed by a qualified electrician in accordance with local, state, and NEC codes. AC & DC
Voltages are hazardous and care should be taken to follow all instructions. Prior to wiring AC connections, discon-
nect AC Input feed at relevant branch circuit breaker(s) and verify using proper voltage meter.
Always wear appropriate clothing when handling batteries and equipment, and use insulated tools.
1) Check that all input breakers are disconnected. Trip all output breakers using a flat screwdriver.
2) Check that knockouts on top of panel have been removed and conduits have been installed.
3) Bring AC Input conductors and AC Output Conductors through the appropriate conduits. Per
NEC, emergency output circuit should be installed in a dedicated conduit.
4) Connect AC Input conductors to wires labelled “120VAC Input” or “277VAC Input”
5) Connect AC Output conductors to wires labelled “120VAC Output” or “277VAC Output”
(277V MODELS 1000W & Larger ONLY): Take ACME XFR out of box and mount per instructions. Confirm
that it has been properly configured: X1 should be connected with X3. X2 should be connected with X4.
Connect one of XFR A wires in panel to X1&X3 in transformer (also labeled XFR A).
Connect other XFR A wire in panel to X2&X4 in transformer (also labeled XFR A).
Connect one XFR B wire in panel to H1 wire in transformer (also labeled XFR B).
Connect other XFR B wire in panel to H5 wire in transformer (also labeled XFR B).
NOTE: For 277V systems 1000W & Larger ONLY, the XFR B wire in the transformer which is connected to
the White with Blue Stripe (#4) XFR B wire in panel should be grounded, because it is the neutral output of an
isolation transformer. See transformer grounding instruction sheet provided.
6) Connect grounds for AC Input & AC Output to grounding wires provided. For systems larger than
1000W, NEC requires a grounding electrode conductor be installed from panel to grounding electrode.
7) Refer to battery wiring instructions.
8) Ensure that cabinet is securely fastened to wall and that no wires are loose or disconnected.
9) Ensure all connections & grounding have been made in workman-like & code compliant manner.

CEPS-A GFCI Troubleshooting
If the GFCI on the blue inverter is tripping, there are two things that can
cause this: a crossed neutral (dangerous) or inrush current (not
dangerous). This simple test will help you to determine which it is.
#1) Get an amp/current meter
#2) Measure the red OUTPUT wire coming out of the inverter. Write
down how many amps________
Measure the white/red stripe OUTPUT wire coming out of the inverter.
Write down how many amps_________
#3) The two amp readings should be equal (within 0.1A preferred). If it
is equal and GFCI still strips, proceed to step #4. If it is not equal, there
is a problem with your output neutral wiring. It needs to be a
dedicated neutral wire going out to your lights and cannot touch the
building neutral anywhere. Usually one of the emergency fixtures in
the field has been incorrectly connected to a normal building neutral
wire. As a result, some of your neutral current is returning to your
building neutral instead of your inverter neutral. This is a code issue
and if the imbalance is large enough it can also damage the inverter.
#4) If the currents are balanced please call tech support at 1-800-982-
4587 and reference this troubleshooting guide, they will assist with
next steps.
Note: The reset switch for the blue inverter is on the back right
side of the inverter. It is a 3 position rocker switch. You can
reach it by reaching around the black cord through the opening
in the metal side bracket and pressing the switch to the
middle(OFF) position, wait 5 seconds, then turn it back down
(ON).
You only need to use the reset when the three LED’s shown in
the left side of the picture are flashing or red. Normally they
should all be green.
If first light and last light are RED, indicates low battery.
Measure DC voltage on battery, it should be between 12.5-
13.8VDC.
