The ILC Load Center provides the convenience of an all-
inclusive lightweight power center in a durable housing and
injection-molded faceplate. The ILC includes AC circuit
breaker positions, DC fuse panel, and DLS Series Converter
for providing practical accessibility and the level of power
you require.

LOAD CENTER OVERVIEW
I. LOCATION
The ILC should be mounted on an interior vertical surface
where there is sufficient depth to allow for space for the
panel and wiring behind it. Typical locations include under
counter cabinet fronts or sides, below closet compartments,
overhead cabinet fronts, and bed pedestals. Under floor
storage compartments in the back wall of closets are
not acceptable, as the panel must not be installed in the
rear of any storage compartment. Eye level locations are
best, where possible, as it is easier to reset or replace break-
ers or fuses.
The location chosen must have access space in front for
service after installation. This space is defined by the Na-
tional Electric Codes as 24″wide by 30″deep. However, if the
ILC is mounted facing the aisle, then one of these dimen-
sions may be reduced to 22″. Behind the wall, the converter
on the back of the ILC requires a minimum of 3 cubic feet for
45A models and 5 cubic feet for 55A models.
When choosing a mounting location for the ILC, consider-
ation should be given to its proximity to supply components,
such as powercord (or powercord/generator/inverter lines
from a transfer switch) on the 120 VAC side, and the bat-
tery/converter locations on the 12 VDC side. Where pos-
sible, consideration should also be given to mounting the
ILC toward the middle of the RV, thus equalizing the length
of the different 12 volt branch circuits, in order to minimize
DC voltage drop.This is preferred to circuits which must run
the entire length of the vehicle.
II. CABINET PREPARATION
Cut an opening in the face of the cabinet for the ILC. The
cabinet face must be strong enough to support the unit dur-
ing vehicle operation. Approximate dimensions for the open-
ing are 7 1/8″high and 12 3/8″ wide. If the opening is cut into
light paneling the opening must be framed with support
members into which Load Center mounting screws may be
driven and to which cables may be attached.
Determine how many branch circuits will be used. Remove
the rectangular knockouts for those branch circuits. Mount
the ILC in the opening on the cabinet using four screws.
III. 120 VOLT COMPARTMENT
Install an 8 gauge copper chassis ground wire to the Load
Center ground bar. A hole in the case is provided for wire
entry directly to the bar.
The ILC Series Load Center is a compact, attractive, elec-
trical distribution panel designed to handle the 120 volt AC
and 12 volt DC distribution of an RV or other similiar AC/DC
system.The 120 volt compartment is rated for 30 amps 120
VAC, and will accommodate from two branch circuits to a
maximum of one pole main and seven branch circuits. Stan-
dard configuration for an RV with 30 amp powercord is a 30
amp main and five branch circuits. Installations with greater
than five branch circuits require the incorporation of a listed
energy management system.The 12 volt compartment will
accommodate twelve circuits utilizing blade type fuses.The
panel is acceptable for Canada by utilizing optional bush-
ings in the 12 volt wire entry holes. It comes with a standard
Two-Year Warranty.

Powercord- (Fig A) Attach a cable clamp in the 1″round open-
ing for the supply wire (powercord, feed wire from transfer
switch, etc.) Attach and tighten the cable clamp nut as re-
quired. Remove outer sheathing from the supply wire, and trim
leads (recommended 1.5″ for the ground wire, and 2.5″for the
neutral and hot wires; see wire stripping guide, Fig. B). Strip
1/2″insulation from the ends of the lead. Insert the wire through
the clamp. Connect the green (ground) conductor to the first
terminal on the ground bar located toward the front of the com-
partment. Connect the white (neutral) conductor to the bottom
terminal on the neutral bar located at the rear of the compart-
ment. Tighten screws on cable clamp to secure supply wires. Do
not install circuit breakers until other connections are made first.
Branch Circuits- (Fig. C) Remove sheathing from nonmetal-
lic branch circuit wiring, and trim leads (recommended 1.5″ for
the ground wire, and 2.5″for the neutral and hot wires; see
wire stripping guide, Fig. B.) Strip 1/2″insulation from the ends
of the leads. Insert wires into rectangular openings; the sheath-
ing must intrude into the compartment 1/4″or more. Wedge-
shaped cable clamps can be provided for the ILC to secure
the branch circuit nonmetallic cables inside the box as re-
quired by the National Electric Code. If wedge clamps are re-
quired, contact Customer Service at 1-800-866-IOTA (4682).
Insert ground wire into the ground bar and tighten terminal screw.
Attach the neutral conductor to the neutral bar.Tighten securely.
The NEC allows only one conductor per terminal on the neutral
bar. Repeat this process with all the branch circuits.
IV. CIRCUIT BREAKERS
Install circuit breakers (Fig. D.). Connect black (hot) wires
to the circuit breakers.Tighten securely.The NEC allows
only one conductor per terminal in the circuit breakers.
NOTE: The Load Center is listed to accept any standard
1″wide circuit breaker if the interchangeable models cur-
rently on the market, whether one pole or twin. It is not
brand or part number specific. ILC-30 models are listed
for a 30 amp breaker as a main. The main breaker must
be secured in place by means of a hold-down clip.
V. 12 VOLT COMPARTMENT
The fuse panel will accommodate ATO/ATC sized blade
fuses. Install fuses or breakers of the correct amperage.
Proper protection may be either to protect wires of a cer-
tain size on a general purpose branch circuit, or to protect
individual appliances, such as a water pump or a TV an-
tenna booster, on a dedicated circuit. All wires connected
to the DC fuse panel extend out of the back of the ILC unit
and are labeled with the fuse position number for ease of
wiring.
CANADIAN REQUIREMENTS: Canada requires that all
12 volt fuses used in RVs be listed to CSA standards.
There is also a requirement in Canada that low voltage
panels be enclosed, “...such that an 1/8″diameter rod shall
not penetrate.” For Load Center installation in Canadian
RVs, snap the optional round bushings into the 12 volt

1) Turn on all circuit breakers in panel.
2) Make sure all power supplies including inverter and gen-
erator are off. If there are other power supplies present, and
they are electrically connected to the RV system by means
of a transfer switch, refer to the transfer switch hi-pot in-
structions before proceeding further. See Note.

wire entry holes; they may be installed from the outside or
inside.The pie-shaped fingers in the bushings bend to allow
wiring to pass, yet fill in the remainder of the space, com-
plying with Canadian requirements.
VI. LABELS
Install labels for 120 volt and 12 volt circuit identification.
Labels may be preprinted or blank labels may be filled in by
the installer. Labels must be visible after the deadfront is
attached. 120 volt labels are intended to be attached to the
circuit breaker. 12 volt labels are intended to be attached
above and below the fuse openings. Labels should not be
attached to the front cover, as the cover can be removed
and lost.
3) Turn off or disconnect all appliances that would be dam-
aged by the hi-pot test.
4) Connect the hi-pot leads to the powercord plug: one lead
to the hot and neutral prongs, the other lead to the ground
prong.
5) Energize the hi-pot and conduct test.This will hi-pot test
for leakage (short) between the current-carrying conduc-
tors and the ground in the entire RV 120 VAC circuitry. It
will also test the powercord itself. Turn off hi-pot.
6) If hi-pot test fails there is a short in the system.The next
step is to isolate the location of the short.Turn off the main
breaker in panel and hi-pot test again. If test fails, fault is
between the cord plug and the panel. Test cord for shorted
plug. If second test passes, turn on main breaker, and turn
off all branch breakers except one. Retest each branch
circuit individually until short circuit is isolated. Repair fault
and retest. Hi-pot test is successful when there are no more
fault indications.
NOTE: If the hi-pot test is performed from the plug on the
powercord, and there is a transfer switch present, the test
may only hi-pot the cord itself; it may not test the RV wiring
beyond the switch. In this case the hi-pot transfer switch
should be performed from either the transfer switch output,
or from the main panel, as well as from the plug to test the
cord itself.

The DLS series power converter/battery charger utilized
by the ILC converts 120 volts nominal A.C. to 13.6 volts
D.C. As a power supply, its tightly controlled regulation
allows the user to operate any 12 volt nominal D.C. load
up to the converter’s rated output current. As a battery
charger, the converter will maintain the battery, deliver-
ing its full-rated current when the battery capacity falls
sufficiently low. The voltage is set to deliver its maxi-
mum current for the necessary period of time that mini-
mizes undue stress to the battery caused by heating of
its cells. This helps to ensure the longest possible life
of the battery. Over time, as the battery nears its full
capacity, the converter will float-charge the battery to
prevent self-discharge of its cells.

The DLS series power converter/battery charger is designed
with high quality components to help ensure years of con-
tinuous use. The DLS series is protected by multiple pro-
tection features for a long, trouble-free life.
1) Reverse Battery Polarity Protection. 2) Brown-Out
Input Protection. 3) Over-Current Protection - cycle
by cycle peak limiting as well as rated current limiting
to maximize the life of the converter. 4) Over-Tem-
perature Protection. In addition, it is designed with a
unique “proportional” fan control circuit. Fan speed is
directly proportional to the converter’s internal ambi-
ent temperature. This enables the fan to turn on and
off very slowly, minimizing unwanted fan-starting noise.
