Installation Steps
NOTE:
The purpose of this manual is to enable the installer to install
SG200 in a manner that permits it to operate as designed. This manual
is not intended to educate the installer on the regulatory requirements of
any particular type of installation. The manufacturer, supplier, dealer and/
or their agents cannot know what the final installation will be and therefore
cannot know what the regulatory requirements of such installation may be.
1. Determine a mounting location and mount the SmartShunt. The surface
should be flat. Do not install the SmartShunt on a curved surface. Note
that the cable connection bolts are not insulated on the underside of the
SmartShunt and therefore cannot be mounted onto a conductive surface.
2. Remove all loads and charging sources from the battery before any other
steps are taken. This often is accomplished by turning off a battery switch.
If there are loads or chargers directly attached to the battery, they should
be disconnected as well.
3. Connect the negative cables to both sides of the studs, as shown below.
NOTE:
In a simple installation, the battery Negative (-) cable is removed
from the battery, and connected to the “CABLE” end of the shunt. Then
a new, short cable is installed from the “BATT” (-) stud to the battery.
4. Re-install the lock washers and nuts on the shunt, the battery cable lug
goes first, then the washer, and then the nut.
NOTE:
DO NOT PLACE ANYTHING between the battery lug and the face
of the shunt. Do not use nylock nuts in place of the lock-nut and washer.
5. Connect the 60” Power lead to the battery P terminal. DO NOT
EXTEND the wire from the fuse to the fuse holder, this must be kept short
for safety reasons.
6. Connect the voltage sense leads to the auxiliary batteries. AUX-1 is a
solid orange wire, and AUX-2 is orange/black. Each AUX lead needs
to be fused within 6” of the battery. Fuses MUST BE INSTALLED FOR
THESE WIRES, and are not included. The wires do not carry any
current, so the fuse should be sized for the wire gauge and length. If
you need to extend the wire, do so with at least 18ga wire.
7. If the auxiliary batteries being monitored do not share a common
ground with the main battery bank connected to the shunt, a negative
lead must be wired from the auxiliary battery’s NEGATIVE post to the
“CABLE” post on the shunt.
8. Determine the mounting location of the Display. The Display is
weather-tight from the front, but not the rear. Do not install the display
where the rear of the unit is exposed to water. The cutout hole is
2.0625in in diameter. The maximum depth of surface that is supported
is 1/2 inch. Once the hole is cut, remove the nut, washer and mounting
brace, insert the display from the front and then replace the brace.
Tighten the nut by hand, and then 1/2 turn or so. If it is being mounted
in a plastic dash, do not over-tighten the nut or you could risk cracking
the dash.
9. Run the SmartLink Cable from the SmartShunt to the Display. Since
one end has the Deutsch connector pre-terminated, and the other
does not, it may be better to start from one end or the other, depending
on the installation. Make sure that there is chafe protection if the cable
passes through bulkheads. The cable should be supported every 18
inches.
10. Install the Deutsch-style connector onto the pins of the SmartLink
Cable. See the following section that illustrates this procedure.
NOTE:
DO NOT insert pins before reading these instructions entirely.
11. Connect the Smartlink Cable to both the Display and the SmartShunt.
You can connect to either connector on each device. Press the con-
nector into the receptacle until it snaps into place.
12. Insert the included fuse into the fuse holder. At this point the Display
will power up, and be operational in a few seconds.
NOTE: You may add a new device at any time. However,
you MUST remove and re-apply power to the entire
network for the new device to be recognized.
NOTE:
The fuse holder is
shipped without the fuse
installed. Install the fuse
AFTER completely connecting
all of the wires/cables and
all other installation steps.
