▷ You can use the type of signal transmitted
through a wire to determine which wires should
be kept separate. The rule of thumb is that wir-
ing with similar electrical characteristics can be
bundled together.
▷ Keep input wiring and output wiring separate.
▷ It is strongly advised that you label wiring to all
devices in the system when necessary.
ATTENTION
– This product is intended to be supplied by a Listed
Power Unit marked "Class 2" or "LPS" and rated
O/P: 9.6 W (12 V/0.78 A to 48 V/0.2 A).
– Make sure that the external power adapter (in-
cludes power cords and plug assemblies) pro-
vided with the unit is certified and suitable for use
in your country.
– Use the antennas correctly!
Wide-band (2G/3G/4G) antennas are needed
when the OnCell G3150A-LTE operates. Make
sure that your antenna installation is within a safety
area, which is covered by a lightning protection
or surge arrest system.
WARNING
Do not locate the antenna near overhead power
lines or other electric light or power circuits, or
where it can come into contact with such circuits.
When installing the antenna, take extreme care not
to come into contact with such circuits, because
they may cause serious injury or death when there
is a surge. For instructions on proper installation
and grounding of the antenna, refer to national and
local codes (for example, U.S.: NFPA 70, National
Electrical Code, Article 810, and Canada: Canadian
Electrical Code, Section 54).
Grounding the Moxa OnCell G50A-LTE
▷ Grounding and wire routing help limit the ef-
fects of noise due to electromagnetic interfer-
ence (EMI). Run the ground connection from the
ground screw to the grounding surface prior to
connecting devices.
▷ The minimum cross-sectional area of the ground-
ing conductor should be equal to that of the
input cable.
ATTENTION
This product is intended to be mounted on a well-
grounded mounting surface, such as a metal panel.
The potential difference between the two ground
potentials must be zero. If the potential difference
is NOT zero, the product could be permanently
damaged.
Connecting the Power Input
▷ Input Terminal Block (J3) is suitable for 12-28
AWG (3.31-0.0804 mm2) wire size, torque value
4.5 lb-in (0.51 Nm).

Wiring the Redundant Power Inputs
ATTENTION
Before connecting the OnCell G3150A-LTE to the
DC power inputs, make sure that the DC power
source voltage is stable.
▷ The top two pairs of contacts of the 10-contact
terminal block connector located on the top
panel of the OnCell G3150A-LTE are used as
the two DC inputs.
Top
Insert the negative/positive DC wires into the V-/
V+ terminals.
To keep the DC wires from pulling loose, use a
small flat-blade screwdriver to tighten the wire-
clamp screws on the front of the terminal block
connector.
Insert the plastic terminal block connector prongs
into the terminal block receptor, which is located
on the top panel of the OnCell G3150A-LTE.
Wiring the Relay Contact
▷ The OnCell G3150A-LTE has one relay output,
which consists of the two contacts of the terminal
block on the OnCell G3150A-LTE's top panel.
▷ For detailed electrical requirement, see page
7 (Specifications).
