Overview

The Moxa INJ-24A Series high-power PoE+injector is a 1-port PoE+
injector that delivers both data and electrical power to Ethernet-enabled
devices using a single Ethernet cable. The INJ-24A can supply up to 36
watts of power in 2-pair mode or 60 watts in 4-pair mode through the
Ethernet port, and can power IEEE 802.3af/at compliant powered devices
(PD), such as wireless access points or IP cameras, eliminating the need
for additional wiring. The INJ-24A supports Gigabit communication, which
is vital for high-speed and low-latency applications. The INJ-24A also
offers a wide operating temperature range of -40 to 75°C, and is designed
to withstand a high degree of vibration and shock. An innovative
hardware design enhances the INJ-24A with flexible options of Mode A
and Mode B PoE powering modes. This makes the INJ-24A perfect for
outdoor field installation of M12-connector wireless APs and IP cameras
which only have 4 pins in the cable. In addition, the INJ-24A can resist
3KV surges from the PoE port, protecting system operations in critical
industrial environments, and complies with CE/FCC and UL standards for
safety.

Wiring Requirements

WARNING

Do not disconnect modules or wires unless the power supply has
been switched off o

r the area is known to be non-

hazardous. The
devices may only be connected to the supply voltage shown on
the type plate. The devices are designed for operation with a
Safety Extra-Low Voltage. Thus, they may only be connected to
the supply voltage connections and to the signal contact with the
Safety Extra

-Low Voltages (SELV) in compliance with IEC

60950-1/EN 60950-1.

WARNING

The power for this product is intended to be supplied by a Listed
Power Unit, with output marked LPS, and rated to deliver 24 DC
at a maximum of 3.72 A.

WARNING

This unit is a built

-in type. When the unit is installed in another

piece of equipment, the equipment enclosing the unit must
comply with fire enclosure regulation IEC 60950

-1/EN60950-1

(or similar regulation).

WARNING

Safety First!

Be sure to disconnect the power cord before

installing and/or

wiring your Moxa PoE injector. Calculate the maximum possible
current in each power wire and common wire. Observe all
electrical codes dictating the maximum current allowable for each
wire size. If the current goes above the maximum ratin

gs, the

wiring could overheat, causing serious damage to your
equipment.

You should also pay attention to the following items:

• Use separate paths to route wiring for power and devices. If power
wiring and device wiring paths must cross, make sure the wires are
perpendicular at the intersection point.

• NOTE: Do not run signal or communications wiring and power wiring
in the same wire conduit. To avoid interference, wires with different
signal characteristics should be routed separately.

• 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 wiring that shares similar electrical characteristics can be
bundled together.

• Keep input wiring and output wiring separated.

• It is strongly advised that you label wiring to all devices in the system

when necessary.
