ATTENTION: The NGI-U08A is an open-type device
and shall be DIN-rail mounted or wall mounted
(optional) in a cabinet or rack enclosure. The
ambient temperature should not exceed 75°C
(167°F).
Mounting the Switch
Place the switch on the DIN rail from above using the built-in
slot. Push the front of the switch toward the mounting surface
until it snaps into place. You will hear a “click” to indicate it has
successfully snapped into place.
Dismounting the Switch
Press the switch from the top, then pull out the lower edge of the
switch to remove it from the DIN rail.

DIN-Rail Mounting and Dismounting Instructions
ATTENTION: A corrosion-free DIN mounting rail is
advisable. When mounting the switch, be sure to
allow enough space between devices to install the
cabling and to ensure proper airflow.
Grounding the Switch
Grounding and wire routing help limit the effects of line noise
caused by electromagnetic interference (EMI). Run the ground
connection from the ground screw to the grounding surface, then
connect the ground connection from the terminal block to the
grounding surface prior to connecting devices.
ATTENTION: This switch is intended for mounting on a well-
grounded surface, such as a metal panel.

WARNING: Safety measures should be taken before
connecting the power cable. Turn off the power before
connecting modules or wires. The correct power supply
voltage is listed on the product label. Check the voltage
of your power source to make sure you are using the
correct voltage. DO NOT use a voltage greater than
what is specified on the product label. Calculate the
maximum possible current in each power wire and
common wire. Confirm all electrical codes dictating
the maximum current allowable for each wire size. If
current exceeds the maximum rating, the wiring can
overheat causing serious damage to your equipment.
Please read and follow these guidelines:
• 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
through 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. Wiring
that shares similar electrical characteristics can be bundled
together.
• You should separate input wiring from output wiring.
• Be advised that you should label the wiring to all devices in the
system.

Wiring Requirements
Wiring Power Input
You can use “PWR” for Primary Power input and “RPS” for
Redundant Power Input. Check the polarity while connecting. The
top view of the Terminal Block is shown in the figure below:
CAUTION:
• Use copper conductors only.
• Wiring cable temperature should support at least 105°C
(221˚F).
• Tighten the wire to a torque value 0.5 N•m (4.5 in•lb).
Note: The wire gauge for the terminal block should range between 12
and 24 AWG.

Wiring Requirements
To insert power wire and connect the specified voltage and
maximum electric current to the power terminal block, follow
these steps:
• Use a flat-head screwdriver to loosen the wire-clamp screws.
• Insert the negative/positive DC wires into the PWR-/PWR+
terminals, respectively.
• Tighten the wire-clamp screws to prevent the wires from
loosening.
ATTENTION: Use a power supply from 12~48VDC, 0.5A
maximum. The device power shall be supplied by LPS circuit.

10
Wiring Requirements
Wiring the Relay Contact (ALM)
The switch has one set of relay alarm output. This relay contact
uses two contacts of the terminal block on the switch top panel.
The two contacts of the 6-pin terminal block connector are used
to detect user-configured events. The two wires attached to the
fault contacts form an open circuit when a user-configured event
is triggered. If a user-configured event does not occur, the fault
circuit remains closed.

Cabling
Connect one end of an RJ45 Ethernet cable (see Optional
Accessories) into the switch’s RJ45 Ethernet port. Connect
the other end to a network device. Cat5e cable or above is
recommended.
• Ports 1-8 of the switch support Gigabit Ethernet (10/100/1000
Mbp speeds)
• All ports support auto-negotiation and auto MDI/MDI-X to
eliminate the need for crossover cabling.
