Product Overview

DIN-Rail Mounting and Dismounting Instructions

Mounting the Switch Removing the Switch

Click

Push Push

Click

ATTENTION: The NFI-U08-2A 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airow.

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speciedontheproductlabel.Calculatethe

maximum possible current in each power wire and

commonwire.Conrm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gure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speciedvoltageand

maximum electric current to the power terminal block, follow these

steps:

•Useaat-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.

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-conguredevents.Thetwowiresattachedtothe

faultcontactsformanopencircuitwhenauser-conguredevent

istriggered.Ifauser-conguredeventdoesnotoccur,thefault

circuit remains closed.
