■ INSTRUCTION MANUAL

This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.

POINTS OF CAUTION

■ CONFORMITY WITH EC DIRECTIVES

• The equipment must be mounted inside a panel.

• The actual installation environments such as panel con

­figurations, connected devices, connected wires, may affect
the protection level of this unit when it is integrated in
a panel system. The user may have to review the CE re­quirements in regard to the whole system and employ ad­ditional protective measures to ensure the CE conformity.

■ POWER INPUT RATING & OPERATIONAL RANGE

• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
100 – 240V AC rating: 85 – 264V, 47 – 66 Hz, approx. 8 – 11VA

24V DC rating: 24V ±10%, approx. 5.5W

■ SAFETY PRECAUTION

• Before you remove the unit or mount it, turn off the power
supply and input signal for safety.

■ ENVIRONMENT

• Indoor use

• When heavy dust or metal particles are present in the air,
install the unit inside proper housing with sufficient ven­tilation.

• Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.

• Environmental temperature must be within -5 to +60°C
(23 to 140°F) with relative humidity within 30 to 95% RH
in order to ensure adequate life span and operation.

• Be sure that the ventilation slits are not covered with ca

-

bles, etc.

■ WIRING

• Wrong connection may damage the unit.

• Do not install cables (power supply, network and output)
close to noise sources (relay drive cable, high frequency
line, etc.).

• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.

• Mixing with other networks may cause malfunction.

COMPONENT IDENTIFICATION

• Status

Bicolor LED which changes from green to red according to
the unit’s status.

Green

LAN ports are in normal communication status.

Red

Communication is lost due to the control circuit failure.
Replace the unit.
Alarm contact output is turned on.

• Surge Protector

Tricolor LED which changes from green to orange to red
according to the unit’s status.

OFF

When the power supply is turned on for the first time af

­ter the unit has been installed, the LED is OFF indicating
that it is in the initial state.

Green

The unit has been subjected to a lightning surge for the

first time. The LED turns on only when the power is sup­plied.

Orange

The internal surge protector is close to its end of life. Im

­mediate replacing the unit is recommended.

Red

The internal surge protector has degraded and is in ab

­normal status or at its end of life.

Immediate replacing the unit is required.
Alarm contact output is turned on.

• Startup LED Operation

Both Status and Protector LED turns to orange color for
approximately 1 second when the power supply is turned
on while the internal microprocessor is initialized. Status
of the unit and its surge protector as explained above is ir­relevant.

INSTALLATION

Set the unit so that its DIN rail adaptor is at the bottom.
Position the upper hook at the rear side of the unit on the
DIN rail and push in the lower. When removing the unit,
push down the DIN rail adaptor utilizing a minus screw­driver and pull.

TERMINAL CONNECTION

CONNECTING POWER SUPPLY / GROUND

■ POWER SUPPLY (DC power)

Two sets of power input terminals are available on this unit
(negative common).
In order to use two independent power sources for redun­dancy, connect each to the terminals 1 – 3 and 2 – 3 respec­tively. In this state, the unit can maintain its operation if
one of the power sources fails.
For single power supply, use either of these terminal sets.

■ GROUNDING

A surge protector is equipped at the LAN port to protect
the unit from surges entering through the LAN cable. It
is designed to direct the surges to the ground when they
enter the port as illustrated in the figure to the above right.
The G terminal, therefore, MUST be grounded. Grounding
resistance of 100Ω is recommended.

If you want to ground the system at multiple points in order
to separate noise interferences for information equipment
and for electric equipment:

1) When there is no potential difference between the two
grounding points, remove the shortcircuit bar connecting
FG and G terminals of this unit and connect the FG to
the ground for the information equipment, and the G to
that for the electric equipment.

2) When there is a potential difference, separate grounding
is not permitted. The shortcircuit bar must remain con­nected, and only the G terminal must be connected to the
grounding for electric equipment.

EXTERNAL DIMENSIONS mm (inch)

LAN CABLE

• To Use STP (Shielded Twisted Pair) Cable

Use of STP cables will enhance the protection effect, but
you must be aware that the LAN cable will be automatically
grounded at both ends as its shield will be connected to the
ground through the FG terminal.
If interference by common mode noise is suspected, use UTP
(Unshielded Twisted Pair) cable.

SURGE PROTECTION

This unit’s surge protection is applicable only to the LAN
ports. If the power input and alarm contact output termi­nals are connected to wires drawn from outside of the con­trol panel, we recommend use of surge protectors for these
points, too.
Please contact M-System to select appropriate models.

MAINTENANCE

Confirm the unit’s status by referring to ‘Indicator Func­tions’ table in Page 2 and replace it to a new one if neces­sary.
