2-2 Method for adapting to CE marking
2-2-1 Metal Enclosure
MICREX-SX Series products are classified as "enclosed type" equipment. "Enclosed type" means equip-
ment that is designed on the condition that it is installed in an enclosure such as a metal enclosure, so that
electric shock or other accidents do not occur due to the human body coming into contact with the product
(MICREX-SX). In other words, there may be danger of an electric shock, etc., if the product is not accom-
modated in an enclosure. (For example, a steel wire may be inserted in one of the cooling slots provided
on the product body.)
MICREX-SX Series products also need to be installed in a metal enclosure in order to control the electro-
magnetic radiation noise (EMI) they emit. Basic specifications for the metal enclosure are as follows.
Material : SPCC (high-tensile-strength steel)
Plate thickness: Min. 1.6 mm
Power supply : Power supplied to the control panel should be protected from external surge voltage with
an insulating transformer.
Remarks : Should be structured so that an electromagnetic radiation noise does not leak from the
enclosure.
For example, in the figure below, a box-type door is used, and the enclosure has an eave-
like protrusion that overlaps on the side faces of the door when closed.
The important point here is that the overlap of the door and the enclosure's main body
effectively prevents electromagnetic radiation noise from leaking out of the enclosure.

2-2-2 How to lay the SX bus cable
<Mounting the ferrite core>
A high-speed electric signal flows through the SX bus cable. Therefore, high-frequency noise is emitted
from the SX bus cable, making it impossible for the product to conform to the EMC directive concerning CE
marking.
To solve this problem, a ferrite core is mounted at the base of the SX bus cable.
Mount the ferrite core according to the figure below.
<How to affix the cable to the metal enclosure>
When affixing the SX bus cable to the metal enclosure, be sure to secure a 1-cm or wider gap so that the
SX bus cable does not come into contact with the metal plate.
On the one hand, the metal enclosure provides an effective shield fromelectromagnetic radiation noise; on
the other hand, it becomes an effective antenna that electromagnetic radiation noise if a cable as a noise
source is nearby or comes into actual contact with it. Not only the SX bus cable, but also other high-speed
signal transmission cables need to be kept away from the metal walls of the enclosure.

2-2-3 Adaptation of individual module
(1) T-link master/interface module (NP1L-TL1 / RT1)
When a T-link master module is used, it is necessary to mount the ferrite core at the base of the communi-
cation cable as well as affix insulating sheet. When the T-link interface module is used, it is necessary to
mount the ferrite core at the base of the communication cable.
1) Mount the ferrite core at the root of the communication cable.
2) Affix the static electricity preventive insulating sheet to the station number-setting switch
When a station number needs to be changed while the module is operating, it is once necessary to remove
the insulating sheet for this work. For this operation, the operator must remove static electricity accumu-
lated on his body by means of a static elimination band or the like before touching the station number-set-
ting switch. This is necessary only for the T-link master module (NP1L-TL1), and not necessary for the T-
link interface module (NP1L-RT1).
* Ferrite core mounting may be unnecessary if all of
the communication cable is laid only inside the
metal enclosure, or even when it is laid outside the
metal enclosure, if it is laid in EMI shielding tube or
metal tube so that no noise leaks out.

Note:
If vibration or shock is applied to the product, a
strong force due to the weight of the ferrite core
may act on the cable to damage it. Be sure to af-
fix the cable to a firm object such as a duct so
that the cable does not swing under vibration.
Affix the insulating sheet supplied with the product on the station number-
setting switch.
Note: For the purpose of explanation, a colored sheet is used in the
photo at left. The actual insulating sheet supplied with the prod-
uct is transparent.

(2)OPCN-1 master module (NP1L-JP1)
When a OPCN-1 master module is used, it is necessary to the stick-insulating sheet.
1) Affix the static electricity preventive insulating sheet to the station number-setting switch
When a station number needs to be changed while the module is operating, it is once nec-
essary to remove the insulating sheet for this work. For this operation, the operator must
remove static electricity accumulated on his body by means of a static elimination band or
the like before touching the station number-setting switch.
(3) FL-net ( OPCN-2 ) module (NP1L-FL1)
When the "FL-net ( OPCN-2 )" module is used, in order to control electromagnetic radiation noise emitted
from the communication cable, a ferrite core needs to be mounted at the base of the cable.
1) Mount the ferrite core at the base of the communication cable.
Affix the insulating sheet supplied with the product on the station number-
setting switch.
Note: For the purpose of explanation, a colored sheet is used in the photo
at left. The actual insulating sheet supplied with the product is
transparent.

(4) Precautions for using the "AS-i" master module (NP1L-AS1)
When the "AS-i" module is used, the operator who works on the terminal block for connecting the signal
cable must discharge static electricity accumulated on his body by means of a static elimination band or
the like before touching the terminal block so that static discharge to the terminal block does not occur.

Section2 Conformance with CE marking
(6) Measures for the positioning modules
When one of the following modules is used, a ferrite core needs to be mounted at the base of all the cables
connected to the module as well as the power and FG cables leading to the power module mounted on the
baseboard on which the positioning module is also mounted.

3-1 Adaptation to UL standard
No restriction
3-2 Adaptation to Lloyd's Register of Shipping / NK
Ship standards such as Lloyd's Register of Shipping and NK (Nippon Kaiji Kyokai) are almost the same as that for CE
marking, except that vibration- related rules are more severe in the former than in the latter.
Therefore, when a MICREX-SX Series product is used for marine equipment, tightly wind a strong nylon band around the
entire PLC so that the modules come in close contact with each other, as shown in the figure below.
A guideline for checking the propriety of the contact is whether or not a name card can be inserted in between the mod-
ules.
Fix by tightly winding a nylon band
around the SX.
After fixing with a nylon band, check to see that a
name card cannot be inserted in the gap be-
tween the modules.

4-1 Installing PC uints
1) Keep an open space of 110mm (vertical) or 10mm (horizontal) between the PC unites, between remote I/O modules the
PC unit and remote I/O module.
Note:When the base board is mounted on a DIN rail, keep an open space of 80mm in consideration of mounting bracket
dimensions and the workability.
2) Keep an open space of 50mm between the PC unit and other device and between the PC unit and the wall to obtain
sufficient ventilation.
3) Avoid installing heat generating devices (heaters, transformers, or resistors) underneath the PC unit.
4) Shield or separate the PC unit as far from high voltage device, high-voltage cables, or power equipment as possible.
Avoid installing PC I/O cables unit and high-voltage or power equipment cables in parallel.
5) Install the PC unit perpendicular to the panel floor.
6) The PC must be installed in a vertical position. Do not install the PC in other position.

1) Wiring of power supply
For AC power supply
Wire to a 100 to 120V AC or 200 to 240V AC power supply.
The thickness of the wire must be 2mm2, and the wire must ne twisted densely.
For DC power supply
Wire to a 24V DC power supply (22.8-26.4V DC).
The thickness of the wire must be 2mm2, and the wire must ne twisted densely.
[Tips]
The tolerance range of MICREX-SX AC power supply is 85 to 132V AC for 100V AC, and 170 to 264V AC for 200V AC. But
the voltage is recommended to be as near the rated voltage (100 to 110V AC, 200 to 220V AC) as possible.
In the case of the lower voltage, a small voltage drop will cause a power failure. In the case of the higher voltage, the heat-
ing value of the power supply module increases and it reduces the life of the module. If power supply voltage fluctuation
exceeds the specified range, connect a voltage stabilizer to the power supply.
For noise reduction of the power supply, an insulating transformer or a noise filter is effective between the breaker and the
power supply module. Take care of the following points:
• Do not bundle up or do not close the insulating transformer or the noise filter.
• Keep the distance between the insulating transformer (or the noise filter) and the power supply module as short as
possible, and the cable must be twisted densely.

3) Grounding
• Connect the FG terminal to the integrated ground section of each control panel (FG bus, FG integrated terminal block, or
stud) in branch-type configuration. The thickness of the ground wire must be 2mm2. Allocate the grounding point as near
the module as possible, and keep the ground wire as short as possible.
• The integrated ground section of each control panel must be connected to the integrated ground board, which is installed
according to the distribution of devices in a branch-type configuration. The thickness of the ground wire must be 5.5mm2
or more.
• Separate the ground wire as far from the lines of high-voltage circuits and main circuit as possible. In addition, keep the
distance at which they run in parallel as short as possible.
• For grounding, use an exclusive ground pole and wire which are separated from the ground system of other power cir
cuits.
• The grounding should be exclusive. The grounding resistance is 100 or less. Separate the ground pole 10m or more
from that of other power circuit.
• When installing in a place affected by frequent lighting surges, all the CPU modules and input/output modules should be
electrically insulated from the control panel. Also, modules and units should be earthed to ground individually.
Do not open the FG terminal with LG-FG short circuited. (It must be grounded, otherwise it might cause electric
shock.)
