Install it in a well-ventilated location that provides easy access for inspection. The location must also satisfy the
following conditions:
•Inside an enclosure that is installed indoors (provide vent holes)
•Operating ambient temperature 0 to +40 °C (+32 to +104 °F) (non-freezing)
•Operating ambient humidity 85% or less (non-condensing)
•Area that is free of explosive atmosphere or toxic gas (such as sulfuric gas) or liquid
•Area not exposed to direct sun
•Area free of excessive amount of dust, iron particles or the like
•Area not subject to splashing water (rain, water droplets), oil (oil droplets) or other liquids
•Area free of excessive salt
•Area not subject to continuous vibration or excessive shocks
•Area free of excessive electromagnetic noise (from welders, power machinery, etc.)
•Area free of radioactive materials, magnetic elds or vacuum
4-2 Installation method
Install the NETC01-M2 to a 35 mm (1.38 in.) width DIN rail.
There must be a clearance of at least 50 mm (1.97 in.) in the horizontal
and vertical directions, between the NETC01-M2 and enclosure or
other equipment within the enclosure.
When installing two or more NETC01-M2 in parallel, it is possible to
install them closely in the horizontal direction. Provide a minimum
clearance of 50 mm (1.97 in.) in the vertical direction.

Removing from DIN rail
Pull the DIN lever down until it locks using a slotted screwdriver, and lift the bottom of
the NETC01-M2 to remove it from the rail.
Use force of about 10 to 20 N (2.2 to 4.5 lb.) to pull the DIN lever to lock it. Excessive
force may damage the DIN lever.
4-3 Installing and wiring in compliance with EMC Directive
Eective measures must be taken against the EMI that the NETC01-M2 may give to adjacent control-system
equipment, as well as the EMS of the NETC01-M2 itself, in order to prevent a serious functional impediment in the
machinery. The use of the following installation and wiring methods will enable the NETC01-M2 to be compliant
with the EMC Directive. Refer to “CE Marking” on p.5 for the applicable standards.
Oriental Motor conducts EMC measurements on its NETC01-M2 in accordance with“Example of NETC01-M2
installation and wiring”on p.10. The user is responsible for ensuring the machine’s compliance with the EMC
Directive, based on the installation and wiring explained below.
Power supply
This network converter is a product of DC power supply input.
Use a DC power supply (switching power supply etc.) that conforms to the EMC Directive.
Noise lter
•Connect a noise lter in the DC power supply input to prevent the noise generated in the NETC01-M2 from
propagating externally through the power supply line.
•When using a power supply transformer, be sure to connect a noise lter to the AC input side of the power supply
transformer.
•For a noise lter, use HF2010A-UPF (SOSHIN ELECTRIC CO., LTD), FN2070-10-06 (Schaner EMC) or equivalent
product.
•Install the noise lter as close to the AC input terminal of DC power supply as possible. Use cable clamps and other
means to secure the AC input cables (AWG18: 0.75 mm2or more) and output cables (AWG18: 0.75 mm2or more)
rmly to the surface of the enclosure.
•Connect the ground terminal of the noise lter to the grounding point, using as thick and short a wire as possible.
•Do not place the AC input cable parallel with the noise lter output cable. Parallel placement will reduce noise lter
eectiveness if the enclosure’s internal noise is directly coupled to the power supply cable by means of stray
capacitance.
How to ground
The cable used to ground the NETC01-M2 and mains lter must be as thick and short as possible so that no
potential dierence is generated. Choose a large, thick and uniformly conductive surface for the grounding point.
Wiring the power supply cable and I/O signal cable
•Use a shielded cable of AWG22 (0.3 mm2) or more for the power supply cable of the NETC01-M2, and keep it as
short as possible.
•For the MECHATROLINK-II communication cable, use a dedicated cable with connector.
•To ground the power supply cable , use a metal cable clamp or
similar device that will maintain contact with the entire
circumference of the cable. Attach a cable clamp as close to the end
of the cable as possible, and connect it as shown in the gure.

Notes about installation and wiring
•Connect the NETC01-M2 and other peripheral control equipment directly to the grounding point so as to
prevent a potential dierence from developing between grounds.
•When relays or electromagnetic switches are used together with the system, use noise lters and CR circuits to
suppress surges generated by them.
•Keep cables as short as possible without coiling and bundling extra lengths.
•Place the power cables such as the motor and power supply cables as far as 100 mm (3.94 in.) from the signal
cables. If the power cables and signal cables have to cross, cross them at a right angle. Place the AC input cable and
output cable of a noise lter separately from each other.
