Installation
9
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.

Installing and wiring in compliance with EMC Directive
Effective 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
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 filter
•
Connect a noise filter 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 filter to the AC input side of the power supply
transformer.
•
For a noise filter, use HF2010A-UPF (SOSHIN ELECTRIC CO., LTD), FN2070-10-06 (Schaffner EMC) or equivalent
product.
•
Install the noise filter 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 mm
2
or more) and output cables (AWG18: 0.75 mm
2
or more)
firmly to the surface of the enclosure.
•
Connect the ground terminal of the noise filter to the grounding point, using as thick and short a wire as possible.
•
Do not place the AC input cable parallel with the noise filter output cable. Parallel placement will reduce noise filter
effectiveness 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 filter must be as thick and short as possible so that no
potential difference 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 mm
2
) 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 figure.
