4 Installation
4.1 Installation
Warning
•Do not install the product unless the safety instructions have been read
and understood.
4.2 Mounting
•The gateway can be direct mounted (model LEC-GMJ2) using 2 x M4
screws or mounted on a DIN rail (model LEC-GMJ2D).
•When using DIN rail mounting, hook the gateway on the DIN rail and
press the lever in the direction of Arrow A to lock it.
Direct mounting DIN rail mounting
4.3 Environment
Warning
•Do not use in an environment where corrosive gases, chemicals, salt
water or steam are present.
•Do not use in an explosive atmosphere.
•Do not expose to direct sunlight. Use a suitable protective cover.
•Do not install in a location subject to vibration or impact in excess of
the product’s specifications.
•Do not mount in a location exposed to radiant heat that would result in
temperatures in excess of the product’s specifications.
•Avoid mounting the gateway near a vibration source, such as a large
electromagnetic contactor or circuit breaker on the same panel.
•Do not use in an environment with strong magnetic fields present.
5 Wiring
5.1 Wiring
Caution
•Do not perform wiring while the power is on.
•Confirm proper insulation of wiring.
•Do not route wires and cables together with power or high voltage
cables.
•Keep wiring as short as possible to prevent interference from
electromagnetic noise and surge voltage.
•Do not use an inrush current limited type of power supply for the
gateway.
•Do not connect multiple wires to one connector terminal.
5.2 Power Supply Connector (CN4)
Wire the power supply cable to the power supply plug connector, then
insert it into connector CN4 on the gateway.
•Use special screwdriver (Phoenix Contact
No. SZS0.4×2.0) to open / close the lever
and insert the wire into the connector
terminal.
•Applicable wire size:
20 AWG (0.5 mm
2
).

5.3 Ground connection
•Connect a ground wire to the FG terminal (pin 5) on the power supply
connector (CN4).
Caution
The M4 screw, cable with crimped terminal and shakeproof washer must
be prepared by the user.
The gateway must be connected to Ground to shield it from electrical
noise.
•A dedicated Ground connection must be used. Grounding should be
to a D-class ground specification (resistance of 100 Ωmaximum).
•The cross-sectional area of the ground cable shall be 2 mm
2
minimum.
•The Grounding point should be as near as possible to the gateway.
Keep the grounding cable as short as possible.

9 Maintenance
9.1 General Maintenance
Caution
•Not following proper maintenance procedures could cause the product
to malfunction and lead to equipment damage.
•Before performing maintenance, turn off the power supply. Check the
voltage with a tester 5 minutes after the power supply is turned OFF.
•If any electrical connections are disturbed during maintenance, ensure
they are reconnected correctly and safety checks are carried out as
required to ensure continued compliance with applicable national
regulations.
•Do not make any modification to the product.
•Do not disassemble the product, unless required by installation or
maintenance instructions.
Caution
•Maintenance should be performed according to the procedure
indicated in the Operation Manual.
•When equipment is serviced, first confirm that measures are in place
to prevent dropping of work pieces and run-away of equipment, etc,
then cut the power supply to the system. When machinery is restarted,
check that operation is normal with actuators in the correct position.
Warning
•Perform maintenance checks periodically.
•Conduct an appropriate functional inspection and test after completing
maintenance. In case of any abnormalities (if the actuator does not
move, etc.), stop the operation of the system. Otherwise, an
unexpected malfunction may occur and it will become impossible to
ensure safety. Operate an emergency stop instruction to confirm
safety.
•Do not put anything conductive or flammable inside of the gateway.
•Ensure sufficient space around the gateway for maintenance.
