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.

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
3m
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.

5.3 Ground connection
• Connect a ground wire to the FG terminal (pin 5) on the power supply
connector (CN4).
FG terminal
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
DIN rail
to a D-class ground specification (resistance of 100 Ω maximum).
• The cross-sectional area of the ground cable shall be 2 mm
• The Grounding point should be as near as possible to the gateway.
Keep the grounding cable as short as possible.
