Safety Information
Follow these instructions carefully. Improper work may seriously harm your
health and damage the gateway and/or any other equipment connected to it.
Only technical personnel, following these instructions and the country legislation for installing
electric equipment, can install and manipulate this gateway.
Install this gateway indoors, in a restricted access location, avoiding exposure to direct solar
radiation, water, high relative humidity, or dust.
All wires for communication and power supply (if needed) must only be connected to networks
without routing to the outside plant. All communication ports are considered for indoor use and
must only be connected to SELV circuits.
Disconnect power wires before manipulating and connecting them to the gateway.
Respect the expected polarity of power (if needed) and communication cables when connecting
them to the gateway.
Mounting
Mount the gateway inside the AC indoor unit, over a wall, or over a DIN rail.
Do not mount the gateway in air-handling units or conducts.
DIN rail mounting inside a grounded metallic cabinet is recommended.
Mounting the gateway inside the AC indoor unit
1. Look for the proper place to mount the gateway, taking into consideration the following:
• Keep communication cables away from power and ground wires.
• Ensure the gateway does not block any mobile parts of the AC unit.
2. Leave the gateway on top of a secure, plain surface.
3. Use double-sided tape to ensure a secure fixing if needed.
Wall mounting
1. Press the rear panel clips outwards until you hear a click.
2. Use the clip holes to screw the gateway to the wall.
3. Make sure the gateway is firmly fixed.
DIN rail mounting
Keep the clips in its original position.
1. Fit the gateway's top-side clip in the upper edge of the DIN rail.
2. Press the low side of the gateway gently to lock it in the DIN rail.
3. Make sure the gateway is firmly fixed.
For some DIN rails, to complete step 2, you may need a small screwdriver or
similar to pull the bottom clip down.

Figure 1. Wiring diagram (wire colors are indicative only)
This cable is 1.5 m (4.9 feet) long. Its modification in length may affect the
correct operation of the gateway.
AC unit connection: Plug the largest unsheathed cable part connector into the socket
CN105 (CN92 in some units) of the AC unit control board.
Gateway connection: Plug the other end connector, the one on the shortest
unsheathed part of the cable, into the socket labeled as AC Unit.
Observe polarity: B -, A +, and SG for ground connection.
Keep communication cables away from power and ground wires.
