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.
Mount the gateway, preferably, on a DIN rail inside a grounded metal cabinet following the
instructions below.
In the case of wall mounting, firmly fix the gateway on a non-vibrating surface following the
instructions below.
Disconnect power wires before manipulating and connecting them to the gateway.
Use SELV-rated NEC class 2 or limited power source (LPS) power supply.
Use a circuit-breaker before the power supply. Rating 250 V, 6 A.
Supply the correct voltage to power the gateway. See the Technical Specifications table at the end
of this document.
Respect the expected polarity of power (if needed) and communication cables when connecting
them to the gateway.
This gateway is designed for installation inside an enclosure. When working inside an enclosure
(ex. to make adjustments, set switches, etc.), observe the common antistatic precautions before
manipulating the gateway.

For further information on the installation, connection, and configuration of this gateway, refer to
the User manual.
Mounting
Mount the gateway 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.
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.
Wiring
https://
1. Connect the P1P2 bus to the gateway's RC bus connector. This bus has no specific polarity.
2. Connect the BACnet MS/TP or Modbus RTU bus to the EIA-485 port of the gateway.
3. Reconnect all systems to power.

Figure 1. Wiring diagram (wire colors are indicative only)
Disconnect all systems from power before wiring the gateway.
The maximum length for the RC bus cable is 500 m (1640 ft). To know more,
consult the AC indoor unit technical documentation.
Observe polarity: B -, A +, and SG for ground connection.
Keep communication cables away from power and ground wires.
Connection to an external power supply: This gateway is powered by the AB bus
itself, and there is no need to connect an external power supply. Nonetheless, the
bus could not supply the needed power* depending on the number and type of
remote controllers installed. If that's the case, connect a 12 VDC/VAC SELV-rated
NEC class 2 or Limited Power Source (LPS) power supply in the gateway's Power
connector.
*Some signs indicating there is not enough power in the bus may include, for
example, a malfunction of the remote controllers' displays or performance.
