Repeater Installation

Push the cover hard on the screwdriver icon till the snap fasteners of the cover separate from the base, then open the cover. Install the power cables and communications wires properly according to the wiring diagram. Warning
- Make sure the power is off when operating.
- Do not raise the upper cover with excessive force to avoid damage to the cover or the circuit board.
Fix the repeater base on the wall or a proper location with a screwdriver. Four positions need to be fixed with screws.
Finally, close the upper cover and the bottom cap of the repeater and tighten them with two fixing screws.

Warning
Make sure that no cables are clamped when buckling the upper cover and bottom cap of the repeater.

Power Cable Connection

Warning

The power supply of the repeater cannot be cut off separately. It needs to be always powered on or switched on and off with the ODU power supply.
Use round-type terminals with correct specifications to connect the power cable. The power cables must be a 2×1.0mm copper core cable.2
Connect the power cable with terminals L and N.

Connection of the power cable

First wiring method:
Let the power cable through the hole on the left side of the repeater to the CN1 power supply terminal (L N). Fix the wires with clamps to avoid stress on the terminal block.

Connection of the power cables

Second wiring method:
Let the power cable through the hole on the bottom side of the repeater to the CN1 power supply terminal (L N). Fix the wires with tie to avoid stress on the terminal block.

Communication Wire Connection

Warning

Do not connect M1M2 with the IDU’s PQ, D1D2 or X1X2 or any other different communication network. Otherwise, the circuit board will be damaged.
If the total communication distance between IDU and ODU exceeds 200m or more than 10 IDUs are configured, use a repeater to increase the bus voltage.
A maximum of 2 repeaters can be installed in the same refrigerant system.
Use 2×1.5mm PVC sheathed flexible cords in compliance with AS NZS 3000 Electrical installations (known as the Australian New Zealand Wiring Rules) and AS NZS 3008 Electrical Installations (DC resistance ≤ 1.33Ω/100m) as communication cables.
Note the distinction between the communication port of the upstream IDU and that of the downstream IDU. Be careful not to make them confused. Otherwise, communication failure will occur.
Connect the port of TO UP IDU with the upstream IDU. The upstream IDU is located in front of the repeater and near the ODU.
Connect the port of TO DOWN IDU with the downstream IDU. The downstream IDU is located behind the repeater and away from the ODU.

Connection of communication wires

First wiring method:
The communication wire should pass through the wire clamp on the right side of the repeater. The communication wire of the upstream IDU should be connected with the CN3 (TO UP IDU) terminal block(M1 M2) while the communication wire of the downstream IDU connected with the CN2 (TO DOWN IDU) terminal block(M1 M2). The wires should be fixed with clamps to avoid stress on the terminal block.

Warning

Do not connect the communication wire when the power is on, or the circuit board will be damaged.
Note the distinction between the upstream IDU and the downstream IDU. Be careful not to make them confused. Otherwise, communication failure will occur.
Please follow the path shown in the figure. The path cannot touch the components on the motherboard.

Connection of communication wires

Second wiring method:
The communication wire should pass through the wire clamp on the bottom side of the repeater. The communication wire of the upstream IDU should be connected with the CN3 (TO UP IDU) terminal block(M1 M2) while the communication wire of the downstream IDU connected with the CN2 (TO DOWN IDU) terminal block (M1 M2). The wires should be fixed with a tie to avoid stress on the terminal block.

Connection mode

L1+La+Lx≤200m, L11+Lb+Ly≤200m, L21+Lc+L30≤200mm, communication wire: 2×1.5mm2.
The above figure shows a connection in series. Please refer to the installation manual of the outdoor unit and the respective controller and or please contact ActronAir Technical support for assistance.

Warning

If the total communication distance does not exceed 200m and no more than 10 IDUs are configured, the units are powered by the master ODU, and no repeaters are required. If the total communication distance exceeds 200m or more than 10 IDUs are configured, repeaters are required.
The repeaters shall have the same load capacity as the ODUs, connecting with up to 10 IDUs, with a communication distance of no greater than 200m.
A maximum of two repeaters can be installed in the same refrigerant system.
A maximum of 30 IDUs can be installed in the same refrigerant system by using repeaters.
