2. Insert expansion plugs into the holes and then insert bolts, ensuring 3-5mm protrudes from the expansion plug.
3. Unscrew the fixing bolts from the adapter's base, remove the bottom cover, and proceed with wiring as per the diagram.

3.5 Electrical wiring

1) Remove the case:

a. Remove rubber plugs and screws.

b. Detach the case by pulling in the direction of the arrow.

2) Connect electric wires according to the diagram:

The diagram shows the adapter (HCCS-H64H2C1M) with connections to the Address DIP switch, Electric meter, Outdoor unit, Indoor unit, Router, and Power adapter. The wiring includes 485 commu. cable, H-NET commu. cable, and Internet cable.

• H-NET communication cable connects to H-NET terminals 1 and 2 of indoor and outdoor units.
• 485 communication cable connects to the RS485 end of the electric meter (A to D1+, B to D0-).
• Internet cable connects to the router's LAN port for wired connections.
• Power adapter connects to the AC100-240V plug, selecting the appropriate AC plug for on-site conditions.

• b. Fix wires at the designated trunking location.

4. Configuration

4.1 DIP switch setting

When multiple adapters (up to 3) are connected to one H-NET communication cable, DSW1 must be set. The diagram indicates DIP switch positions (ON/OFF) for addresses 0xA0 through 0xA7.

Note: ☑ indicates the location of the DIP switch; ☐ indicates no attention is needed.
