Remote Keyboard From 200 Metres Up To 500 Metres - Mitsubishi Electric Evolution+ s-MEXT Technical Manual

17.13.4 Remote keyboard from 200 metres up to 500 metres

If the remote keyboard must be installed over 200m away from the local network (LAN), a power unit must be installed near the
remote keyboard.
The remote keyboard cannot be installed more than 500 m away.
The only difference between this and a remote keyboard up to 200 metres is the connection of the power unit to terminals 1 and
2 of the T shunt (the one near the remote keyboard). In this case a 3-wire cable connecting the two T-shunts is sufficient.
If just one chiller is connected, the connection diagram is:
