4. The connection of meter and outdoor unit
In the above figure 485A connects to the O terminal of power meter. 485B connects to A terminal of power meter. The
length of communication wire should less than 100m. Communication cable is isolated to high voltage.
Important points:
(1) The power meter is customized by Midea, it has been set to the percentage of 30:1, and if it is bought from the market,
it cannot be used normally.
(2) DTS634-M meters' current specifications:
1.5 (6) A is used with BH-0.66-30IB current transformer, and the current specifications will change into: 45 (180) A, so the
power meter's maximum current is 180 A.
(3) We only offer DTS634-M power meter and BH-0.66-30IB current transformer. The connection line from current
transformer output to the electricity meter should be offered by installer. We suggest that the line diameter should
≥2.5mm².
