4.5 ELECTRICAL WIRING
1.This central controller (HYJM-S01H) requires wiring work of the power supply cable,air conditioner,and control wiring(H-NET).
2.Wiring Method.

NOTE
• The central controller may break down by an incorrect
wiring.
•
The transmission wires are required to be separated from the
power supply wiring and other electrical device
wiring. Keep at least 30cm between transmission wiring
and the power supply wiring. If the above is not secured,
put the power supply wirings and transmission wirings
into the each metal conduit tube separately. The one side
of the metal conduit tubes should be earthed for noise
reduction.

• Do not connect the power supply wiring to the terminals for
transmission. However, if the power supply wires are
connected incorrectly, the fuse of the printed circuit
board will blow out for protection. In this case, turn on the
SP1-1 pin on the printed circuit board for unfused
emergency operation.
•
Remove the earth wiring of "E" terminal securely when the
insulating capacity test or the withstand voltage test is
performed. If the above is not secured, it may cause of
breaking down of the central controller.

• In the case of power supply voltage is 200V ~ 240V, di-
verge the main power supply cables by using the pull box
as shown in the figure. (As for the power cables between
the indoor units, refer to the technical catalog, etc.).
• The electricity supply to the unit should be via an
exclusive power control switch and protective circuit
breaker, certified and installed in accordance with local
or national safety regulations.
