As this unit is equipped with an inverter, installing a phase
advancing capacitor not only will deteriorate power factor
improvement effect, but also may cause capacitor abnormal
heating accident due to high-frequency waves. Therefore, never
install a phase advancing capacitor.
CAUTION
Be sure to install the required fuses or circuit breakers.
This equipment complies with EN/IEC 61000-3-11
that the system impedance Z
the interface point between the user's supply and the public
system. It is the responsibility of the installer or user of the
equipment to ensure, by consultation with the distribution
network operator if necessary, that the equipment is connected
only to a supply with a system impedance Z

14.3. Connecting power supply and interunit wiring
1
Strip the insulation from the wire (20 mm).
2
Connect the connection wires between the indoor and outdoor
units so that the terminal numbers match (see wiring diagram
below). Tighten the terminal screws securely. We recommend a
flathead screwdriver to tighten the screws.
