Power circuit and cable requirements

A power circuit (see table below) must be provided for connection of
the unit. This circuit must be protected with the required safety
devices, i.e. a main switch, a slow blow fuse on each phase and an
earth leak detector.

When using residual current operated circuit breakers, be sure to use
a high-speed type 300 mA rated residual operating current.

Be sure to install a main switch for the complete system.

7.3.

General

Up to 3 units can be connected by crossover power source
wiring between outdoor units. However, units of smaller capacity
must be connected downstream. For details, refer to the
equipment design data and technical data.

When connecting several units in VRV+ combination, the power
supply of each outdoor unit can also be connected separately.
Refer to the field wiring on the engineering data book for further
details.

Make sure to connect the power source wire to the power
source terminal block and to clamp it as shown in 

figure 14

,

chapter "Field line connection".

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.

Keep power imbalance within 2% of the supply rating.

Large imbalance will shorten the life of the smoothing capacitor.

As a protective measure, the product will stop operating and an
error indication will be made, when power imbalance exceeds 4%
of the supply rating.

Follow the "electrical wiring diagram" when carrying out any
electrical wiring.

NOTE

Use copper conductors only.

When using the adaptor for sequential start, refer
to 

"7.4. Examples" on page 13

.

For connection wiring to outdoor-outdoor
transmission F1-F2, outdoor-indoor transmission
F1-F2, outdoor-multi transmission Q1-Q2, refer to

"7.4. Examples" on page 13

.

For connection wiring to the central remote
controller, refer to the installation manual of the
central remote controller.

Use insulated wire for the power cord.
