Specifications of wiring

Notes:

Flexible wire is recommended because the wire needs to be bent during installation, otherwise

•

it will produce installation problem.
Data in the following table only correspond to the stranded copper core ﬂ exible wire. If other

•

wire will be chosen, please refer to the electrical engineering handbook in accordance with the
wiring current provided in the table.
For the safety of the unit, wiring shall not be based on the rated current, because the operating

•

conditions will change with the season.
