10.1 General information
!
C a U t i o n
•
Before any work to the electrical wiring or regular inspections, switch
off the mains power supply of the indoor and outdoor units. Wait three
minutes before starting installation or maintenance work.
•
Make sure that the interior and exterior fans have come to a complete
standstill before starting work on the electrical wiring or regular
inspections.
•
Protect cables, the drainage pipe, electrical components, etc. from
rodents and insects; otherwise these might damage unprotected
components and this could result in fire.
•
Do not allow cables to come into contact with the refrigerant pipes,
metal edges, printed circuit boards (PCB) or the electric components
inside the unit; the cables may be damaged and this could result in
fire.
10.2 General VerifiCations
1 Make sure the electric components in the installation (earth
leakage breaker, circuit breaker, cables, connectors, cable
terminals and main power switches) have been selected
correctly in line with the electrical data given in this Manual.
Also make sure that these components are compliant with
national and local codes.
a. 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.

•
Connecting the operating line cables incorrectly may lead to faults
in the PCB.
•
Firmly secure the cables inside the indoor unit with plastic flanges.

D a n G e r
•
Use an earth leakage breaker with medium sensitivity, and an
activation speed of 0.1 or less. If this is not fitted, there is a risk
of electric shock and/or fire.
•
Install an earth leakage breaker, fuse and circuit breaker for
each outdoor unit power line. Not fitting it may cause an electric
shock or fire.
b. Connect the power supply wiring for each group of indoor
units to its outdoor unit group (maximum capacity for
each group of indoor units: 26 HP). Do not mix units of
different groups.
c. For heat recovery systems, the CH-Box and the indoor
unit of the same refrigerant cycle can be supplied from
the same mains power switch.
2 Check that the supply voltage is between 90 and 110% of
the rated voltage. Where the voltage capacity is too low, it
will not be possible to start the system due to the drop in
voltage.
