ELECTRICAL CONNECTIONS

The electrical connections of the machine must be defined during the system design.
DANGER
The electrical connections must only be designed and
completed by personnel with precise technical competence or
skills in the field of activity.
Before proceeding, personnel must disconnect all power supply
sources, making sure that no one may inadvertently re-connect
them.
The characteristics of the power supply network must comply with the IEC 60204-1
standards and the local standards in force and be adequate for the absorption
requirements shown in the wiring diagram.
The machine must be connected to single-phase power supply and to TN(S) type three-
phase power supply.
Refer to local bylaws. Only power the system if the cooling / water (humidifier) circuit is
charged.
OBLIGATION
The electric power supply line must include a general circuit
breaker for the disconnection of the machine from the power
source.
In accordance with the IEC 60204-1 standard, the handle of the circuit breaker must be
easy to access and at a height between 0.6 and 1.9 metres from the floor. The power
supply must never be excluded, except during maintenance.

2.5.1
Use a multipole conductor with protective sheath. The cable section depends on the
maximum absorbed current of the machine (A) as shown in the dedicated wiring diagram.
For the entry of the power cables in the machine use the holes provided at the base by the
Manufacturer.
Fix the cables to the internal machine riser using cable ties. Do not touch hot or sharp
surfaces.
The power cable must not be placed into the machine cable ducts.

The sliding electrical panel also comprehends a ModBus/IF card for the installer to connect
to, in order to set the M-NET addresses.
Where the rotational Dip-Switcher can be setted:
*1 first digit of address (tens)
*2 second digit of address (units)
*3 assign each indoor unit a number from 1 to 10 (each unit must have its own address)
The only DipSwitches to be set in the electrical panel are for the M-Net addresses on the
ModBus/IF card.
