23. ELECTRICAL WIRINGS

NXW chillers are completely wired in the factory and only need the connection to the electricity mains supply, down- stream from a group switch, according to the regulations in force in the coun- try where the machine is installed.

It is also suggested to check:

− the mains supply characteristics, to ensure it is suitable for the levels indicated in the electrical data table, also taking into considera- tion any other equipment that may be operating at the same time.

− The unit is only powered after the last (hydraulic and electric) instal- lations.

− Follow the connections instructions of the phase conductors, and earth.

− The power supply line will have a special protection upstream against short circuits and earth losses that sections the system ac- cording to other users.

− The voltage should be within a tolerance of ± 10% of the rated supply voltage of the machine (for Three-phase units displacement max 3% between the phases). If these pa- rameters are not respected, contact the energy supplier. For electrical wirings use isolated double cables according to the standards in force in the different countries.

− It is necessary to use a omnipolar thermomagnetic switch, in compli- ance with the CEI-EN standards (contact opening of at least 3 mm), with adequate switch capa- bility and differential protection based on the followed electrical data table, installed as close as possible to the machine.

− It is necessary to carry out an effi- cient earth connection. The manu- facturer can not be held responsi- ble for any damage caused by the failure and ineffective earthing of the machine.

− For units with Three-phase power

check the correct connection of the phases.

WARNING:

It is forbidden to use water pipes for the earthing of the machine.

23.1. RECOMMENDED SECTION OF ELECTRIC CABLES

The cable sections indicated in the ta- ble are advised for a maximum length of 50 m.

All electrical operations must be carried out BY QUALIFIED PERSONNEL, IN ACCORDANCE WITH THE CORRESPONDING REGULATIONS, trained and in- formed about the risks related to such operations.

The characteristics of electric lines and related components must be estab- lished by PERSONNEL AUTHORISED TO DESIGN ELECTRIC INSTALLATIONS, fol- lowing international regulations and the national regulations of the country in which the unit is installed, in compliance with the legislative regulations in force at the moment of installation.

For installation requirements, the wiring layout supplied with the unit must be compulsory referred to. The wiring layout together with the manuals must be kept in good conditions and readily ACCESSIBLE FOR FUTURE OP- ERATIONS ON THE UNIT.

IT is compulsory to check the machine sealing before connecting the elec- trical wirings. The machine should only be powered once the hydraulic and electric operations are completed.

ELECTRICAL DATA VERSION WITH PUMPING GROUP (ALL VERSIONS)

For higher lengths or differ- ent types of cable installa- tion, it will be the DESIGNERS responsibility to carefully measure the line main switch, the supply power line and the earthing protection connection, and the work- ing connection cables:

− the length

− the type of cable

− Absorption of the unit and its physical position, and room temperature.

WARNING:

Check that all power cables are correctly secured to the terminals when switched on for the fi rst time and after 30 days of use. Afterwards, check the connection of the power cables every six months.

Slack terminals could cause the cables and components to overheat.

23.2. CONNECTION TO THE POWER SUPPLY

− Check there is no voltage on the electric line you want to use.

23.2.1. To access the elec- tric box:

− Turn the electrical panel screws ¼ in counter- clockwise direction

− Turn the handle of the door-block disconnecting switch to OFF (see figure).

In this way, the electrical panel can be accessed

23.3. ELECTRICAL POWER CONNECTION

− For the functional connection of the unit, run the power supply cable to the electrical panel inside the unit fi g. 1 and connect it to the disconnecting switch terminals ob- serving the phase and the earth. fi g. 2

23.4. AUXILIARY CON- NECTIONS AT THE USER/INSTALLER EXPENSE

For installation requirements, refer to the wiring diagram supplied with the unit. The wiring diagram together with the manuals must be kept in good conditions and readily ACCESSIBLE FOR FUTURE OP-

ERATIONS ON THE UNIT. Key fig. 2

24. CONTROL AND FIRST START-UP

24.1. PREPARATION FOR COMMISSIONING

Bear in mind that a free start-up service is offered by the Aermec Technical Service for the unit of this series, at the request of Aermec customers or legitimate owners and in ITALY only.

The start-up must be previously agreed on the basis of the system implementation times. Before the intervention of the AERMEC After Sales Service, all the operations (electrical and hydraulic hook ups, loading and breather from the system) must be completed.

Before starting the unit make sure that:

− All the safety conditions have been respected

− The unit has been properly fixed to the support base

− The minimum technical spaces have been observed;

− Water connections have been performed respecting the input and output

− The hydraulic system has been loaded and vented.

− The hydraulic circuit taps are open

− The electrical wirings have been properly carried out;

− The voltage is within a tolerance of 10% of the unit rated voltage

− The earthing has been carried out correctly

− Tightening of all electrical and hydraulic connections have been well carried out.

24.2. FIRST COMMISSIONING OF THE MACHINE Before activating the unit:

- Close the electric panel lid.

- Position the door-block disconnecting switch of the machine on ON, turning the handle down. (fig.3)

- The display on (fig.4) indicates that the unit is ready for operation.

For more information see the USER'S MANUAL 24.3. SEASON CHANGEOVER

For the season changeover, see the user's manual.

WARNING

The fi rst start-up has to be carried out with the standard settings, only when the test is fi nished the values of the opera- tion Set Point vary.

Before starting up, power the unit for at least 12-24 hours

by positioning the pro- tection thermomagnetic switch and the door-block disconnecting switch on ON fi g.1

Make sure that the control panel is turned off until it allows the oil heater system the compressor casing.
