7.7 ELECTRICAL CONNECTIONS
Check out that the power supply meets the unit’s electric nominal data (tension, phases, frequency) reported on the label in the
unit’s right-side panel. Power connections have to be made in accordance to the wiring diagram enclosed with the unit and in
conformity with the national and international norms in force (providing equipment as general magnetothermic circuit breaker,
differential circuit breakers for each electric line, proper grounding for the plant, etc.). Power cables, electric protections and line
fuses have to be sized according to the specifications listed in the wiring diagram enclosed with the unit and in the electrical data
contained in the table of technical characteristics (see Paragraph 12).
WARNING: Installer has to provide a general circuit breaker (for example a magnetothermic circuit breaker) at the
beginning of unit circuit system.
WARNING: The supply voltage’s fluctuations cannot exceed ±10% of the nominal value. Should this tolerance not be
respected, please contact our technical department.
WARNING: The power supply have to respect the listed limits: failing this, warranty will terminate immediately.
Before any operation on the unit, be sure that the power supply is disconnected.
WARNING: The water flow switch (B component in the previous hydraulic circuit and factory installed) have ALWAYS
to be connected following the indications listed in the wiring diagram. Never bridge the water flow switch
connections in the terminal board. Should the water flow switch connections altered or not properly made, the
guarantee will be invalidated.
WARNING: The remote control panel is connected to the water chiller by means of no.4 wires having a 1,5 mm
2
section. The power supply cables have to be separated from the remote control wires. The maximum distance is 50m.
WARNING: The remote control panel cannot be installed in areas with strong vibrations, corrosive gases, and excess
of dirtiness or high humidity levels. Leave free the area near the cooling openings.
