Electrical Connections - Profroid QUIETOR GQH ZB190 T5TWIN H N P Notice D'instructions

The unit must be exactly level in order to avoid creating an accumulation of oil at the lowest point, in the suction and discharge pipes, or
causing vibrations.
No obstacles should be allowed to prevent air from being drawn from the coil and the fan to discharge.
Sufficient space should be allowed:
- 1 m minimum on the fan side and electrical cabinet side for servicing and maintenance operations.
- 0.7 m minimum on the coil side.
Maximum distance between condensing unit and evaporator is 25 m with solenoid valve close to evaporator.
REFRIGERATION NETWORKCONNECTION
B
EFORE ANY WORK IS DONE ON THE REFRIGERATION CIRCUIT
The piping used must be of copper refrigeration quality in accordance with PED 2014/68/EU. And EN12735-1.
All piping must be correctly supported and fixed and should in no case be allowed to restrict the piping of the condenser units.
In order to reduce vibrations of the frame and panels, compressor is disconnected to the frame by flexible mounting.

ELECTRICAL CONNECTIONS


General information
The machine is designed in accordance with EN60204-1.
Supplying cable must be connected on terminal of main switch.
Take care: voltage close to circuits and main switch.
All cabling on site must conform to the legal standards in force in the relevant countries and to EN60204-1.
Except for special operation, the nominal current must be:
- power circuit: 400V/3+N/50Hz + Earth
- control circuit: 230V/1/50Hz (pressure switches, fans speed control, crankcase heaters).
Neutral is compulsory, 230V voltage is necessary to condenser fan.

Electrical motor wiring
Electrical motors for compressors
These are designed for a direct start.
The compressor motors are fitted with an anti-short cycle mechanism allowing a maximum of 6 start-ups per hour. Timer T1
adjustment must not be modified.
ZB compressors are protected with an internal thermistor. Motor switch off when windings temperature is too high (independently of
control)
ZF compressors are protected with an external thermostat.
Electrical motors of condenser
T1 to T4 :Models equipped with 2 fan-motors 450 or 500mm diameter
The motor fitted in the condenser is single phase.
Motor applications :
- Insulation class F
- Protection factor IP44 minimum
- Nominal current 230V.
T5 :Models equipped with 2 fan-motors 630mm diameter
The motor fitted in the condenser is single phase.
Motor applications :
- Insulation class B
- Protection factorIP54
- Nominal current 230V.
The motor protections must conform to legal standards and calibrated to the nominal current.
Fan speed control
The notice of speed controller is attached to present document into the unit
ADDITIONAL SAFETY CONTROLS
 SafetyFeatures
The safety switches fitted to the compressors must cut off the compressor instantaneously.

Crankcase heater
The crankcase heater must be powered and operational during compressor shut-downs.
,
THE HOLDING CHARGE MUST BE REMOVED
