corrispondano con quelli della linea di alimentazione.
In particolare si sottolinea che il collegamento a triangolo è sempre relativo al valore più basso delle due tensioni di alimentazione possibili,
viceversa per il collegamento a stella, ed il rapporto fra le due tensioni è pari a 1,73.
Per i motori con tensione di targa 230/400V o 400/700V è ammesso uno scostamento del ±10% della tensione di alimentazione in quanto possono
essere utilizzati anche alle tensioni di 220 e 240, 380 e 415V ± 5%.
Senso di rotazione.
ATTENZIONE Un eventuale errato senso di rotazione può comportare il danneggiamento del gruppo poichè la potenza assorbita e la spinta

4 STORAGE AND HANDLING:
Store the product in a dry and dust-free place.
Avoid instability which could be used by wrongly positioning the product.
Turn the rotating parts at regular intervals to prevent them from jamming (consult paragraph 5.1 “Preliminary inspections” for the relative procedure).
ATTENTION For safe storage after a previous installation, the pump must be thoroughly cleaned with water (never ever use hydrocarbon based
products for this purpose) and dried inside with a jet of forced air.
The product must be handled with care and caution. Use suitable lifting means in compliance with the safety provisions in merit.

ATTENTION Make sure that the voltage and frequency ratings on the data plate of the electric motor correspond to those of the electricity main.
Ensure that the appropriate connection either star or delta is selected to suit the power supply.
In particular, remember that the delta connection always refers to the lower value of the two possible voltage ratings. Vice versa for star connections.
The ratio between the two voltage ratings is 1,73.

Rotation direction.
ATTENTION A wrong rotation direction could damage the pumping unit since the power draw and axial thrust of the pump could be considerably
higher than the forecast values.
Identify the exact rotation direction (clockwise for the pump shaft when viewed from the coupling side or for the electric motor, if
installed, when viewed from the fan side) by proceeding with the following operations:

3) if the rotation direction is wrong, disconnect the power source and switch two of the three phase wires with each other.
3KDVHXQEDODQFH.
Check the power draw on each phase wire. Unbalances should not exceed 5%.
Higher values could be caused by the motor and/or the electricity main. Check the power draw in the other two motor-main connection
combinations, making sure that the same rotating direction is maintained.
The optimum connection is that with the least difference in power draw between the phases. Note that if the higher power draw is
always on the same line phase, the main cause of unbalance will be due to the power main.
6 USE AND MANAGEMENT
 6WDUWLQJ:
It is forbidden to set the machine at work unless all the protections with which it must be equipped in order to comply with the safety
requirements, have been correctly installed.
ATTENTION - the pump is supplied without oil (excluding models MEC...HT). Add lubricant to the pedestal before starting (the procedure is
 GHVFULEHGLQVHFWLRQµ0DLQWHQDQFH¶
- the unit must operate in a horizontal position to ensure that both bearings are lubricated.
- before starting, always prime the pump, venting off the air in the pipe and in the pump itself.
Comply with the following instructions if the pump is not installed below water level:

If the unit is unable to start (no “run-up”), do not persist as this would only damage it. Identify and eliminate the malfunction.
If an indirect starting system is used, the starting transient must be brief and must never last more than a few seconds.
General prescriptions for employ of INVERTER
When starting and/or during use, the minimum frequency must not be less than 70% of the rated value.
The motor must be ordered with the type of electric winding that suits the use required.

General instructions for use of the SOFTSTARTER:
- The SOFTSTARTER device must be the voltage ramp and not the current ramp type.
- Always make sure that the softstarter is cut out once the starting phase of the assembly has terminated.
- Minimum inrush voltage Vs = 60 % Vn.
- Maximum acceleration time 4 s.
