INSTALLATION

Ensure that the main power supply specifications corresponds to the voltage specified on the data plate of the electrical panel and motor connected, then make the earthing connection before all other connections.

• QEM ➞ 230V ± 10% 50Hz
• QET ➞ 400V ± 10% 50Hz

The power line must be protected by a residual current circuit breaker. Tighten the electrical cables on the relative terminals using a suitable tool correctly sized to avoid the risk of damage to the fixing screws. Take care if using an electric screwdriver.

LUMINOUS INDICATORS AND CONTROL COMMANDS
QEM
By turning the main switch to position (1), the control box starts the pump and turns on the green led. The pump will remain in operation until the main switch is not turned in the position (0).
If an overload occurs in the water pump’s motor, the intervention of the thermal protection stops the pump and turn off the led. The intervention of the protection is showed when the thermal protection button drops out. To restore the functioning of the control box after the intervention of the protection press the button down.

QET
By turning the main switch to the MAN position, the control box starts the pump in manual mode. green led goes out indicating that the water pump is running. The pump will remain on until the main switch is not turned to the 0 position.
By turning the main switch to the AUT position, the control box activates the pump only if the contact wired to the P-P terminals is closed. The pump will remain on until the main switch is not turned to the position (0) or until P-P contact is not opened.
The amperometry relay will stop the water pump during a situation of overloading of the motor. It will turn off the green led and the red led goes out to show the tripping. To restore the operation of the control box after the intervention of the protection, turn the main switch to position (0), open the control box, and press down the RESET button.
The automatic reset of the protection can be set by pressing down the reset button and turning it ¼ turn clockwise (not recommended).
