• An omnipolar device for switching-off/separation of the net
(minimum opening contacts 3 mm).
• A protection against short circuits (Am fuse) and magnetothermics,
rated in compliance with the current plate.
• Possible devices against: lack of phases, electric dissipations,
lack of water, atmospheric discharges and functioning-failure
indicators.
IMPORTANT: ALL THE ELECTRIC MASSES MUST BE CONNECTED
TO THE EARTH OF THE PLANT.
8.2. CABLE CONNECTION
• Connect the mains supply cable to the connector present inside the terminal
box, as shown on fig. 4.1
• The electrical connection of the pump to the mains (230V, 50 Hz) must be
carried out with suitable standardised connecting cord
• When connecting the mains cable ensure it never comes in contact with the
casing of the device, due to the high temperatures of the casing.
Electrical connection of ER module (for Ego ER versions with control
signal 0-10V)
• The signal conductor for control signal 0-10 V should be led through a small
gland along the hydraulic housing on the electric fuse box. The conductor
should be temperature resistant at a temperature of >85°C. The polarity of
the signal conductor is not relevant. See fig. 4.1
9. USE AND RUNNING
• Before the startup, the pump must be filled with fluid and vented
• Pumps Ego (B) -/40, -/60 and -/80 do not need to be manually vented, as this
occurs automatically when the hydraulic system is being ventilated during the
start-up. The air in the pump generates noise. After a short working period
noise should disappear.
• For a proper functioning, a minimum pressure at suction must be guaranteed
(see LIMIT OF USE)
During its running, it is normal for the pump to heat up, or to be heated
by the pumped fluid - to prevent from risk of burns, it should therefore
not be touched!
• The permitted operating area around the pump is determined by the diagram
in these instructions.
10. SETTING AND OPERATION
10.1 OPERATION MODES
• Pump settings can be changed with the button on electric box top. It is
possible to choose between the following operating modes:
