EPIC-A In size 2 devices, the ground connection between the base and the power is made by means of four metal pins on the power side that engage into four special holes on the base with spring contacts. At the same time, these metal pins serve as a guide for a correct coupling between the base and the heat sink.
Page 36
EPIC-A DANGER Be careful not to damage or remove the four metal pins, as this will not only compromise the mechanical coupling between the base and the power, but also the ground connection. 6.4. Assembly on-board the motor The device may be installed in place of the motor terminal box cover both horizontally and vertically.

EPIC-A 10.2. The pressure vessel In water systems equipped with inverters, the function of the pressure vessel is to compensate for losses (or minimum water consumption) and maintain pressure when the pump is stopped, thus avoiding excessively frequent start/stop cycles. It is of fundamental importance to correctly choose the volume and the pre-charge pressure of the pressure vessel.
Page 63
EPIC-A A splitting method (called COMBO mode) consists in using several pumps in parallel (up to 8) each controlled by an inverter. In this case, the efficiency and reliability of the pumping unit is maximized, ensuring soft starts and stops and complete protection of the pumps.
