INSTALLATION
!
Connection to the mains must be made in accordance
with the local law. Always connect the ground wire and
use a properly grounded power socket to avoid
electrical shock. High voltage developed in the
controller can cause severe injury or death. Before
servicing the unit, disconnect the input power cable.
The Turbo-V controller can be used as a bench unit or
a rack module, but it must be positioned so that free air
can flow through the holes. Do not install or use the
controller in an environment exposed to atmospheric
agents (rain, snow, ice), dust, aggressive gases, or in
explosive environments or those with a high fire risk.
During operation, the
conditions must be respected:
•
temperature: from O °C to +40 °C
•
relative humidity: 0 - 95% (without condensation).
To connect the controller to the pump use the specific
cable supplied with the controller.

the controller connector J16 and the pump connector.
The two connectors at the two cable extremity cannot
