The Turbo-V controller is equipped with a 3-wire power
cord and plug (internationally approved) for user safety.
Use this power cord and plug in conjunction with 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:

To connect the controller to the pump use the specific
cable supplied with the controller.
The controllers model 969-9424 and 969-9524 are
supplied with the pump cable fixed to the controller rear
