INSTALLATION
!
The Turbo-V controller must be powered with 3-wire
power cord (see orderable parts table) and plug
(internationally approved) for user's safety. Use this
power cord and plug in conjunction with a properly
grounded power socket to avoid electrical shock and to
satisfy CE requirements . 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 controllers model 969-9444 and 969-9544 are
supplied with the pump cable fixed to the controller rear
panel.
See the appendix "Technical Information" for detailed
Information about the above mentioned and the other
connections, and about the options installation.
