IMPORTANT REMARKS
V2 has the right to modify the product without previous
notice; it also declines any responsibility to damage or
injury to people or things caused by improper use or wrong
installation.
• This instruction manual is only for qualified technicians, who
specialize in installations and automations.
• The contents of this instruction manual do not concern the end
user.
• Every programming and/or every maintenance service should
be done only by qualified technicians.
• The installer must provide for a device (es. magnetotermical
switch) ensuring the omnipolar sectioning of the equipment
from the power supply. The standards require a separation of
the contacts of at least 3 mm in each pole (EN 60335-1).
• After making connections on the terminal board, use one
hose clamp to fix dangerous voltage wires near the terminal
board and another hose clamp to fix safety low voltage wires
used for accessories connection; this way, in case of accidental
detachment of a conducting wire, dangerous voltage parts will
not come into contact with safety low voltage ones.
• The plastic case has an IP55 insulation; to connect flexible or
rigid pipes, use pipefittings having the same insulation level.
• Also the automation upstream electric system shall comply with
the laws and rules in force and be carried out workmanlike.
The MISTRAL sensor detects the wind speed and transmits
this parameter to the connected controller by cable.
To install MISTRAL, carefully read these instructions.
