without supervision.
▪ Make up the power supply in
accordance with IEC60335-1, via a
separator device which exhibits
contact separation in all poles with a
contact opening distance that provide
full disconnection in accordance with
overvoltage categoryIII.
▪ All the electrical work must only be
carried out by electrically qualified
experts and with consideration of the
local and national regulations, and
the instructions in this manual. Check
that a suitable electrical circuit is
being used. Inadequate capacity of
