Electrical Protections
IMPORTANT: A main switch must be installed before the
control panel of the unit, within 3 metres and in visible
position. This switch must include a protection (fuses or
automatic) and must comply with existing regulations.
Fuse type, if used, must be rapid. If automatic switch are used,
the characteristic curve for their triggering must be of type "
K
"
or “D
" or "
C
", with breaker current
Id ≥ 300mA
.
Automatic switches with "A" or "B" trigger curve are not
allowed since they are not suitable for electrical motor
protection. Residual-current device with
Id=30mA
are not
suitable for being used with inverter. Residual-current
devices must be of type "B".
CABLES
High voltage (230 V / 400 V) and low voltage cables can be
housed in the same conduit by using double-insulated cables.
