Particular warnings

Always switch off the mains power supply before working on the electrical or
mechanical part of the system. Wait for the warning lights on the control panel to go
out before opening the appliance. The capacitor of the direct current intermediate
circuit remains charged with dangerously high voltage even after the mains power has
been turned off.
Only firmly cabled mains connections are admissible. The appliance must be earthed
(IEC 536 class 1, NEC and other applicable standards).
Mains terminals and motor terminals may still have dangerous voltage when the motor
is stopped.
If the power cable is damaged, it must be replaced by the technical assistance service
or by qualified personnel, so as to avoid any risk.
