Decommissioning - WEG CFW900 Serie Manual De Seguridad

6 DECOMMISSIONING

For decommissioning, the machine or system shall preferably be switched off from any type of
energy supply. If this is not possible, all electrical connections (power and control) of CFW900
must be switched off prior to any decommissioning activity on the equipment.
DANGER!
Before decommissioning, it is necessary to make an analysis of the safety
of the machine or the system. Hanging loads, brakes or rotating parts may
require energy to stay in a safe state and the power removal can lead to unsafe
conditions. Make sure that power removal can be realized in a safe way.
DANGER!
Always disconnect the general power supply before touching any electrical
„
component associated with CFW900.
Many components may remain charged with high voltages (e.g. capacitors)
„
and/or moving (e.g. fans), even after the power supply input is disconnected
or turned off.
Wait for at least ten minutes so as to guarantee the full discharge of the
„
capacitors.
Always connect the equipment to the protective earth (PE) at the appropriate
„
point.
