3. UNIT INSTALLATION
3.1.- PRELIMINARY RECOMMENDATIONS
The unit installation and the maintenance operations must only
be carried out by authorised and qualified personnel.
In order to use the unit safely, it is critical that individuals who
handle it follow the safety measures set out in the standards of the
country where it is being used, use the necessary personal
protective equipment, and pay attention to the various warnings set
forth in this instruction manual.
Incorrect installation or configuration of the unit could cause serious
damage to the unit itself and to other devices of the installation.
Disconnect the main switch before starting any maintenance
task on the active filters.
The unit has DC and AC capacitors. Before starting any
maintenance, wait 5 minutes and check that there is no residual
voltage in the capacitors.
Make sure the unit is properly earthed before powering up. Any
fault in the earth connection might cause a risk of electrocution to
the user and damage to the unit itself in the case of lightning or
other transients.
Before operating on the current transformers, make sure the
secondary is short circuited. Never open a current transformer
secondary under load.
