1.3 PRELIMINARY RECOMMENDATIONS

DANGER!
Always disconnect the general power supply before changing any electric
component associated to the inverter. Many components may remain loaded
with high voltages and/or moving (fans), even after the AC power supply input is
disconnected or turned off. Wait for at least ten minutes in order to guarantee the
full discharge of the capacitors. Always connect the grounding point of the inverter
to the protection grounding.
DANGER!
Débranchez toujours l'alimentation principale avant d'entrer en contact avec un
appareil électrique associé au variateur. Plusieurs composants peuvent rester
chargés à un potentiel électrique élevé et/ou être en mouvement (ventilateurs), même
après la déconnexion ou la coupure de l'alimentation en courant alternatif. Attendez
au moins 10 minutes que les condensateurs se déchargent complètement. Toujours
connecter le point de mise à la terre du variateur sur la mise à la terre de protection.
NOTES!
Frequency inverters may interfere in other electronic equipment. Observe the
„
recommendations of
11 in order to minimize these effects.
Read the entire manual before installing or operating this inverter.
„
Do not execute any applied potential test on the inverter!
ATTENTION!
The electronic cards have components sensitive to electrostatic discharges.
Do not touch the components or connectors directly. If necessary, first touch the
grounding point of the inverter which must be connected to the protection ground
or use a proper grounding strap.
DANGER!
Crushing Hazard
In order to ensure safety in load lifting applications, electric and/or mechanical
devices must be installed outside the inverter for protection against accidental
fall of load.
