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
page 11
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.
