DANGER
Always ensure absence of voltage before starting any electrical work!
After disconnecting the drive from line voltage, wait until the indicators on the keypad
go out (if no keypad is attached see the indicators on the cover). Wait 5 more minutes
before doing any work on the connections of the BT300 Drive. Do not open the cover
before this time has expired. After expiration of this time, use a measuring equipment
to absolutely ensure that no voltage is present.
Veuillez vous assurer en toute circonstance que la tension d'alimentation est coupée
avant tout raccordement électrique.
Après avoir débrancher le variateur de la tension de ligne, vous devez attendre
l'extinction des voyants sur le panneau opérateur (si aucun panneau opérateur n'est
raccordé, voir les voyants sur le capot). Attendez cinq minutes supplémentaires avant
de commencer tout travail sur les bornes du variateur Siemens BT300. Ne pas ouvrir
le capot avant la fin de cette période d'attente. À l'expiration de cette période, utilisez
un instrument de mesure pour vous assurer qu'aucune tension n'est présente.
DANGER
Before connecting the drive to the primary input voltage make sure that the front and
cable covers of the BT300 Drive are closed.
Avant de brancher le variateur à la tension de ligne, assurez-vous que les capots
avant et de câblage du variateur Siemens BT300 sont fermés.
