DANGER
During a ramp stop (coast stop) (see the Siemens BT300 Operator's Manual
(DPD01809), the motor is still generating voltage to the drive. Therefore, do not touch
the components of the drive before the motor has completely stopped. Wait until the
indicators on the keypad go out. (If no keypad is attached see the indicators on the
cover.) Wait an additional 5 minutes before starting any work on the drive.
Durant un arrêt en rampe (un arrêt en roue libre) (voir le Siemens BT300 Operator's
Manual (DPD01809)), le moteur continue à produire de la tension sur le variateur. Par
conséquent, ne touchez en aucun cas les composants du variateur avant l'arrêt
complet du moteur. Attendez 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 le variateur.
DANGER
Do not perform any measurements when the drive is connected to line voltage.
N'effectuer aucune mesure lorsque le variateur est raccordé à la tension de ligne.
DANGER
The earth leakage current of the BT300 Drive exceeds 3.5 mA AC. According to
standard EN61800-5-1, a reinforced protective ground connection must be ensured.
See the section Earth grounding and ground fault protection.
Le courant de fuite à la terre du variateur Siemens BT300 dépasse 3,5 mA AC. Selon
la norme EN61800-5-1, un raccordement de mise à la terre à protection renforcée
doit être mis en place. Voir la section Earth grounding and ground fault protection.
Warnings
WARNING
At power-up, power brake, or fault reset, the motor will start immediately if the start
signal is active unless pulse control has been selected for Start/Stop logic.
Furthermore, the I/O functionalities (including start inputs) may change if parameters,
applications or software are changed. Therefore, disconnect the motor if an
unexpected start can cause danger.
Lors d'un démarrage ou d'une réinitialisation, le moteur redémarrera immédiatement
si le signal de démarrage est actif, à moins que la commande à impulsion n'ait été
sélectionnée pour la logique Démarrage/Arrêt.
De plus, les fonctionnalités d'E/S (y compris les entrées de démarrage) peuvent
changer si les paramètres, les applications ou le logiciel changent. Déconnectez donc
le moteur, si un démarrage inopiné peut poser un danger.

NOTICE
The drives are suitable for use on a circuit capable of delivering not more than
100,000 rms symmetrical amperes, 600V maximum.
Grounding and Ground Fault Protection
WARNING
The Siemens BT300 Drive must always be grounded with a grounding conductor
connected to the grounded terminal marked with .
Le variateur Siemens BT300 doit toujours être mis à la terre avec un conducteur de
protection connecté à la borne de mise à la terre marquée .
The touch current of the BT300 Drive exceeds 3.5 mA AC. According to EN 61800-5-1,
a fixed connection and one or more of the following conditions for the associated
protective circuit must be met:
●The protective grounding conductor must have a cross-sectional area of at least 8
AWG (10 mm2) Cu or 6 AWG (16 mm2) Al.
or
●An automatic disconnection of the supply in case of discontinuity of the protective
grounding conductor. See Chapter 4 Power Cabling .
or
●Provision of an additional terminal for a second protective grounding conductor of
the same cross-sectional area as the original protective grounding conductor.
Table 3: Protective Grounding Conductor Cross-Section.

The values in this table are only valid if the protective grounding conductor is made of the same metal as
the phase conductors. If this is not the case, the cross-sectional area of the protective grounding conductor
must be determined in a manner which produces a conductance equivalent to that which results from the
application of this table.
The cross-sectional area of every protective grounding conductor which does not form
a part of the supply cable or cable enclosure shall, in any case, not be less than:
●14 AWG (2.5 mm2) if mechanical protection is provided, or
●12 AWG (4 mm2) if mechanical protection is not provided.
●For cord-connected equipment, provisions shall be made so that the protective
grounding conductor in the cord shall, in the case of failure of the strain-relief
mechanism, be the last conductor to be interrupted.
