WARNING
Failure to disconnect input power may cause serious injury or death.
When you connect input power to the Siemens BT300 Bypass, the motor terminals
are energized even if the motor is not running. Do not make any connections with
input power connected to the Siemens BT300 Bypass. Disconnect and lock out power
to the Siemens BT300 Bypass before servicing it.
Si vous ne coupez pas l'alimentation, vous risquez des blessures graves ou
mortelles.
Lorsque vous branchez le variateur Siemens BT300 à l'alimentation, les bornes du
moteurs sont sous tension, même si le moteur n'est pas mis en route. N'effectuez
aucun branchement si l'alimentation est raccordée au variateur Siemens BT300.
Débranchez et consignez l'alimentation avant de procéder à un entretient.
WARNING
After you disconnect input power, allow the power supply to be off for at least five
minutes so that the DC bus capacitors can discharge to a safe voltage.
Après avoir débranché l'alimentation, laissez écouler une période d'attente d'au
moins cinq minutes, afin que les condensateurs du bus DC puissent décharger en
toute sécurité.
Inspect the mechanical and electrical installation for compliance with local electrical
codes and regulations. After installation, verify that:
● Siemens BT300 Bypass and motor are properly grounded.
● Input power and motor wire sizes are correct and connections are secure.
● Control wiring is correct and connections are secure.
● Control wiring is not routed with power wiring.
● Motor wiring is not routed in the same conduit with power wiring.
● Siemens BT300 Bypass installation environmental conditions are met as follows:
– Installed in an indoor controlled environment (except NEMA 3R units) that is
free of moisture and conductive contaminants such as condensation and dust.
– Ventilation/cooling is clean and free from corrosive gases.
– Ambient temperature must be between 14°F and 104°F (-10°C to 40°C).
– Relative humidity must be between 0% and 95%, non-condensing.
