NOTICE
Damage through regenerative feedback
Regenerative feedback of voltage to ground by a connected or installed component can
damage the device.
Connected or built-in I/Os, for example, a USB drive, are not permitted to supply any voltage
to the device. Regenerative feedback is generally not permitted.
Use copper cables at connectors with terminal connections
Use copper (Cu) cables for all supply lines that are connected to the device with terminals,
e.g. 24 V DC power supply cables to the 24 V DC power supply connectors.
Utiliser des câbles en cuivre sur les connexions à bornes
Utilisez des câbles en cuivre (Cu) pour tous les câbles d'alimentation qui sont raccordés à
l'appareil par des bornes, par exemple les câbles d'alimentation 24 V CC sur le connecteur
d'alimentation 24 V CC.
