Grounding Connections - WEG CFW-11 User Manual

Installation and Connection
Connection of the motor cable shield to ground: make a connection with low impedance for high
frequencies. Example in the
motor cable shield to the ground in a similar mode, with the clamp at the inverter inner part, according
to the Figure 3.17 on page

3.2.4 Grounding Connections

DANGER!
Do not share the grounding wiring with other equipment that operate with high currents (e.g. high
power motors, soldering machines, etc.). When installing several inverters, follow the procedures
presented in
DANGER!
Ne pas partager le câblage de mise à la terre avec d'autres équipements opérant avec des intensités
élevées (par ex: moteurs haute puissance, postes de soudure, etc.). Lors de l'installation de plusieurs
variateurs, appliquer les procédures présentées dans l'illustration 3.18 pour la connexion de mise
à la terre.
ATTENTION!
The neutral conductor of the network must be solidly grounded; however, this conductor must not
be used to ground the inverter.
