Grounding Connections - WEG CFW-11 Series User Manual

Installation and Connection
Figure 3.34 - Detail of the motor cable shield connection with the power cables shielding kit (PCSx-01) provided with inverters
For frame sizes D and E, there is a provision for grounding the motor cable shield in the standard inverter
enclosure.

3.2.4 Grounding Connections

DANGER!
3
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
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.
DANGER!
The inverter must be obligatorily connected to a protective ground (PE).
Observe the following:
- Use a minimum wire gauge for ground connection equal to the indicated in
3-21
different wire gauge is required.
- Connect the inverter grounding connections to a ground bus bar, to a single ground point, or to a
common grounding point (impedance ≤ 10 Ω).
- To comply with IEC 61800-5-1 standard, connect the inverter to the ground by using a single
conductor copper cable with a minimum wire gauge of 10 mm
than 3.5 mA AC.
