Grounding of the IP00-protected filter
WARNING!
The filter is grounded through the four fastening screws to its mounting plate.
Ensure that the mounting plate has a proper connection to the nearest
grounding (PE) busbar/terminal. If that is not the case, use a separate
grounding conductor between the filter frame and the PE busbar/terminal.
￭
Connections to input terminals U1, V1, W1
The input terminals (U1, V1, W1) of the filter are made of aluminium. Use cable lugs
suitable for aluminium busbars and joint grease to avoid corrosion and to ensure good
electrical connection. The oxide layer must be scrubbed off from the joints before
applying the grease. ABB recommends to
• use screws included in the delivery
• retighten the connections 30 minutes after their installation.
￭
Output terminals U2, V2, W2
The output terminals (U2, V2, W2) of the filter are tin-plated copper.
