Output cable from drive (Shielded)
IMPORTANT
The ground cable/shield for both input and output must pass through the EMC core(s), except for the following:
• Frame E drives with internal filters where the grounded input cable must not pass through EMC CORE-E-1.
• 600V drives with external filters where the grounded output cable must not pass through the EMC core(s).
