Electrical Review

Confirm that the DCF and electrical schematics have the same incoming power. (Phase and Voltage)

Compare physical build to electrical schematics

  • Follow the schematics line by line to verify:
    • Wire size/color
    • Wire tag
    • Device tag/component
    • Breaker size
    • Terminal designations
  • During review observe:
    • Wire terminations for proper crimping
    • Components are secure
    • Cleanliness
    • General appearance

Check brake circuit (Is power coming from general 24v or from safety relay output)

Compare VFD and Drive Voltage against incoming power

Before powering on the panel make sure B2 and B3 are jumped on the drives (Not needed if resistors are connected to B1 B2)

UPS Battery Backup

  • Install fuse before power up
