Before installing a VFD, the equipment manual and the labels on the VFD are two sources of information to consult. Which statement is true?

• A. True
• B. False
• C. It depends on the model
• D. Not necessary

Answer: (A)

Both sources should be checked before installing a VFD because they provide complementary, essential guidance for a safe and correct installation. The labels on the drive show the exact electrical ratings, terminal assignments, and any unit-specific cautions you must follow. The equipment manual supplies the full installation procedure, wiring diagrams, grounding and cooling requirements, enclosure considerations, and recommended parameter settings for your motor and control setup. Relying on only one source can lead to miswiring, overrated or undersized connections, or missing safety protections. By consulting both, you ensure you apply the correct wiring, protections, and settings for that particular model and application.
