5.2 Installing Fuses for Branch Circuit Protection

Install the required, user-supplied branch circuit protection fuses according to the
applicable local, national, and international codes (e.g., NEC/CEC). The fuses must
be installed in the line before the drive input terminals. See figures 5.1 and 5.2.
Fuse value selections are provided in table 3.6.

ATTENTION: Most codes require that upstream branch protection be
provided to protect input power wiring. Failure to observe this
precaution could result in severe bodily injury or loss of life.

5.3 Installing a Required External/Separate Input Disconnect

An input disconnect must be installed in the line before the drive input terminals in
accordance with local, national, and international codes (e.g., NEC/CEC). The
disconnect should be sized according to the in-rush current as well as any additional
loads the disconnect might supply. The trip rating for the inrush current (10-12
times full load current) should be coordinated with that of the input isolation
transformer, if used. Refer to section 5.1 for additional information.
