Installing Power Wiring
This chapter describes how to connect 120 volt DC input power to a 1 HP or 5 HP
GV3000/SE Solar Turbine drive. Guidelines for motor lead lengths are also provided.
Please refer to instruction manual D2-3360 for complete information on wiring a
GV3000/SE drive.
4.1 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 figure 4.1. Fuse value
recommendations are provided in table 4.1.
4.2 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 instruction manual D2-3360 for additional information.
!
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.
