YASKAWA GPD315/V7-4X Technical Manual page 10

Parameter n012 must be set to proper motor voltage.
Always ground the Drive using its ground terminal (
circuit output terminals). See paragraph 1.4A, "Grounding".
Never connect main circuit output terminals T1 (U), T2 (V) & T3 (W) to AC
main circuit power supply.
When Drive is programmed for auto-restart ( n082 = " 1 " thru " 10 "), the
motor may restart unexpectedly — personal injury may result.
Enclosed wall-mounted type (NEMA1)
When mounting units in an enclosure, remove the top, bottom and terminal covers.
Install a cooling fan or some other means to maintain the air entering the enclosure
below 113°F (45°C).
Water and dust tight type (NEMA 4x/12)
• Never submerse this model in water.
• For the cable lead-in section (at the bottom cover), use a waterproof cable gland.
• After completion of wiring, mount the front cover and bottom cover with care
so as not to damage the gasket.
• The front cover mounting screws and bottom cover mounting screws are of
stainless. Replacements must be of stainless and the same length.
• Wiring should be performed only by qualified personnel.
• Always ground the Drive using ground terminal (
• Verify that the rated voltage of the drive matches the voltage of the incoming power.
• Never connect main circuit output terminals T1, T2, and T3 to AC main circuit power supply.
• All parameters have been factory set. Do not change their settings unnecessarily.
• Do not perform a "HIPOT" or withstand voltage test on any part of the Drive. Equipment uses semi-
conductors and is vulnerable to high voltage.
• The Control PCB employs CMOS ICs which are easily damaged by static electricity. Use proper
electrostatic discharge (ESD) procedures when handling the Control PCB. Never touch the printed
control board (PCB) while the main input power is turned on.
• Any modification of the product by the user is not the responsibility of the manufacturer, and will void
the warranty.
• Do not remove the Digital Operator or change dipswitch SW2 or rotary switch SW1 unless the main
input power is turned OFF.
• Some drawings in this manual are shown with the protective covers and shields removed, in order
to describe detail with more clarity. Make sure all covers and shields are replaced before
operating this product.
• This manual may be modified when necessary because of product improvement, modification, or
changes in specifications.
