Delta Vfd B Operating Manual
Thank you for choosing DELTA’s high-performance VFD-F Series. The VFD-F Series is manufactured with high-quality components and materials and incorporates the latest microprocessor technology available. Getting Started. This quick start will be helpful in the installation and parameter setting of the AC motor drives. To guarantee safe operation of the equipment, read the following safety guidelines before connecting power to the AC motor drives.
For detail information, refer to the VFD-F User Manual on the CD supplied with the drive. 1.AC input power must be disconnected before any wiring to the AC motor drive is made. 2.A charge may still remain in the DC-link capacitors with hazardous voltages, even if the power has been turned off.
To prevent personal injury, please ensure that power has turned off before opening the AC motor drive and wait ten minutes for the capacitors to discharge to safe voltage levels. 3.Never reassemble internal components or wiring. 4.The AC motor drive may be destroyed beyond repair if incorrect cables are connected to the input/output terminals.
Never connect the AC motor drive output terminals U/T1, V/T2, and W/T3 directly to the AC mains circuit power supply. 5.Ground the VFD-F using the ground terminal. The grounding method must comply with the laws of the country where the AC motor drive is to be installed. Refer to the Basic Wiring Diagram. 6.VFD-F series is used only to control variable speed of 3-phase induction motors, NOT for 1- phase motors or other purpose.
