High Performance Universal Inverter

www.veikong-electric.com

Foreword

Thanks for your choosing VFD700-PV solar pump drive .

VFD700-PV solar pump drive is developed for the supply of PV water pumps based on

VFD700, which has the maximum power point tracking ability, dormant at weak light, wake

up at strong light, high water level dormant, under load pre-warning and other control

protection functions can ensure normal operation of water pumps according to the customers’

requirements to switch to grid power supply.

Please read this manual carefully, and save the manual, make sure that the end customer

has the manual.

Warnings, Cautions and Notes

A Warning contains information, which is essential for avoiding a safety hazard.

A Caution contains information, which is necessary for avoiding a risk of damage to the

product or other equipment.

A Note contains information, which helps to ensure correct operation of the product.

WARNING

 The VFD700-PV Solar pump drive should ONLY be installed by a qualified electrician.

 Install the drive far away from the inflaming materials like metal sheet in case of fire.

 Do not install the drive in environment with explosive gas.

 Even when the motor is stopped, dangerous voltage is present at the Power Circuit

terminals L1、L2、L3 、U、 V、 W, and depending on the frame size, +DC and

−DC, or BR.

 Dangerous voltage is present when input power supply is connected to the drive. After

disconnecting the supply including PV input, wait at least 10 minutes (to let the

intermediate circuit capacitors discharge) before removing the cover.

 PE terminals must be earthed very well.

CAUTION

 The VFD700-PV is not a field repairable unit. Never attempt to repair a malfunctioning

unit; contact the factory or your local Authorized Service Center for replacement.

 The VFD700-PV will start up automatically after an input voltage interruption if the

external run command is on.

 Prior to measurements on the motor or the motor cable, disconnect the motor cable from

the solar drive.

 Before connecting the solar pump drive to mains, make sure that the VFD700-PV’s front

covers are closed.

NOTE:

 The selection of fuse and switch refers to table 2-4.

 Do not suggest using the power contactor to control the RUN/STOP of the drive.

 In default carrier frequency, the maximum motor cable length is 100 meters.

When the motor cable is longer than 100m, recommend to use output reactor.

 For safety, drive and motor must be earthed, and the earth contacting resistance

must be less than 10Ω, the earthing conductor must meet the requirements in

table 2-5.
