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.

Figure 2- 19 Typical power connection
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.
