Dual supply mode 17
I v characteristics 17
Note use two poles of the changeover switch in series to ensure that the voltage applied across each pole is half of the full dc voltage 17
The i v curve is not constant since intensity and temperature changes during day time under constant temperature current changes linearly with intensity and voltage changes logarithmically with intensity since the voltage variation is small with respect to intensity changes maximum power varies proportionally with intensity 17
The solar pump inverter operates in dual supply mode either with a three phase input supply from the grid or with dc input supply from pv cells a four pole changeover switch enables switching between the two supply modes at a given time only one supply pv cell or grid will be connected to the drive 17

Connection diagram 20
Do not use an asymmetrically constructed motor cable 20
Fasten the clamping plate to the plate at the bottom of the inverter with the provided screws for frame sizes r0 r2 fasten the i o clamping plate to the clamping plate with the provided screws 20
Free space requirements 20
In back mounting fasten the inverter to the wall with screws using four mounting holes in side mounting with frame sizes r0 r2 fasten the inverter to the wall with screws using three mounting holes the inverter can also be mounted onto a din rail 20
Installing power cables 20
Make sure that the maximum cable lengths are not exceeded for detailed information see the user s manual 20
Mechanical installation 20
Route the motor cable input power cable and control cables separately 20
The maximum ambient air temperature is 50 c 122 f at the rated current the current is derated for 40 to 50 c 104 to 131 f 20
When placing inverters on top of each other in the panel or cabinet make sure that the hot air from the inverters below do not enter directly to the inverter above 20

Connection procedure 23
If the inverter power rating matches the motor power rating the inverter is ready to run if any parameter tuning such as acceleration and deceleration times maximum and minimum speeds and so on is required see acs355 user s manual 3aua0000066143 english 24
Operating instructions 24
The solar pump inverter is developed using the acs355 firmware install the inverter as defined in sections mechanical installation installing power cables and installing control cables before operating the inverter set the required parameters defined in the following steps 24

For more information see section fault logger mode in acs355 user s manual 3aua0000066143english 68
How to reset 68
Parameters 0401 last fault 0412 previous fault 1 and 0413 previous fault 2 store the most recent faults parameters 0401 409 show the inverter operation data at the time the latest fault occurred the assistant control panel provides additional information about the fault history 68
The fault history stores all the detected faults the latest faults are stored together with the time stamp 68
The following faults messages are generated by the solar pump inverter 68
The four digit code number in parenthesis after the fault is for the fieldbus communication see chapters fieldbus control with embedded fieldbus and fieldbus control with fieldbus adapter in acs355 user s manual 3aua0000066143english 68

About this chapter 71
For input fuse connection see fuse ratings in the table below refer to gg for ac and ur or gg for dc the ur fuse ratings are determined by the maximum instantaneous dc current because the fuse works fast 71
For technical specifications of acs355 drives see acs355 user s manual 3aua0000066143 english 71
Fuse ratings 71
Important select fuses with current ratings two times higher than the dc current calculated from the nominal power for gg fuses select fuses with current ratings one size smaller than the dc current 71
Technical data 71
This chapter contains the technical specifications of the solar pump inverter for example fuse ratings sizes and technical requirements it also includes the solar status word list 71
Use standard fuses with all abb general machinery drives for fuse ratings of acs355 drives refer the technical data on power cable sizes and fuses in the acs355 user s manual 3aua0000066143 english 71
The acs355 drive is an ip20 ul open or nema 1 type drive to be used in a heated indoor controlled environment the drive must be installed in clean air according to enclosure classification cooling air must be clean free from corrosive materials and 72
