Connection to photovoltaic panels
Remember that photovoltaic panels produce a current while they are illuminated. Be
sure to check that cables are not live.
NOTE! Wrongly connected cables may damage the equipment.
Run the solar panel cables to the respective terminals on the drive through the bottom of the supply
unit (see Figure 5-5 and Figure 5-6). Check for the cable sizes and the appropriate number of cables
in tables on page 20.
In drives NXV0050 and NXV0100, always connect the two cables on both sides of the terminal bar
(see Figure 5-6).
Connect the positive pole of the photovoltaic panel to the terminal marked with ‘+’ and the negative
pole to the terminal marked with ‘-‘.
