COMMISSIONING
COMMISSIONING
CAUTION
Only qualified personnel are allowed to commission the drive. Read and follow the safety
instructions on the first pages of this manual.
Neglecting the safety instructions can cause injury or
death.
Ensure that there is no voltage present in the input power terminals and no voltage can be
connected to the drive inadvertently.
This chapter do not include all the tasks to be performed during commissioning, follow local and
national regulations.
For a proper commissioning, we recommend checking the following steps:
Assure the photovoltaic installation has been done according to the
project:
•
Check the photovoltaic panel data sheet, (behind the panel).
•
Check how many series and how many panels in each series
there are.
Check the compatibility of the upstream protections (circuit breaker, fuses,
etc...) that could cause an unexpected stop during the soft charge.
Assure that the DC and AC line voltages are compatible with the drive
voltage range. On the contrary, the drive could be damaged.
(For DC ranges see section 4 and check them for any radiation and
temperature condition)
Connect input, PE and output power wiring, and verify that they are
correctly installed and fastened.
