Only qualified electricians can install and start-up the inverter.
Primary and ambient conditions
Make sure that the mechanical and electrical installation of the inverter is correct. Refer to section
Installation checklist on page 51.
Make sure that the insulation of the assembly is sufficient. Refer to section Insulation test on page 39.
If the insulation is not sufficient, the optional insulation resistance monitoring cannot be tuned properly.
Make sure that the ambient conditions for start-up, temperature, humidity, altitude etc. are within the
limits. Refer to PVS800-57B central inverters hardware manual (3AXD50000048300 [EN]).
Set up the cabinet heater: Set the maximum temperature settings of the thermostats according to the
schematic drawings.
If the inverter is installed in a very humid environment, and there is a delay before commissioning
without auxiliary power, use the cabinet heaters for several days before you do the commissioning.
