Renewables and use the same packing method as when it was shipped to you, or request
instruction on packing and/or packing materials from Solectria Renewables to help insure a safe

Opening the Main Enclosure
Normally the main enclosure (or disconnects) will not have to be opened for any reason by the
user. If opening the unit is necessary follow these guidelines:
WARNING:
The inverter should only be opened by qualified service technician.
WARNING:
Only open the inverter when clear and dry outside if the inverter is
outdoors.
WARNING:
Both DC and AC disconnects must be in the off position and wait 60
seconds after the LED indicators are off before opening as electrolytic capacitors on
the internal DC “bus” are discharging during this time.
•
Switch off DC disconnect
•
Switch off AC disconnect (and AC building panel circuit breaker if desired)
•
Watch until all LED indicators have been off for 60 seconds (if not already off)
•
Use a large flat screwdriver or coin to turn latches ¼ turn counter-clockwise
See Fig. 9 and “Inside the Main Enclosure You Will See” section.
