6 Electrical Connection
WARNING!
All electrical installations must be carried out in accordance with all
applicable Local and National Codes.
Before connecting the inverter to the grid, contact your local grid
operator. The electrical connection of the inverter must be carried
out by qualified persons only.
DANGER!
Danger to life due to high voltages of the PV array
When exposed to sunlight, the PV array generates dangerous DC
voltage which is present in the DC conductors and the live
components which can lead to lethal electric shocks. If you unplug
the terminal plate with the connected DC conductors from the DC-in
slot under load, an electric arc may occur, which can cause an electric
shock and burns.
Do not touch non-insulated conductors.
Do not touch the DC conductors.
Do not touch any live components of the inverter.
WARNING!
Damage to seals on the enclosure lids in subfreezing condition
If you open the enclosure lids of the wiring box when
temperatures are below freezing, the enclosure lid seal could be
damaged. As a result, moisture can get into the wiring box.
Only open the enclosure lid of the wiring box if the ambient
temperature is at least 32
℉
(0
℃
) and there is no frost.
WARNING!
Damage to the inverter due to electrostatic discharge
Touching electronic components can cause damage to or
destroy the inverter through electrostatic discharge.
Ground yourself before touching any component.
WARNING!
Damage to the inverter due to moisture ingress during
installation
Never open the inverter when it is raining or snowing, or the
humidity is over 95%.
For attaching conduit to the enclosure, only use UL-listed
rain-tight conduit fittings or UL-listed conduit fittings for wet
locations complying with UL514B.
Seal all unused openings tightly.
