5.1
Safety
Risk of injury due to electric shock
• The inverter must be installed only by trained and authorized
electricians.
• All electrical installations must be done in accordance with the
National Wiring Rules standards and all locally applicable standards
and directives.
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
of the inverter. Touching the DC conductors or the live components
can lead to lethal electric shocks. If you disconnect the DC connectors
from the inverter under load, an electric arc may occur leading to
electric shock and burns.
•
Do not touch non-insulated cable ends.
•
Do not touch the DC conductors.
•
Do not touch any live components of the inverter.
•
Have the inverter mounted, installed and commissioned only by
qualified persons with the appropriate skills.
•
If an error occurs, have it rectified by qualified persons only.
•
Prior to performing any work on the inverter, disconnect it from all
voltage sources as described in this document(see Section 9
"Disconnecting the Inverter from Voltage Sources").
