iMars grid-tied solar inverters
Safety precautions
8
z
Keep the installation site away from children and other public places.
z
Remove the metal jewelry such as ring and bracelet before installation and
electrical connection to avoid electric shock.
z
Do cover solar modules with light-tight materials. Exposed to sunlight, solar
modules will output dangerous voltage.
z
The inverter input voltage does not exceed the maximum input voltage;
otherwise inverter damage may occur.
z
The positive and negative pole of solar modules can not be grounded, otherwise
irrecoverable damage may occur.
z
Ensure the proper grounding of the inverter, otherwise, improper connection or
no grounding may cause stop of the inverter.
z
Ensure reliable installation and electrical connection.
z
When the photovoltaic generator cells are exposed to light (even if it is dim), the
generator supplies DC voltage to the inverter.
Note: iMars series grid-tied solar inverters are only for crystalline silicon solar modules.
1.2.2 Grid-tied operation
z
Only qualified electricians are allowed to operate the inverter under the
permission of local power departments.
z
All electrical connections must meet the electrical standards of the
countries/regions in which the project is located.
z
Ensure reliable installation and electrical connection before operation.
z
Do not open the cover of inverter during operation or voltage is present.
1.2.3 Maintenance and inspection
z
Only qualified electricians are allowed to perform the maintenance, inspection,
and components replacement of the inverter.
z
Contact with the local dealer or supplier for maintenance.
z
In order to avoid irrelevant personnel from entering the maintenance area during
maintenance, temporary warning labels must be placed to warn
non-professionals to enter or usefence for isolation.
z
Firstly disconnect all power supplies of the grid to the inverter before any
maintenance, and then disconnect the breakers and wait for at least 5 minutes
until the inverter is discharged before maintenance.
