PV arrays will produce electrical energy when exposed to sunlight and
thus can create an electrical shock hazard.
Wiring of the PV arrays should only be performed by qualified
personnel.
All cables must be firmly attached, undamaged, properly insulated and
adequately dimensioned.
During Inverter Operation
Do not open the enclosure when the inverter is under voltage. There is an
unlikely but possible risk of explosion in very specific cases of fault. The
housing will protect persons and property from such an explosion, only if it is
correctly sealed.
There is a risk of inverter damage or personal injury!
Do not disconnect DC connectors while the inverter is under AC load!
First de-energize the equipment from dual power sources and then
verify that there is no voltage present.
There is a risk of burn!
Prevent from touching device hot parts (such as heat sink) during
operation. Only LCD display panel and DC switch can be touched
during inverter operation.
Maintenance and Service
There is a risk of inverter damage or personnel injury due to incorrect
service work!
Always keep in mind that the inverter is power supplied by dual power
source: PV arrays and utility grid.
Before any service work, you should obey the following procedures.
Disconnect inverter from the utility grid side first and then PV arrays;
Wait at least ten minutes until the inner capacitors discharge
completely;
Verify that no voltage or current present with appropriate testing
device.
Keep unrelated person away!
A temporary warning sign and barrier must be posted to keep
non-related person away while performing electrical connection and
service work.
Any fault that may impair the inverter safety functions must be
repaired immediately before the inverter is restarted.
Inverter contains no owner serviceable parts inside. Please contact
local authorized personnel if any service work is required.
Servicing of the device in accordance with the manual should never
be undertaken in the absence of proper tools, test equipment or
more recent revision of the manual which is clearly and thoroughly
understood.
