Safety
Protection of peo-
ple and equip-
ment The inverter is constructed and operated in the safest possible way, both in terms of instal-
lation and operation.
The inverter fulfils the role of protecting people and equipment:
a) through galvanic (electrical) isolation
b) by monitoring the grid
Galvanic (electri-
cal) isolation The inverter has a 50/60 Hz three-phase transformer that provides electrical isolation be-
tween the DC side and the grid, thus guaranteeing the highest possible levels of safety.
Monitoring the
grid In the event of abnormal grid conditions, the inverter shuts down immediately according to
national standards and guidelines and stops feeding energy into the grid (e.g. in the event
of grid disconnection, interrupts, etc.)
Grid monitoring is carried out by:
-
monitoring the voltage
- monitoring the frequency
- using over/undervoltage relays (option, depends on country setup)
- monitoring the stand alone situation
WARNING! If the equipment is used or tasks are carried out incorrectly, serious
injury or damage may result. Commissioning of the inverter may only be carried
out by trained personnel in accordance with the technical regulations. It is essen-
tial that you read the "Safety Regulations" chapter before commissioning the
equipment or carrying out maintenance work.
