The figures on the left show the areas subject to voltage inside the in-
verter
- Red: areas subject to input voltage (DC)
- Orange: areas subject to output voltage (AC)
- Green: areas subject to low voltage (SELV)
• Disconnect any power supplies that may be connected to the configu-
rable relay.
• The figure on the left shows the areas subject to voltage in the inverter
under normal operating conditions.
• Open the DC disconnect switch on the outside of the inverter.
• Disconnect the grid voltage (by switching off the protective device
upstream of the inverter).
Under these conditions the inverter does not have any hazardous
voltages and all areas may be freely accessed.
