6.3 Switching off the inverter
DANGER
■ Even when the DC isolating switch is switched off, the components and connec-
tions of the inverter are still live!
■ After disconnecting the inverter wait at least 5 minutes before opening the device
to permit internal capacitors to discharge.
■ The MC connector (DC input), may only be separated from the inverter if the
DC isolating switch is open. Otherwise, disconnecting the DC feed lines during
operation can result in dangerous arcs.
