8.1 Safety
DANGER!
Danger to life due to high voltages in the inverter
Before opening the inverter, observe the following:
• Disconnect the miniature circuit-breaker and secure against reconnection.
• If a multi-function relay is connected, disconnect its supply voltage and ensure that it
cannot be reconnected.
DANGER!
Danger to life due to electric shock.
If the DC connectors are pulled out without first disconnecting the ESS or switching off the
DC switch-disconnector, a dangerous electric arc can occur.
• Disconnect the ESS or switch off the DC
switch-disconnector first.
• Then, open the lower enclosure lid and
remove the DC connectors.
NOTICE!
Electrostatic discharge can damage the inverter
The internal components of the inverter can be irreparably damaged by electrostatic
discharge.
• Earth yourself before touching any components.
