7 Opening and Closing

7.1 Safety

DANGER!
Electric shock due to high voltages in the inverter. This can result in death or
serious burns.

Before opening the inverter, observe the following:

• Ensure that no voltage is present on the AC side.
• Ensure that neither voltage nor current is present on the DC side.

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 inside the inverter.
