WARNING
Danger to life due to fire and
explosion
In rare cases, an explosive gas mixture can
be generated inside the product under fault
conditions. In this state, switching operations
can cause a fire inside the product or
explosion. Death or lethal injuries due to hot
or flying debris can result.
• In the event of a fault, do not perform
any direct actions on the product.
• Ensure that unauthorized persons have
no access to the product.
• Do not operate the DC load-break
switch on the inverter in case of an
error.
• Disconnect the PV array from the
inverter via an external disconnection
device. If there is no disconnecting
device present, wait until no more DC
power is applied to the inverter.
• Disconnect the AC circuit breaker, or
keep it disconnected in case it has
already tripped, and secure it against
reconnection.
• Only perform work on the product
(e.g., troubleshooting, repair work)
when wearing personal protective
equipment for handling of hazardous
substances (e.g., safety gloves, eye
and face protection, respiratory
