2.2 Safety Information
Danger to life from electric shock due to live voltage
High voltages are present in the live components of the DC sub-distribution. Touching live
components results in death or serious injury due to electric shock.
• Wear suitable personal protective equipment for all work on the product.
• Do not touch any live components.
• If live voltage is not absolutely necessary, disconnect all DC sub-distributions before working
on the DC sub-distribution and disconnect the inverter on the DC side (see manual of the DC
sub-distribution and of the inverter).
Danger to life due to high voltages on DC conductors
When exposed to sunlight, the PV array generates dangerous DC voltage which is present in the
DC conductors. Touching the DC conductors results in death or serious injury due to electric
shock.
• Cover the PV modules.
• Do not touch the DC conductors.
Danger to life due to electric arc
An electric arc may occur when plugging or removing the DC connectors or the inline fuse
connectors under load and in case of a reverse-poled connection of the DC connectors. Electric
arcs can result in death or serious injury.
• Ensure the correct polarity of the strings before connection.
• Plug or remove DC connectors and inline fuse connectors only under load-free conditions.
• Disconnect the DC sub-distribution (see the DC sub-distribution manual).
• Wear suitable personal protective equipment.
Damage to the PV system due to incorrectly rated fuses
If fuses are incorrectly rated, excessive reverse currents can destroy the PV modules.
• Observe the maximum current values for the product when rating the fuses.
Damage to the DC connectors due the use of contact cleaner of other cleaning agents
Some contact cleaners or other cleaning agents may contain substances that decompose the
plastic of the DC connectors.
• Do not use contact cleaners or other cleaning agents for cleaning the DC connectors.
