Danger to life from electric shock if the product is not locked
If the product is not locked, unauthorized persons will have access to live components carrying
lethal voltages. Touching live components can result in death or serious injury due to electric
shock.
• Always close and lock the product.
• Remove the keys.
• Store the keys in a safe place.
• Ensure that no unauthorized persons have access to the closed electrical operating area.
Danger to life from electric shock if the DC load-break switch is damaged
Switching the DC load-break switch at temperatures below the specified threshold may damage
the DC load-break switch. The threshold is: ‒25°C. In this case, reliable disconnection can no
longer be guaranteed.
If the DC load-break switch is switched in spite of visible damage, again the reliable
disconnection function cannot be guaranteed.
High voltages are present in components that are not properly disconnected. Touching live
components can result in death or serious injury due to electric shock.
• Do not switch the DC load-break switch at temperatures below the specified threshold. The
threshold is: ‒25°C.
• Do not switch the DC load-break switch if it is visibly damaged.
Risk of burns due to hot components
Some components of the product can get very hot during operation. Touching these components
can cause burns.
• Observe the warnings on all components.
• During operation, do not touch any components marked with such warnings.
• Wear suitable personal protective equipment for all work on the product.
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.
