IMPORTANT SAFETY INSTRUCTIONS

Keep the manual for future reference.
This section contains safety information that must be observed at all times when working.
The product has been designed and tested in accordance with international safety requirements. As
with all electrical or electronical devices, there are residual risks despite careful construction. To
prevent personal injury and property damage and to ensure long-term operation of the product,
read this section carefully and observe all safety information at all times.

DANGER

Danger to life due to electric shock when live components or DC cables are
touched

When exposed to light, the PV modules generate high DC voltage which is present in the DC
cables. Touching live DC cables results in death or lethal injuries due to electric shock.

• Do not touch non-insulated parts or cables.
• Disconnect the product from voltage sources and make sure it cannot be reconnected

before working on the device.

• Do not disconnect the DC connectors under load.
• Wear suitable personal protective equipment for all work on the product.

DANGER

Danger to life due to electric shock when live components are touched on
opening the product

High voltages are present in the live parts and cables inside the product during operation.
Touching live parts and cables results in death or lethal injuries due to electric shock.

• Do not open the product.

DANGER

Danger to life due to electric shock when touching live system components in
case of a ground fault

If a ground fault occurs, parts of the system may still be live. Touching live parts and cables
results in death or lethal injuries due to electric shock.

• Disconnect the product from voltage sources and make sure it cannot be reconnected

before working on the device.

• Touch the cables of the PV array on the insulation only.
• Do not touch any parts of the substructure or frame of the PV array.
• Do not connect PV strings with ground faults to the inverter.
• Ensure that no voltage is present and wait five minutes before touching any parts of the PV

system or the product.
