2 | IMPORTANT SAFETY INSTRUCTIONS
DANGER
Risk of fatal injury due to electric shock!
Severe injuries or death may result from improper use of the interface connections and failure to observe pro-
tection class III.
1. The SELV circuits (SELV: safety extra low voltage) can only be connected to other SELV circuits with protec-
tion class III.
DANGER
Lethal voltages are still present in the connections and cables of the device even after the device
has been switched off and disconnected!
Severe injuries or death may occur if the cables and/or terminals/busbars in the device are touched.
1. The device is only permitted to be put into operation by a specialist.
2. Unauthorized persons must not be able to access the device.
DANGER
Dangerous voltage due to two operating voltages
Severe injuries or death may occur if the cables and/or terminals/busbars in the device are touched. The dis-
charge time of the capacitors is up to 5 minutes.
1. Only appropriately qualified electricians authorized by the mains supply network operator are permitted to
open and maintain the device.
2. Before opening the device: Disconnect the AC and DC side and wait at least 5 minutes.
DANGER
Risk of fatal injury due to electric shock!
Severe injuries or death will result if the live connections are touched. When there is solar radiation on the PV
generator, DC voltage will be present at the open ends of the DC cables.
1. Activate the connection power at the switchbox or string combiner with the DC isolator switch.
2. The DC connection is intended exclusively for PV generators. Other sources fall within the scope of im-
proper operation (e.g. batteries).
3. Only touch the PV generator cables on the insulation. Do not touch the exposed ends of the cables.
4. Avoid short circuits.
5. Do not connect any strings with a ground fault to the device.
DANGER
When deactivating the night shut-off ("Q on Demand" operation), a high DC voltage can con-
tinue to be present not only on the string combiner but also on the device, even though the string
combiner is switched off.
1. In case of maintenance, the device must also be deenergized on the AC-side.
2. We recommend attaching an appropriate hazard warning on the string combiner.
