SMA String-Monitors Ethernet overvoltage protection set - Manual (Page 21)

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).
Risk of property damage through use of defective overvoltage protection unit for
communication
A defective overvoltage protection unit no longer affords protection from surge voltage. In case of
overvoltage, the devices connected via the data cables may be damaged.
• Replace any defective overvoltage protection unit.
A defect may have occurred if the communication link is interrupted.
