Safety
WARNING
Risk of electric shock
Installation and connection of a DEHNrecord SD may only be carried out by a qualified electrician
in accordance with the installation standards of the country.
Before mounting, check the DEHNrecord SD (DRC SD) and the accessories for external damage.
If any damage or other defect is detected, do not mount the DRC SD.
Loads exceeding the specified values may destroy the DRC SD and the electrical equipment connected to it.
Tampering with and modifying the DRC SD will void the warranty.
If the DRC SD is used together with a surge protective device (SPD) in environments with overvoltage category IV,
make sure that the SPD is functional before accessing the device.
If the SPD indicates a defect, the SPD must first be repaired before the DRC SD can be accessed.
The installation instructions for the SPD must be observed for this purpose.
2.1
