Attention!
Never open the device yourself, as this may compromise protection class IP 65.
Before connecting the device, be sure that the supply voltage agrees with the value printed
on the nameplate.
Connection of the device and maintenance work while under voltage must only be carried
out by a qualified electrician.
The power supply unit for the generation of the supply voltage for the VR 2300 and the re-
spective connector units must have a secure electrical insulation through double insulation
and safety transformers according to DIN VDE 0551 (IEC 742).
Be sure that the earthing conductor is connected correctly. Error-free operation is only guar-
anteed when the device is properly earthed.
If faults cannot be corrected, the device should be removed from operation and protected
against possible use.
