Connection description
ATTENTION!
Never open the device yourself, as this may compromise degree of protection IP 65.
Before connecting the device, be sure that the supply voltage agrees with the value printed
on the name plate.
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 BPS 37 and the
respective connection units must have a secure electrical insulation through double
insulation and safety transformers according to DIN VDE 0551 (IEC 742).
Be sure that the protective conductor is connected correctly. Fault-free operation is only
guaranteed when the device is properly earthed.
If faults cannot be cleared, the device should be switched off and protected against
accidental use.
