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.
