Independently from the internal motor protection, fuses must be installed before the compressor. The selection of fuses has to be carried
out according to VDE 0635, DIN 57635, IEC 269-1or EN 60-269-1.

Diagnostics
CoreSense™ Diagnostics for all 4M* and 6M* Stream semi-hermetic compressors combines oil and motor protection into one module,
replacing OPS1/2 and the electronic module INT69TM. In addition, it provides advanced protection such as high discharge temperature,
locked rotor, single/missing phase, voltage imbalance and low voltage protection. The module is capable of communication via
Modbus® protocol. An external overload protection is not necessary.
