currently we are using compressor Bock / EX-HGX4 x 4 pcs located at hazardous area.

We understood MP10 is safety protection for compressor, it is protected the compressor from winding overheat as well as discharge gas over heat.

We are monitoring and controlling the compressor by high pressure transmitter.
our main problem, do not have space in our PLC based control panel and

In this case, Is it necessary to install/connect MP10 with compressor?
Just for your info, we have many hazardous motors with PTC thermistor but we are not using it.

The MP10 is an integral part of the ATEX certification to prove protection for the temperature class rating (T3 max 200c). The thermistors are rated for 140c cut out temp.
As it is part of the certification process, use of the compressor without it will invalidate the EX certificate of the compressor.
So if you use it without the MP10 and a problem then happens due to over temperature of the compressor................... Bock won't be responsible
