Grounding
The design of the earthing system for the overall plant instrumentation consists of two different and independent systems, designed as follows:
Protection earth (PE), which connects to the Electrical Common Ground System (cabinets, frames, etc.);
Functional earthing (FE), designed for earthing of all equipment with very low voltage, for instance for microprocessors protection, etc.
To the FE are connected:

Control system ground;
Instrument earth (field cable shields);
Intrinsically safe instrument earth (field cable shields).

Интересует фраза:

To the FE are connected:

Control system ground;

К функциональному заземлению подключают (или функц. заземление обеспечивают для?)

(второй раз не нужно писать заземление - ground?) - систему управления;
