vant standards.
Explosion-protected versions of this device may only be operated by person-
nel who have undergone special training or instructions, or who are auth-

Any hazards which could be caused by the process medium, the operating
pressure, the signal pressure and moving parts of the control valve, must be
prevented by means of appropriate measures.
