Industrial System and Method of Controlling Industrial System

A method of controlling an industrial system, comprising:

• providing an industrial system comprising:
• an industrial actuator including a primary compartment containing at least one primary electric device and a secondary compartment containing at least one secondary electric device;
• a pressure system configured to generate an overpressure in the primary compartment with respect to an exterior region outside of the industrial actuator, and to generate an overpressure in the secondary compartment with respect to the exterior region;
• a power line adapted for supplying electric power to each primary electric device and each secondary electric device;
• and
• a primary switch disposed along the power line and arranged to selectively connect and disconnect power supplied to each primary electric device and each secondary electric device;
• and
• a secondary switch disposed along the power line and arranged to selectively connect and disconnect power supplied to each secondary electric device, the secondary switch being positioned inside the primary compartment;
• controlling the primary switch to adopt a disconnected state;
• controlling the secondary switch to adopt a disconnected state;
• generating, by the pressure system and while the primary switch and the secondary switch are in the respective disconnected state, an overpressure in the primary compartment with respect to the exterior region;
• controlling, after generating the overpressure in the primary compartment, the primary switch to adopt a connected state to provide power to each primary electric device;
• generating, by the pressure system and while the primary switch is in the connected state, an overpressure in the secondary compartment with respect to the exterior region;
• and
• controlling, after generating the overpressure in the secondary compartment, the secondary switch to adopt a connected state to provide power to each secondary electric device.
