Glossary In these instructions the following technical terms with the specified meaning are used: Designation: Vacuum pump Compressor Machine Definition: Machine for generating a vacuum. Machine for generating a gauge pressure. Here: Vacuum pump or compressor. Unit for extracting, transporting and compressing gases and / or vapours, as well as for generating vacuum and gauge pressure. Here the drive is not considered part of the machine. Unit consisting of a machine and a drive motor. Two or more machines that are interconnected with couplings and mounted on a common base frame. Side of the machine on which the drive is connected. Pump-motor unit Machine set Driving side, D-end Non-driving side, N-end Inlet pressure Side of the machine on which no drive is connected. Pressure of the pumped gases / vapours at the inlet connection of the machine. Discharge pressure, Pressure of the pumped gases / vapours at the discharge connection of the macompression pressure chine. Test pressure Qualified personnel Pressure to which the machine is subjected when testing for leaks. Persons who, based on their training, experience and instruction, as well as their knowledge of the pertinent standards, regulations, accident protection regulations and operating conditions, are capable of carrying out certain tasks (e.g. start-up, operation, maintenance, repair) and can recognise and avoid possible dangers in the process. The required knowledge includes a knowledge of first aid and of the on-site emergency equipment. These persons must be authorised by the person responsible for system safety to perform the required tasks.
