Installation, operation, and maintenance must be performed by qualified personnel, in indoor locations, following all applicable standards and regulations, and never exceeding the equipment’s rated parameters.
For air transport the gas pressure is reduced, and before on‑site assembly the gas chamber must be re‑pressurised to the specified filling pressure.
Standard strength 8.8 grade bolts should be tightened according to the torque values listed in Table 2.1.2.1.
The technical parameters are listed on the nameplate inside the low‑voltage compartment and summarized in the “Technical Parameters” section of the guide.
