page 15 of 64• Check the power source and the equipment’s rating plateto be sure that the power source and the equipmentmatch in voltage, phase, and frequency.• When working with residues, aggressive or condens-able media, install a gas washing bottle if necessary.The vacuum gauge is equipped with a short-circuit-proofwide-range power supply with an integrated overload pro-tection.Assemble and lock the suitable power plug (included inshipment) to the wall power supply prior to use.Avoid high heat supply (e.g., due to hot process gases).Connect the pressure transducer to the vacuum applica-tion.Position the pressure transducer and its vacuum line insuch a way that condensate cannot flow towards the pres-sure transducer.Allow the equipment to equilibrate to ambient temperatureif you bring it from cold environment into a room prior tooperation. Notice if there is water condensation on coldsurfaces.Comply with all applicable and relevant safety require-ments (regulations and guidelines). Implement the re-quired actions and adopt suitable safety measures.Ambient conditions➨ Do not reach for this product if it has fallen into liquid.There is a risk of deadly electrical shock.
