Safety
DANGER High voltage. Risk of fatal injury due to electric shock!
Touching live parts poses an immediate risk of fatal injury. Damage to the insulation or
to individual components can lead to fatal injury.
Therefore:
▶
Permit only skilled electricians to work on electrical equipment.
▶
Before starting work, switch off the power supply and secure it against restoration.
▶
Before removing the casing or guard, check that the devices are deenergised.
▶
Keep moisture away from live components. Moisture can lead to short circuits.
WARNING Danger of burns due to hot surfaces!
Contact with hot components can cause serious burns.
▶
Suitable heat-resistant protective gear (such as face mask, safety gloves) must al­
ways be worn where any work is undertaken in the vicinity of hot components.
▶
Wherever possible, allow components to cool down to ambient temperature before
starting work.
Wherever possible, install or remove components only when the plant is shut down.
Before opening the duct access ports:
●
Make sure that no overpressure is present in the measurement duct.
●
Make sure that no toxic gases are present in the measurement duct.
If it is not possible to shut down the plant, and toxic gases, which may be at high tem­
perature or pressure, are present in the measurement duct:
