All activities (mounting, installation and service work, etc.) must be performed by
qualified staff
• Before making any wiring changes in the connection area, completely isolate the
plant from mains supply (all-polar disconnection). Ensure that the plant cannot be
inadvertently switched on again and that it is indeed dead. If not observed, there is
a risk of electric shock hazard. If this is not observed, there is a risk of electric
shock
• Ensure protection against electric shock hazard by providing adequate protection
for the terminals. If this is not observed, there is a risk of electric shock
• Each time work has been carried out (mounting, installation, service work, etc.),
check to ensure that wiring is in an orderly state. If this is not observed, there is a
risk of electric shock
• Halogen lamps, welding equipment, special lamps or ignition sparks may produce
sufficient radiation for the detector’s UV cell to ignite. X-rays and gamma radiation
can also generate erroneous flame signals. If this is not observed, there is a risk
of loss of safety functions
• Fall or shock can adversely affect the safety functions. Such units must not be put
into operation, even if they do not exhibit any damage. If this is not observed,
there is a risk of loss of safety functions and a risk of electric shock
