Warning notes 
To avoid injury to persons, damage to property or the environment, the following 
warning notes must be observed! 
 
Do not open, interfere with or modify the unit! 
 
  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 
  Ensure protection against electric shock hazard by providing adequate protection 
for the burner control’s connection terminals 
  Each time work has been carried out (mounting, installation, service work, etc.), 
check to ensure that wiring is in an orderly state and make the safety checks as 
described in «Commissioning notes» 
  Press the lockout reset button only manually (applying a force of no more than 10 
N), without using any tools or pointed objects 
  Do not press the lockout reset button on the unit or the remote reset button  (input 
21) for more than 10 seconds since this will damage the lockout relay in the unit 
  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 
  For safety reasons – self-test of the flame supervision circuit, etc. – at least one 
controlled shutdown must take place every 24 hours 
Mounting notes 
  Ensure that the relevant safety regulations are complied with 
  Connect the earthing lug inside the terminal base to burner ground using a screw 
with a lockwasher 
 
 
Note! 
In applications involving air heaters (WLE), or in the case of oil burners with a 
maximum throughput of >30 kW/h, removing wire link B is not permitted. 
Installation notes 
  Always run high-voltage ignition cables separately, with the greatest possible 
distance to the unit and to other cables 
  Live and neutral conductors must not be mixed up 
  Install switches, fuses, earthing, etc., in compliance with local regulations 
  Make certain that the maximum permissible current rating of the connection 
terminals will not be exceeded 
  The insulation on internal wiring which is subjected to the mains voltage must 
withstand the electrical stress occurring during correct use
