Warning notes
To avoid injury to persons, damage to property or the environment, the following
warning notes should be observed!
Only authorized staff may open, interfere with or modify the unit!
• All activities (mounting, installation and service work, etc.) must be performed by
qualified staff
• Before performing any wiring changes in the connection area of the LEC1…, com-
pletely isolate the unit from the mains supply (all-polar disconnection)
• Ensure protection against electrical shock hazard by providing adequate protection
for the unit’s 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 lockout reset button only manually (applying a force of no more than 10 N),
without using any tools or pointed objects
• 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
• Do not press the lockout reset button on the unit or the remote lockout reset button
for more than 10 seconds since this damages the lockout relay in the unit
Mounting notes
• Ensure that the relevant national safety regulations are complied with
• Locate ignition electrode and ionization probe such that the ignition spark cannot
arc over to the ionization probe (risk of electrical overloads)
Installation notes
• Always run the high-voltage ignition cables separately while observing the greatest
possible distances to the unit and to other cables
• 4 extra terminals for the earth conductor, 4 extra terminals for the neutral conduc-
tor, and 4 auxiliary terminals
• In the event of loss of flame during operation, the control unit will initiate lockout
• Do not mix up live and neutral conductors
• Install switches, fuses, earthing, etc., in compliance with local regulations
• Observe the maximum permissible current load of the connecting terminals
