To avoid injury to persons, damage to property or the environment, the following
warning notes must be observed!
Do not to 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
•
Check the connecting lines of the air pressure switch for short-circuits (connection
terminals 3, 6 and 11)

check to ensure that wiring is in an orderly state and make the safety checks as
described in «Commissioning notes»

When used in connection with actuators, there is no position feedback signal from
the actuator to the burner control
•
When used in connection with actuators, the requirements of applicable norms and
regulations must be observed
•
The running times of the actuators must match the burner control's program. An
additional safety check of the burner control together with the actuators is required
•
