 Terminal X3-04: LME7 input current Max. 5 A Max. 5 A

Note
The input current for the LME7 at terminal X3-04 pin 5 also flows through safety loop
terminal X3-04 pin 1 / pin 2.
The power supply in the LME7 to the fan motor, ignition transformer, fuel valves, and
actuators is interrupted as soon as one of the components opens the safety loop
circuit.
