•
Always run high-voltage ignition cables separately while observing the greatest
possible distance to the unit and to other cables
•
Do not mix up live and neutral conductors
It is important to achieve practically disturbance- and loss-free signal transmission:
•
Never run the detector cable together with other cables
– Line capacitance reduces the magnitude of the flame signal
– Use a separate cable
•
Observe the maximum permissible detector cable lengths
•
The ionization probe is not protected against electric shock hazard. It is mains-
powered and must be protected against accidental contact
•
Locate the ignition electrode and the ionization probe such that the ignition spark
cannot arc over to the ionization probe (risk of electrical overloads)
