3 For Your Safety
3.3 Installation Notes
• Lay high-voltage ignition cable always separately and in safe distance from device and
other cables.
• Only trained, qualified personnel may open the BurnerTronic’s cover.
• Observe local and national regulations when wiring the electric cables inside the burner.
• Tighten the screw terminals of the BT300 using a tightening torque of > 0.5 Nm.
• Supply the feed cable with L, N and PE only. The N neutral conductor must not have po-
tential difference to the PE protective conductor.
• The pre-fuse for the BT300 should be max.10 A slow-blow.
• Phase, neutral and central point conductors must not be interchanged (this would lead to
dangerous malfunctioning, loss of protection against contact, etc.).
• The strain relief for the connected cables must comply with standards (e.g. DIN EN 60730
and DIN EN 60335).
• Make sure that no spliced strands can come into contact with any of the adjacent connec-
tions. Use appropriate end sleeves.
• The burner manufacturer is obligated to supply unused connections on the BT300 with
dummy plugs.
• To replace or disconnect the plug connectors, all poles of the plant must be disconnected
from the mains.
• Make a form-fit connection between the actuators and actuating elements for fuel and
combustion air, as well as a form-fit connection for any additional actuator element.
• Optional components with safety extra low voltage (SELV) must be safely separated from
the mains. Otherwise this can cause an electrical shock or damage the device due to a
short-circuit.
• You may connect only passive devices or devices without feedback effects at the 230V
outputs of the BT300 (like relays without additional voltage connection). In case of error it
must be guaranteed that BT300 is not fed with 230 V by this terminals.
• To avoid disruption of the UI300’s display during ignition, a damping resistor of 1 ... 5 k

must be installed in the high-voltage ignition line.
• To avoid disturbance on the Bus, the termination must be active on the first and the last
device connected to the bus must be terminated.
3.4 Electrical Connection Flame Sensor
Interruptions and losses in signal transmission need to be minimised:
•
Do not wire the sensor cable with other cables.
Flame signal is reduced through line capacities.

Use a separate 7-pole cable.
• Consider the permitted length of sensor cables.
• The ionisation flame sensor supplied from the mains is not protected against contact. Pro-
tection against accidental contact is therefore obligatory.
• Ground the burner according to instructions – grounding the boiler itself is not sufficient!
• Position ignition electrode and ionisation flame sensor where spark cannot hit ionisation
flame sensor (risk of electrical overloading).
