Technical description of the burner
4.13 RFGO-A22 control box
Warnings
All interventions (assembly and installation operations,
assistance, etc.) must be carried out by qualified personnel.
Before modifying the wiring in the control box connection
area, fully disconnect the system from the power supply
(omnipolar separation). Check the system is not powered
and cannot be accidentally reconnected. Failure to do this
will lead to the risk of electrocution.
Protection against electrocution from the control box and all
connected electric components is obtained with the correct
assembly.
Before any intervention (assembly and installation opera-
tions, assistance, etc.), ensure the wiring is in order and that
the parameters are correctly set, then make the safety
checks.
Falls and collisions can negatively affect the safety func-
tions.
In this case, the control box must not be operated, even if it
displays no evident damage.
For the safety and reliability of the control box, comply with the
following instructions:
–
avoid conditions that can favour the development of conden-
sate and humidity. Otherwise, before switching on again,
make sure that the entire control box is perfectly dry!
–
Static charges must be avoided since they can damage the
control box’s electronic components when touched.
