Notes on safety for the electrical wiring
➤ The electrical wiring must be carried out with the electrical supply disconnected.
➤ Electrical wiring must be carried out by qualified personnel and in compliance with the regulations currently in
force in the country of destination. Refer to the wiring diagrams.
➤ declines all responsibility for modifications or connections different from those shown in the electrical
layouts.
➤ Do not invert the neutral with the phase in the electrical supply line. Any inversion would cause a lockout due to
firing failure.
➤ The RL 70-100-130 burners have been type-approved for intermittent operation. This means they should com-
pulsorily be stopped at least once every 24 hours to enable the control box to perform checks of its own start-up
efficiency. Normally the boiler's thermostat/pressure switch ensures the stopping of the burner.
If this is not the case, it is necessary to apply in series with IN a timer switch that turns off the burner at least once
every twenty-four hours.Refer to the wiring diagrams.
➤ The electrical safety of the device is obtained only when it is correctly connected to an efficient earthing system,
made according to current standards. It is necessary to check this fundamental safety requirement. In the event
of doubt, have the electrical system checked by qualified personnel.
➤ The electrical system must be suitable for the maximum input power of the device, as indicated on the label and
in the manual, checking in particular that the section of the cables is suitable for the input power of the device.
➤ For the main power supply of the device from the electricity mains:
- do not use adapters, multiple sockets or extensions;
- use an omnipolar switch with an opening of at least 3 mm (overvoltage category) between the contacts, as
indicated by the current safety standards.
➤ Do not touch the device with wet or damp body parts and/or in bare feet.
➤ Do not pull the electric cables.
