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 electrical layouts given in Appendix A.
declines all responsibility for modifications or connections different from those shown in the electrical lay-
outs.
Check that the electrical supply of the burner corresponds to that shown on the identification label and in this man-
ual. See Fig. 8.
Do not invert the neutral with the phase in the electrical supply line. Any inversion would cause a lockout due to firing
failure.
The burners RS 130/M have been type-approved for intermittent operation. This means they should compulsorily be
stopped at least once every 24 hours to enable the control box to perform checks of its own start-up efficiency. Nor-
mally, burner stopping is guaranteed by the boiler's thermostat/pressure switch.
If this is not the case, a time switch should be fitted in series to IN to provide for burner shutdown at least once every
24 hours. Refer to the electrical layouts given in Appendix A.
DANGER
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. Do not use the gas tubes as an earthing system
for electrical devices.
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 appliance.
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 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.
If the hood is still present, remove it and proceed with
the electrical wiring according to the layouts shown in
Appendix A.
Use flexible cables in compliance with the EN 60
335-1 standard.
All the cables to be connected to the burner must
be threaded through cable grommets.
See Fig. 20.
The use of the cable grommets can take various
forms. By way of example we indicate the following
mode:
1 - Three-phase power supply
2 - Single phase power supply
3 - Gas valves
4 - Gas pressure switch or the valve leak detection
device
5 - Consents/safety
6 - Available
