The use of the cable grommets and the pre-blanked holes can be
done in different manners; for example:
RS 25-35/M C05 single-phase
1
7-pole socket for single-phase power supply, thermostat/
pressure switch TL
2
6-pole socket for gas valves, gas pressure switch or de-
vice for checking the valve seal
3
4-pole socket for thermostat/pressure switch TR
4
5-pole socket, not used
5
2-pole socket for accessory min. gas pressure switch
6 - 6A Fittings for pipe unions
(Pierce, if it is necessary to use the pipe unions 6A)
RS 35/M C05 three-phase
1
7-pole socket for single-phase power supply, thermostat/
pressure switch TL
2
6-pole socket for gas valves, gas pressure switch or de-
vice for checking the valve seal
3
4-pole socket for thermostat/pressure switch TR
4
5-pole socket for three-phase power supply
5
2-pole socket for accessory min. gas pressure switch
6 - 6A Fittings for pipe unions
(Pierce, if it is necessary to use the pipe unions 6A)
The socket cover must only be removed when the
4-pole socket is in use.
When the 4-pole socket is not in use the cover
DANGER
must be in place.
The manufacturer furthermore declines any and
every responsibility for the failure to observe the
contents of this manual.

Calibration of the thermal relay (only for RS 35/M C05 three-phase)
The thermal relay is used to avoid damage to the motor owing to
a strong increase in absorption or the lack of a phase.
For the calibration, refer to the electrical wiring.
If the minimum value of the scale of the thermal relay is greater
than the rating absorption of the motor, protection is still ensured.
This arises when the power supply of the motor is 400 V.
To reset, in the case of an intervention of the thermal relay, press
the button 1)(Fig. 24).
Installation

After carrying out maintenance, cleaning or
checking operations, reassemble the cover and
all the safety and protection devices of the burner.
