3.3 ELECTRICAL CONNECTIONS TO THE BURNER TERMINAL STRIP
IN Manual stop switch
MB Burner terminal strip
H Lock-out signal
NOTE
Wire section: min. 1 sq. mm.
(Unless required otherwise by local standards and legis-
lation).
For supply at 230V make the triangle connection on
the pre-heater and on the motor (the original connec-
tion is "star" for 400V).
TWO STAGE OPERATION
This is achieved by the remote control device connected to
terminals 5-6 (removing the jumper), that controls 2
valve.
FASTENING OF THE ELECTRICAL WIRES
All the wires, to be connected to the burner terminal strip (16, fig. 1) shall pass through the cable entries
(17, fig. 1), see the figure below.
D2635
Further prospective signals or controls can be connected to the burner terminal strip by presheared disk inserting
a common cable gland for the passage and the clamping of the leads. To ensure the IP 40 degree of protection
in compliance with EN 60529 close the passage holes of the cables and any unused entry leads with appropriate
disks.
NOTES
- Make a safe earth connection.
- Verify the burner stop by opening the boiler thermostat and the burner lock-out by darkening the photocell.
