3.3 ELECTRICAL CONNECTIONS TO THE TERMINAL STRIP
NOTE
Wire cross sections: min. 1 sq. mm.
(Unless required otherwise by local standards
and legislation).
TWO STAGE OPERATION
This is achieved by the remote control device
connected to terminals 5-6 (removing the jump-
er), that controls the second valve.
FASTENING OF THE ELECTRICAL WIRES
All the wires, which have to be connected to the burner terminal strip (16, fig. 1) shall pass through the cable
glands (17, fig. 1), see the figure below.
D2635
Further prospective signals or controls can be connected to the burner terminal strip pushing out the pre-sheared
disc from the holes and 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 un-
used cable entries with appropriate discs.
NOTES
- Make a safe earth connection.
- Verify the burner stop by opening the boiler thermostat and the burner lock-out by darkening the photocell.
