Ñ-2. CONNECTING TO THE ELECTRICAL NETWORK
After connecting the burner to the boiler, the technician should connect the burner
to the electrical network as shown on the enclosed connection scheme.
ATTENTION! The connection must be done by a qualified electrical
technician and there must be paid high attention to the safety grounding
of the device. The connecting is shown in the present manual and also with
special stickers to the main cable.
Connecting:
A four-wired cable which is connected to the boiler, goes out of the burner. The
meanings of the conductors are as they follow:
· black – phase (220V, 50Hz) – the black conductor connects to a terminal
from the boiler, which when the main switch is on always has 220V
phase (if the emergency thermostat is not on). This is the power supply
of the burner.
· Brown - (220V, 50Hz) from thermostat (start burner) – the brown
conductor connects to a terminal, connected with the boiler’s thermostat.
It gives a phase (with the same polarity as the power supply ) for starting
the burner, i.e. when a voltage shows on this conductor, the burner
perceives it as a start-burning signal. When the set temperature is
reached, the thermostat turns off, the pressure goes off and the burner
stops running.
· Blue - N – neutral – the blue conductor must be connected to the
neutral conductor.
· yellow/green - PE – protective earth – the yellow-green conductor
must be connected to the grounding.
