•
Install a suitable disconnecting switch for each burner supply line.
•
The burner can be installed only in TN or TT systems. It cannot be
installed in isolated system of IT type.
•
The automatic reset function on the thermal device which protects
the fan motor cannot be enabled (by irreversibly removing the
relevant plastic label) for any reason.
•
As for the connection of cables to the terminals of the electrical
equipment, make sure that the earth conductor length is such as
to ensure that it is not subject in any way to accidental discon-
nection following any mechanical stress.
•
Provide for a suitable emergency stop circuit able to perform a
simultaneous stop in category 0 both on 220Vac single-phase line
and on 440Vac three-phase line. The disconnection of both power
supply lines ensures a safe transition in the shortest time possible.
•
The emergency stop must meet the requirements of the regula-
tions in force.
It is recommended that the emergency stop device is red and the
surface behind it is yellow.
The emergency action must be of the hold-to-run type and require
a manual operation to be restored.
When the emergency device is restored, the burner must not be
able to start autonomously, but a further "run" action by the opera-
tor must be required.
The emergency activation device must be clearly visible and easily
reachable and actionable in the immediate vicinity of the burner. It
must not be enclosed within protection systems or behind doors
that can be opened with keys or tools.
•
To ensure easy access by the operator for maintenance and
adjustment operations, provide for a suitable service plane in order
to ensure that the control panel is positioned between 0.4 ÷ 2.0
metres with respect to the service plane.
•
When installing the input power and control cables of the burner
electrical equipment, remove the protection plugs and provide for
suitable cable glands so that an "IP" protection degree equal to or
higher than that indicated on the burner nameplate can be
ensured.
