Installation requirements
The Induction-Unit has to be build-in with the mounting frame in a flat horizontal area. Don’t
cover the air supply for the air circulation. The place must be allowing a weight at least 100
kg. To disconnect the Power, the user needs easy access to the power-connection.
Installation intructions for the build-in model
The following points must always be observed during installation:
-
Proof and take sure: the voltage of the main supply cable and the voltage of the
nameplate of the unit fit.
-
The induction unit must be with a potential compensation cable (6
mm² green / yellow - till 20kW, 16mm² green / yellow, -
over 20kW) to the terminal screw (M6x10 till 20 kW,
M8x10- over 20kW) and the on-site equipotential point of
the stove plant connected.
-
The induction unit in remote design (generator coil separately) must have a potential
compensation cable (6 mm² green / yellow -till 20kW, 16mm² green / yellow -over 20kW)
to the terminal screw (M6x10-till 20kW and M8x10-over 20kW) and the potential
equalization point of the generator compartment of oven plant are connected. Is the
generator compartment outside the cooking suite, also this must be connected to the on-
site equipotential point of the cooking suite.
The PE cable (6 mm² green/yellow) must be connected to the PE of the electrical
lead. The PE line has the same length as the coil extension.
-
All electric installations must fulfil the local building code regulations. All regulations issued
by the national electricity authorities must be observed.
-
The induction unit comes with a connection terminal or a main cable and can be connected
to a power point.
-
When using fault-current circuit breakers, they must be designed for a minimum fault
current of 30 mA.
-
Avoid blocking the air inlet and outlet zones with objects (textiles, walls, etc.).
-
Prevent hot ambient air from being drawn into the induction unit (for example, when
several units stand next to each other, behind each other, or when the unit is placed close
to deep fryers or ovens). In such cases, use a separate air duct.
-
The unit have an air filter. However, you must ensure that no fat surrounding air, which is
caused by other applications that could be sucked into the induction unit (near fryers,
griddles or deep fryers)
-
The air intake temperature has to be under +35°C.
-
The personnel operating the equipment must make sure that all installation, maintenance,
and inspection work is done by specially trained and certified personnel only.
-
The air must be channelled and get directly to the fans via the supplied filter. The
dimension of the air channel for each generator should be a least 200 cm².
-
Do not build thermal short circuit. The air exhaust may be sucked under no circumstances,
because the unit getting hotter.
-
The installation must be tested for practicality. For this the temperature has to be
determined. The point to measure is the heat sink base plate below the induction coil. The
temperature in permanent use within 2 hours and 20°C ambient temperature should not
be higher than 65°C.
-
All BI models (BI1EG- BI6EG) must be fastened (using the included mounting frame).
-
The main cable must always be shielded, clean contacts provided at both sides.
-
Select and set up the main isolator so, that the equipment is switched on and off no more
than 5 times a day.
-
For service and spare part exchange the unit have to be disconnected from the main
supply. Take sure the unit can`t be turned or switched on in any case.
Our induction units are equipped with cables that comply with the national regulations.
