MOUNTING THE TOP UNITS ON A BASE OR AN EXTENDING SUPPORT

All Top units are supplied with height-adjustable feet (P):
- When the unit is to be placed free on a table or a surface,
tighten or loosen the feet (P) as shown in the illustration
till it is perfectly steady, then tighten the locknut (D) so
that the foot is blocked. To prevent slipping, insert the
rubber plugs (M) into the feet's lower holes.
- When the unit is to be fixed to a base or an extending
support, adjust the feet (P) till it is perfectly steady,
then tighten the locknut (D) so that the foot is blocked.
Subsequently fasten from beneath by way of M5 screws
(T) and respective washers, screwing them into the feet
as shown in the illustration
3.
Electrical connection should be performed in compliance with the IEC regulations, only by authorised and competent personnel.
In the first instance, examine the data shown on the technical data table of this manual, on the label and on the electrical
diagram. The envisaged connection is of the fixed type.
IMPORTANT: Ahead of each unit it is necessary to install an omnipolar main breaker, having a spacing among contacts of
at least 3mm; example:
- manual breaker of appropriate capacity, complete with fuse valves
- automatic breaker with respective magnetothermal relays.

EARTHING

It is essential to earth the unit.
To this purpose, it is necessary to connect to an efficient earthing system the terminals marked with the symbols (
on the line-receiving terminal box. The earthing system should comply with the law in force.
SPECIFIC WARNINGS
The electrical safety of this unit is assured only when it is correctly connected to an efficient earthing system as stated
in the electrical safety regulations in force; the Manufacturer declines any responsibility for the non-compliance with
these safety regulations.
It is necessary to verify this fundamental safety requisite and, in case of doubt, ask for an accurate testing of the system by
professionally qualified personnel.
The Manufacturer cannot be deemed responsible for any damages caused by the lack of unit earthing.
ATTENTION: NEVER INTERRUPT THE EARTH WIRE (Yellow-Green).
3.2

EQUIPOTENTIAL

The unit should be included within an equipotential system whose efficiency must be tested according to the law in force.
The screw marked with the label "Equipotential" is located near the terminal box on the base for models with oven, and at
the back for the remaining models.
3.3

POWER SUPPLY CABLE

The unit is supplied fitted for the following voltages: 3N AC 380...415V; 3 AC 220...240V; 1N AC 220...240V 50/60 Hz.
The flexible cable for power supply connection should not have characteristics lower than the rubber insulation type
H07RN-F. The cable should be inserted through the cable clamp and firmly fastened. Furthermore, the supply voltage with
the unit functioning should not go outside the value of the nominal tension ±10%.
