WARNING
If the machine is installed outdoors, it must be
properly sheltered under a roof.
Work environment conditions
- Relative humidity: 30-95% without condensa-
tion
- Temperature range: 0° - +55°
WARNING
Use of the machine in a potentially explosive
atmosphere is not permitted.
Fixing to the ground
It is not necessary to anchor the machine to
the ground, which must simply not be uneven
to permit the platform wheels to slide easily.
If the machine is to be fixed to the ground, use
M16 expansion plugs in the areas indicated
in Fig. 6.
ELECTRICAL HOOK-UP
The tyre changer must be powered with three-
phase current plus a neutral wire. The power
supply voltage must be specified in the pur-
chase order.

WARNING
All operations required for the electrical con-
nections of the equipment must be carried out
exclusively by a qualified electrician.
- The dimensions of the electric hook-up used
must be suitably sized in relation to:
• absorbed power specifications indicated on
the machine data plate;
• the distance between the machine and the
power supply hook-up point, so that voltage
drops under full load do not exceed 4% (10%
during start-up) compared with the rated
voltage specified on the data plate.
- The user must:
• fit a power plug that complies with the rel-
evant electrical safety standards;
• connect the machine to its own electrical
connection fitted with a suitable differential
circuit breaker;
• mount power line protection fuses, suitably
sized according to the specifications indi-
cated on the main wiring diagram contained
in this manual;
• install an efficient grounding circuit to protect
the workshop electrical system.
- To prevent unauthorised use of the machine,
always disconnect the power supply plug
when the machine is not used (switched off)
for extended periods of time.
-
If the machine is connected directly to the
power supply by means of the main electrical
board without a separate plug, install a key-
operated switch (or at least a switch that can be
locked) to restrict machine use to authorised
personnel only.
WARNING
For the correct functioning of the machine it is
vital to have a good ground connection. NEVER
connect the machine ground wire to the gas pipe,
water pipe, telephone wire or other makeshift
systems.
