On request the balancing machine can be set up by the manufacturer to operate
with the power supply available in the place of installation. The set-up details for
each individual machine are given on the machine data plate and on a special label
attached to the power supply connection cable.
WARNING
All operations required for the electrical hook-up of the machine must be carried
out exclusively by a qualified electrician.
- The electrical supply must be suitably sized in relation to:
• absorbed power specifications indicated on the machine dataplate.
• the distance between the machine and the power supply hook-up point, so that
voltage drops under full load do not exceed 4% (10% in the case of start-up) below
the rated voltage specified on the dataplate.
- The user must equip the machine with the following:
• a dedicated power plug in compliance with the relevant electrical safety standards
• a suitable circuit-breaker (residual current set to 30 mA) on the mains connection
• power line fuses in accordance with specifications in the main wiring diagram of this
manual
• a suitable earthing system installed on the workshop mains line
- To prevent unauthorised use of the machine, always disconnect the mains 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 panel and without the use of a plug, install a key-operated switch or
suitable lock-out device to restrict machine use exclusively to qualified personnel.
WARNING
A good ground connection is essential for the correct functioning of the machine.
NEVER connect the machine ground wire to a gas pipe, water pipe, telephone cable
or other unsuitable objects.
