2.1 Handling & hanging procedures
- The system is not equipped with specific lifting elements. Use
a fork lift truck paying attention during operations in order to
avoid the power source from tipping over.
Do not underestimate the weight of the equip-
ment: see technical specifications.
Do not move or position the suspended load
above persons or things.
Do not drop or apply undue pressure on the
equipment.
Do not lift the unit by the handle.
2.2 Positioning of the equipment
Keep to the following rules:
- Provide easy access to the equipment controls and connec-
tions.
- Do not position the equipment in very small spaces.
- Do not place the equipment on surfaces with inclination
exceeding 10° from to the horizontal plane.
- Position the equipment in a dry, clean and suitably ventilated
place.
- Protect the equipment against pouring rain and sun.
2.3 Connection
The power source is provided with a power supply cable for
connection to the mains.
The system can be powered by:
- three-phase 400V
- three-phase 230V
The mains voltage configuration can be changed only by quali-
fied personnel when the machine has been disconnected from
the mains, by removing the side cover and correctly positioning
the connections on the configuration array.
Voltage change configuration array
CAUTION: to prevent injury to persons or damage
to the equipment, the selected mains voltage and
fuses must be checked BEFORE connecting the
machine to the mains. Also check that the cable is
connected to a socket provided with earth contact.
Operation of the equipment is guaranteed for volt-
age tolerances up to +10-20% with respect to the
rated value (example: with Vnom 400V the work-
ing voltage is between 320V and 440V).
Before shipment, the power source is pre-set for
mains voltage at 400V.
The equipment can be powered by a engine driven
generator that guarantees a stable power supply volt-
age of ±15% with respect to the rated voltage value
declared by the manufacturer, in all possible operat-
ing conditions and at the maximum rated power.
Normally we recommend to use engine driven
generator with twice rated power of a single
phase power source or 1.5 times of a three-phase
power source.
Before connecting the power source you must be
sure the engine driven generator is an electronic
controlled one.
In order to protect users, the equipment must be
correctly earthed. The power supply voltage is pro-
vided with an earth lead (yellow - green), which
must be connected to a plug provided with earth
contact.
The electrical connections must be made by
skilled technicians with the specific professional
and technical qualifications and in compliance
with the regulations in force in the country where
the equipment is installed.
The power source supply cable is provided with a yellow/
green wire that must ALWAYS be earthed. This yellow/green
wire shall NEVER be used with other voltage conductors.
Verify the existence of the earthing in the used plant and the
good condition of the sockets.
Install only certified plugs according to the safety regula-
tions.
