INSTALLATION GUIDELINES
In order to obtain a safe operation of the unit, assembly and start-up should be performed by skilled person-
nel only, according to the general regulations concerning safety conditions when working with high currents
or voltages.

Mechanical installation
Removal of the heat produced by the inverter is performed by ventilating with natural air flow, in low power models,
and by means of fan in all other models.
When assembling, leave a space of at least 40 mm (1.6"). from the sides and, on the heatsink side, 150 mm (6"). above
and below the inverter, soas to assure a free circulation of the cooling air. In case of stacking of more units, leave a vertical
space of at least 300 mm (12"). between them.
The site should assure the ventilation air is free from dust or corrosive gases, otherwise a regular cleaning of the
oling surfaces must be performed. Avoid, in any case, the condensation of the sprayed fluids. The ambient humidity
should never exceed 90%.
In working conditions, the temperature inside the cabinet should never exceed 40° C (104°F). If it should, it will be necessary
to perform a derating of the unit or a forced ventilation so as to avoid air stagnation.
Warning:
Electrical installation
• • • • •
The inverters are designed to operate in an industrial environment where high levels of electro-magnetic disturbance
(EMI) must be expected. Good installation practice usually ensure trouble-free operation, however it is suggested that a good
ground connection and RFI filters should be used. The RFI filters ensure a reduction of radiated or conducted interference when
the inverter is in a interference sensible environment. The instructions on the following page show how to perform the wiring
in order to be in compliance with the EMC norms.
In order to connect the inverter, just remove the cover which protects the power and control terminal boards; it can be
removed by acting on the clip placed on the front upper side of the cover itself.
The QUIXDrive series is foreseen for a single-phase or three-phases 220/240V power supply.
As for the power supply cables, we recommend to use two or three-wire shielded cables where the ground cable is external
and parallel to the shield; their dimensions must follow the values listed on page 10.
The same cable can be used for motor connection too. The cable length should never exceed 30 m (98"). If it should,
use additional inductances, series-connected with cables, to balance the parasitic capacities. In this case, a
of motor voltage can be noticed.
Warning
:
In case of shielded power supply cables, ground connect the shield on both sides.
The power cables must be kept separate from the signal cables. The standards require the use of separate raceways.
For control cables, use a shielded cable with a section of at least 0.5 mm
connected to the terminal 10 on drive side only.
For connection of reference signals or serial line, use twisted cables.
Connect spark quenching units in parallel to relay coils, solenoid valves, remote control switches located near the unit, as
suggested on the following table:
REMOTE CONTROL SWITCH
OR SOLENOID VALVE
220 V, 240 V
>30 A
220 V, 240 V
<30 A
Warning:
The failure protection circuit towards earth must ONLY protect the inverter against failures
towards earth, occurring on the motor cable or on the motor itself. It is NOT designed to protect
people who accidentally touch the motor or the corresponding supplying cable.
It is forbidden: to connect PFC devices to output terminals between inverter and motor;
Note:
When calculating the overall dimensions, also consider the space required for installation of anti-
noise filters.
The inverter power supply must be protected by means of fuses or automatic switches.
Make sure the cables are properly connected and, in particular, check that the ground connection
is correctly locked.

It is not advisable to connect remote control switches to output terminals between inverter and motor
if, while their functioning phase, both the motor and the inverter are running.
