SAFETY
AND
INSTALLATION
1.1
SAFETY CONSIDERATION AND INSTALLATION CONSTRAINS
It is important to ensure that cable and connection are carried out by a qualified technician. Wrong
connections can cause damage to the device or generate dangerous situations for the user.
Dangerous voltages can be found inside the drive and on the external clamps, therefore
maximum attention should be paid during all phases of installation and/or maintenance so
that people are not placed in dangerous situations.
►
After switching off the drive, the internal components and the output connectors can still be powered for
several seconds. Before doing anything, check with a Voltmeter that there are no dangerous voltages
on the external clamps.
►
Between the control signals and the main power supply the insulation is guaranteed only for functional
purposes and not for user safety.
►
All the logic signals, besides the power lines, must be protected against the user direct contact.
►
During installation or normal operation, do not use damaged cables or spoiled ones.
►
Connect to the ground all the shields and the ground cables. Avoid untidy or twisted cables.
►
The converter must be installed in vertical position into the cabinet.
Ventilation conditions and surrounding
atmosphere must be settled in a way that the converter cannot work without nominal temperature
range (0÷40°C).
►
Relative air humidity must be kept below 90%, with no condensation
►
A 150mm clearance area must be considered over and under the driver, the drives and 50mm on the sides
in order to guarantee a high cooling efficiency to the fan.
►
The converter heat sink can reach high temperature during normal operations. Avoid direct contacts and
remove inflammable components into the closeness of the converter.
►
Before proceeding with the setup of the device it is necessary to check the ground connections, network
voltage and the correct connection (according to this manual) of the control signal connections
1.2
EMC ADVICES
All the cables connected to the Drive must be shielded and grounded.
►
An insulation transformer on the power line decoupling the drives from the grid is always a high efficiency
EMC barrier.
►
Where it is necessary to intersect the lay out between signal cables and power cables, it is better that the
intersections are made with cross angles of 90.
►
With cables length over 8/10m is not guarantee a full protection from EMC.
In case of this over length it is necessary to adapt all the measure to guarantee the complete elimination of EMC
and interference in the machine cables, e.g.:
- It is necessary separate the turret cables from other machines cables, using per
example separate canalisations
(with a distance of at least 30cm one from the other cable).
- The using of an external shielded wiring harness on the turret cables.
- External line filters are recommended (ie: Arctoronics F.LL.D3.016A.BN.R1 for 10A)
