3 INSTALLATION
The system must be installed by qualified personnel. All
the connections must comply with applicable standards
and be made in full compliance with safety regulations
(see CEI 26-23 / IEC-TS 62081).
Make sure the supply cable is disconnected during all the
installation phases.
Carefully keep to the earth connection diagram shown on
Appendix.
3.1 UNPACKING AND ASSEMBLY
To move the power source, use a fork-lift truck.
To remove the wooden platform forming part of the pack-
aging:
• loosen the 4 wooden platform retention screws
• lift the power source using a fork-lift truck and posi-
tion the forks, bearing in mind the position of its centre of
gravity (see Fig. 2).
3.2 CONNECTING THE POWER SOURCE.
All the connections must be made by qualified personnel.
Plasma Prof 166 HQC power source
• The power source is supplied with power voltage 400V
three-phase. For different power voltages: remove the left
side of the power source (see spare parts list), remove the
cover of the terminal boards and proceed as indicated in
figure 10a.
In case of 230V three-phase power supply, put in short cir-
cuit also the first terminal on the bottom on the left with the
last one on the bottom on the right (see fig. 10a, 230V box)
using the cable supplied (fixed, by means of a fastener, on
the terminal board cables).
