N.W. For voltages different than 400 Volts there is no supplement except the versions at 230 Volt or lower voltages. For versions at 220, 230, 575 and 600 Volts with inverter on a main motore it’s obligatory to add the autotransformer in the price list.

N.W. The machine is produced in standard configuration Volt 400/ Hz 50 and must be fed by 3-phase + neutral + earth.
For feeding net at 400 Volt without neutral and voltages more than 400 Volt (even with neutral) it’s required the single-phase tranformer in the optional items of the price list.
For voltages 220/230 Volt (50/60 Hz) an additional cost is foreseen.

Machines can be equipped with sectionized pads in the Y, Z and Z super versions

Sectionized elastic pad (pitch 56) – Available for 1100 and 1350 versions equipped with electronic programmer FOX 500 KTR
Pitch 56: equipped with 20 sectors (version 1100) and 24 sectors (version 1350)
Sectors with adjustable single pressure, equipped with N° 2 contact inserts:
• half-rigid insert made by flexible steel+felt foil (density D=0,68) and graphite cloth (recommended for massive or veneered panels)
• soft insert made by thin flexible steel + rubber and felt foil (density D=0,68) and graphite cloth (recommended for veneered or painted panels)

Electronic sectionized pad (pitch 56 and pitch 30) – Available for versions 1100 and 1350 equipped with electronic programmer “FOX-500”
Pitch 56: equipped with 20 sectors (version 1100) and 24 sectors (version 1350)
