• Execute 4 holes with 12 mm diameter on the floor
by the holes on the bottom floor;
• insert the small blocks (excluded from supply) into
the holes;
• fix the machine to the ground with 4 M12x120 mm
screws (excluded from supply) (
Fig. 9 ref. 1
) (or
with 4 12x80 mm stud bolts (excluded from supply)).
Tighten the screws with an approximate tightening
torque of 70 Nm.

10.0 ELECTRICAL CONNECTION
EVEN THE TINIEST PROCEDURE
OF AN ELECTRICAL NATURE
MUST BE CARRIED OUT BY PRO-
FESSIONALLY QUALIFIED STAFF.
BEFORE CONNECTING THE MA-
CHINE MAKE SURE THAT:
• THE MAIN POWER RATING COR
-
RESPONDS TO THE MACHINE
RATING AS SHOWN ON THE
MACHINE PLATE;
• ALL MAIN POWER COMPO
-
NENTS ARE IN GOOD CONDI-
TION;
• THE ELECTRICAL SYSTEM
IS PROPERLY GROUNDED
(GROUND WIRE MUST BE THE
SAME CROSS-SECTION AREA
AS THE LARGEST POWER SUP-
PLY CABLES OR GREATER);
• MAKE SURE THAT THE ELEC
-
TRICAL SYSTEM FEATURES A
CUTOUT WITH DIFFERENTIAL
PROTECTION SET AT 30 mA.
The machine is supplied with
1.5
m of free cable. A plug
corresponding to the following requirements must be
connected to the cable:
• Conformity to Norm
IEC 309
• 400 Volt – 16A
• 3P + Ground
• IP 44
Only for VARGNAV4113D - VARGNAV4113EID -
VARGNAV4113SAD - versions with inverter
• Conformity to Norm
IEC 309
•
230/400 Volt – 32A
•
3P + N + Ground
•
IP 44
On delivery, the machine is pre-set to operate at a
voltage of 400 V.
For any other type of power supply, ask the manufac-
turer at the time of purchase: a machine functioning
under the required voltage conditions will be prepared.
FIT A TYPE-APPROVED (AS RE-
PORTED BEFORE) PLUG TO THE
MACHINE CABLE (THE GROUND
WIRE IS YELLOW/GREEN AND
MUST NEVER BE CONNECTED TO
THE PHASE LEADS). MAKE SURE
THAT THE ELECTRICAL SYSTEM
IS COMPATIBLE WITH THE RATED
POWER ABSORPTION SPECIFIED
IN THIS MANUAL AND APT TO
ENSURE THAT VOLTAGE DROP
UNDER FULL LOAD WILL NOT
EXCEED 4% OF RATED VOLTAGE
(10% UPON START-UP).
IN CASE OF A CHANCE SUPPLY
FAILURE, AND/OR BEFORE ANY
POWER SUPPLY CONNECTIONS,
MOVE THE PEDALS TO THE NEU-
TRAL POSITION.
