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:
• POWER LINE SPECIFICATIONS
CORRESPOND TO MACHINE
REQUIREMENTS 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.
Connect the machine up to the mains by means of
the 3-pole plug provided (230 V 1-phase) through the
wall socket.
If the plug provided is not suitable for the wall socket,
fit a plug that complies with local and applicable regu-
lations. This operation must be performed by expert
and professional personnel.
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
ONE OF THE TWO PHASE LEADS).
MAKE SURE THAT THE ELECTRI-
CAL SYSTEM IS COMPATIBLE
WITH THE RATED POWER AB-
SORPTION 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).
FAILURE TO OBSERVE THE ABOVE
INSTRUCTIONS WILL IMMEDIATE-
LY INVALIDATE THE WARRANTY.
10.1 Electrical checks
BEFORE STARTING UP THE
WHEEL-BALANCER, BE SURE TO
BECOME FAMILIAR WITH THE LO-

CARRY OUT A DAILY CHECK OF
THE MAINTAINED ACTION CON-
TROLS CORRECT FUNCTIONING,
BEFORE STARTING MACHINE
OPERATION.
Once the plug/socket connection has been made, turn
on the machine using the main switch (
