HP441S.XX - HP441S.XXFI
HP441SQ.XX - HP441SQ.XXFI
On delivery, the machines are preset to operate at
a three-phase voltage of 230/400V - 50-60 Hz (for
HP441S versions) or with a three-phase voltage of
230/400V - 50 Hz (for HP441SQ versions).
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 PLUG
TO THE MACHINE CABLE (THE
GROUND WIRE IS YELLOW/GREEN
AND MUST NEVER BE CONNECTED
TO ONE OF THE 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).
10.6 Check of motor rotation direction
Once all power connections have been made, make
sure that the mandrel is rotating in the right direction
(pedal lowered, clockwise rotation). If the direction of
rotation is wrong, swap two phase wires in the plug.
FAILURE TO OBSERVE THE ABOVE
INSTRUCTIONS WILL IMMEDIATE-
LY INVALIDATE THE WARRANTY.
