5.4.3. Start-up of 380V three-phase work electrical pump (OPTIONAL)
Diesel-powered models can be equipped, on request, with a
380V three-phase electric pump.
To start the three-phase electrical pump:
▪ Insert the 380 V plug of the power cable into socket
( A ) on the chassis.
▪
Set the switches ( C ) shown in figure to ON position
▪ Set the angular red switch ( F) to ON position turning
it downwards or upwards. If the connection has been
successfully carried out it is possible to start the
electrical pump as indicated in next paragraphs. On
the contrary, in the event of a phase fault in the
electric power the audible alarm is automatically
enabled, and the electrical pump cannot be started.
In this case it is possible to compensate the power
phases by turning the angular red switch (
F ) on the
electric case by 90°.
▪

o
Select the platform control panel with the
locking key switch on the ground control
unit.
o

of turn clockwise.
o

NOTE The machine with 380V three-phase power can be operated only from the platform.
The operations carried out with 380V electrical pump are slightly slower than those with diesel engine.
NOTE: The electrical pump can be started only if the dead-man pedal is neither pressed nor enabled.
This means that the electrical pump can be started only if the platform green warning light ON is
flashing.
WARNING!! Always check the position of the power cord during the movements.
Disconnect all electric power supplies before opening the boxes.
