5.4.3 Starting the 380V three-phase electric pump (OPTIONAL)
Diesel-powered models can be equipped, on request, with a
380V three-phase electric pump.
To start the three-phase electrical pump:
1)
Insert the 380 V plug of the power cable into socket ( A )
on the chassis.
2) Set the switches ( C ) shown in figure to ON position.
3)
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°.
4) To start the electric pump with the platform controls:
Select the platform control panel with the locking key
switch on the ground control unit.
Unlock the push-button turning by a ¼ of turn
clockwise.
Set the power selector to "Electric" position.
Select the 380V power with selector.
Press the button ( H ) When on, the green warning
light indicates that the three-phase electric pump is
turned on.
Wait 5 seconds before moving the machine.
5) To stop the electric pump press button (
H
) again.

NOTE The platform 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 electric pump can be started only if the dead-man pedal and button are 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.
