WIRING CONNECTIONS
After the machine is levelled and anchored, the necessary power hook-up needs to be performed. In order to
provide safe operation as well as to prevent potential damage to the machine, only qualified personnel should
make the connections.
BEFORE START-UP THE FOLLOWING TWO POINTS SHOULD BE CHECKED:
-Signs of damage that may have occurred during shipping to the electrical cables and the
hydraulic hoses.
-The hydraulic oil level is between the upper and lower lines on the level gauge on the front of the control
panel base.
As supplied, the machine is set to run on three phase voltage as indicated on the serial plate and voltage
label. Power connection to the machine is made to FU2 fuses and ground connections inside the electrical panel
as shown below.
During the initial hook-up it is very important to check that the phase order is correct. This is indicated by the
hydraulic pressure gauge registering a pressure rise and the blade running in a counter clockwise direction. If
the hydraulics do not register an immediate pressure rise, shut the hydraulics off and change the phase order.
ATTENTION: 1) Running the hydraulics "backwards" can damage the hydraulic pump.
2) After checking the hydraulic pressure and BEFORE INSTALLING the drive chain
between the infeed conveyors, check that the conveyors are running in the correct
direction. If they are not, change any two phases at the MOTOR JONCTION BOX for
each motor as required.
Power connections should be made by qualified personnel only
