WIRING CONNECTIONS
After the machine is leveled 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:
1. Signs of damage that may have occurred during shipping to the electrical cables and the hydraulic hoses.
2. The hydraulic oil level is between the upper and lower lines on the level gauge.
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 L1, L2, L3 and Ground terminals in the main electrical box found beside the
conveyor on the drive side. For machines equipped with a variable frequency drive unit, an earth ground is also
recommended.
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: Running the hydraulics “backwards” can damage the hydraulic pump.
