As supplied, the machine is set to run on the three phase voltage as indicated on the serial plate
and voltage label. Power connection to the machine is made to the main disconnect switch and the Ll,
L2, L3 and Ground terminals. The disconnect switch box is located on right side of the Operator Control
Panel.
In order to use the machine on a different supply voltage the following changes must be made:
1. Change the blade motor (or if equipped with a dual voltage motor, rewire it)
2. Change the hydraulic pump motor (or if equipped with dual voltage motor, rewire it)
3. Change the control transformer.
4. Change the blade and pump motor overloads, located adjacent to the contactor, to suit the
full load current of the new or rewired motor.
All other components are supplied from the control transformer and operate on 115V, single
phase. They do not need altering.
The machine is supplied for use on a 60HZ or 50Hz supply.
WHEN CHANGING THE SUPPLY VOLTAGE, CAREFULLY OBSERVE THE ABOVE STEPS. THESE
STEPS ARE ESSENTIAL TO AVOID SEVERE DAMAGE TO THE MOTORS AND CONTROLS.
At initial hook-up it is important to check that the phase order is correct. This is indicated by the
blade drive wheel revolving in a counter clockwise direction and the hydraulic pressure gauge
registering a pressure rise. On the following pages are the electrical schematics and physical wiring
diagrams along with a list and photos of electrical components.

TE: 1)The PLC is equipped with a lithium battery to keep the program stored while the power
is shut down. The battery will need to be replaced every 3 to 5 years, depending on usage. A visual
warning will be displayed on the interface when the battery drains to a certain level. Battaries can be
purchased through your Hyd-Mech Distibutor.

minutes after disconnect has been shut off. Cycling power sooner than 3 minutes will result in damage
to the Variable Frequency Drive.

3) All of the machines equipped with a Mitsubushi PLC have a snap on Ferrite core on the
interface cable. This is placed near the interface in order to reduce "noise"
