Vestil HDC-900, Owner'S Manual

Electrical System Specifications: 

This hydraulic drum crusher, model HDC-900 or HDC-905, was tested at the factory at the 
voltage specified at the time of order.  For applications that require voltages that differ from 
original specifications, the motor and control transformer must be rewired for the appropriate 
voltage. Failure to do so automatically voids the “Limited Warranty” (see p. 12A & 12B) and 
might significantly damage the electrical system.  

Motor wiring: 

The table below indicates how to wire 3-phase motors of specified voltages.

Transformer:

If the supply voltage to the motor is changed, the primary wires of the transformer must also be changed 
(refer to “Electrical system diagram” on p. 8; also refer to the label on the transformer to properly connect 
to the supply voltage).
