Electrical Safety
Caution:
When you do maintenance or repair on CNC machines and their components, you must always follow
basic safety precautions. This decreases the risk of injury and mechanical damage.
• Set the main circuit breaker to the
[OFF]
position.
Danger:
Before beginning any work inside the control cabinet the High Voltage indicator light on the 320V Power
Supply / Vector Drive must have been off for at least 5 minutes.
Some service procedures can be dangerous or life-threatening. DO NOT attempt a procedure that you do not fully
understand. If you have any doubts about doing a procedure contact your Haas Factory Outlet (HFO) and schedule a
service visit.
The Haas Vector drive is the source of power for
the spindle motor and the servo amplifiers. There
are three sizes of Haas Vector drives: 20HP [1],
