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 60
seconds.
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.
