Danger: WORKING WITH ELECTRICAL SERVICES REQUIRED FOR A CNC ARE EXTREMELY HAZARDOUS. ALL POWER TO CNC MUST BE TURNED OFF LOCKOUT-TAGOUT AT THE SOURCE PRIOR TO CONNECTING THE LINE WIRES TO CNC. HOWEVER, IF THIS NOT THE CASE OR ARE NOT SURE HOW TO DO THIS, CHECK WITH APPROPIATE PERSONNEL OR OBTAIN THE NECESSARY HELP BEFORE CONTINUING. ALWAYS CHECK THE INCOMING LINES WITH AN AC VOLTAGE DETECTOR TO MAKE SURE POWER HAS BEEN DISCONNECTED.
Electrical power must be phased properly to avoid damage to your equipment. The Power Supply Assembly PC board incorporates a "Phase Detect" circuit with neon indicators. When the orange neon is lit (NE5), the phasing is incorrect. If the green neon is lit (NE6), the phasing is correct. If both neon indicators are lit, you have a loose wire; check the connections. Adjust phasing by setting the source power to off and then swapping L1 and L2 of the incoming power lines at the main circuit breaker.
Danger: ALL POWER TO CNC MUST BE TURNED OFF LOCKOUT-TAGOUT AT THE SOURCE PRIOR TO ADJUSTING PHASING. ALWAYS DOUBLE CHECK THE INCOMING LINES WITH AN AC VOLTAGE DETECTOR.
Turn off the power and set the main circuit breaker to OFF. Close the door, lock the latches, and turn the power back on.
Remove the key from the control cabinet and give it to the shop manager.
When the machine is properly placed and connected to both air and electrical power, it is ready for final installation (removing shipping blocks, leveling, spindle sweep, etc.) and software activation. The HFO service technician does this. Contact the local HFO to schedule the work.
