The safe operaton of axs motors
The procedures contained in this guide might require some operation of axis motors under open-loop or
uncontrolled conditions. These operations must be conducted while following these instructions with
great care to avoid serious personal injury or equipment damage resulting from motor runaway.
WARNINGS
Always stay clear of axis motion paths.
Disconnect axis motor power when motor activities are not required.
Be prepared to depress an emergency off mushroom switch or other similar contact safety device
quickly to stop axis motion in the event of an emergency when axis motors are active.
Follow the instructions provided by this guide carefully. Do not hurry through procedures or skip
steps. If you are uncertain about any part of the CNC setup process, contact Metronics technical
support for assistance before continuing.
Other Safety Consderatons
General safety precautions must be followed when configuring, maintaining or operating the system.
Failure to observe these precautions could result in damage to the equipment, or injury to personnel.
It is understood that safety rules within individual companies vary. If a conflict exists between the material
contained in this guide and the rules of a company using this system, the more stringent rules should take
precedence.
Additional safety information is included throughout the remainder of this guide.
Electrical
Do not allow any power cord to be located such that it can be walked on or create a tripping hazard.
WARNINGS
Disconnect the QC-300 from power before cleaning.
The QC-300 is equipped with a 3-wire power plug that includes a separate ground
connection. Always connect the power plug to a 3-wire grounded outlet. The use of
accessories that remove the third grounded connection such as a 2-wire power plug adapter create
a safety hazard and should not be permitted. If a 3-wire grounded outlet is not available, ask your
electrician to provide one.
