Safety first!
The QC5200 is inherently safe, and in proper use few if any potential safety hazards exist. However, many
systems include motorized CNC stages that, as is the case with all motorized equipment, must be treated
with caution to avoid collision and pinch injuries. Also, an entire system often consists of electrical equip-
ment connected by many cables, which must be treated with care to avoid shock and tripping injuries.
WARNINGS - AXIS MOTION
Always stay clear of axis motion paths.
Disconnect axis motor power when motor activities are not required.
Be prepared to depress the emergency off mushroom switch or other similar device
quickly in the event of an emergency when motor axes are active.
WARNINGS - ELECTRICAL
Disconnect the system components from electrical sources before cleaning or
servicing.
Do not allow any power cord or signal cable to be located such that it can be walked
on or create a tripping hazard.
The system components are equipped with 3-wire power plugs that include a separate ground
connection, or are grounded through a separate wire. Always connect the power plug to a 3-wire
grounded outlet. The use of 2-wire power plug adapters or any other connection accessories that
remove the third grounded connection create a safety hazard and should not be permitted. If a
3-wire grounded outlet is not available, ask your electrician to provide one. Never disconnect any
separate ground wire.
Do not open the QC5200 enclosure. There are no user-serviceable components or assemblies
inside.
General safety precautions
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.
