DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
 Disconnect all power from all equipment including connected devices prior to removing any
covers or doors, or installing or removing any accessories, hardware, cables, or wires except
under the specific conditions specified in the appropriate hardware guide for this equipment.
 Always use a properly rated voltage sensing device to confirm the power is off where and when
indicated.
 Replace and secure all covers, accessories, hardware, cables, and wires and confirm that a
proper ground connection exists before applying power to the unit.
 Use only the specified voltage when operating this equipment and any associated products.
Failure to follow these instructions will result in death or serious injury.
DANGER
POTENTIAL FOR EXPLOSION
Install and use this equipment in non-hazardous locations only.
Failure to follow these instructions will result in death or serious injury.
WARNING
LOSS OF CONTROL
 Consider the potential failure modes of control paths in the machine control system design,
such as:
 The possibility of backlight failure,
 Unanticipated link transmission delays or failures,
 The operator being unable to control the machine,
 The operator making errors in the control of the machine.
 Design outside the LT operations such as emergency stop, safety circuits, interlocks that
operate with opposing actions such as clockwise/counterclockwise rotation, and circuits that
prevent machine damage with positioning limits on top, bottom, and movement.
 For important operations handled by switches, design your system to use a separate hardware
device. This is to reduce the occurrence of incorrect outputs or malfunctions.
 Observe all accident prevention regulations and local safety guidelines. 1
 Test individually and thoroughly each implementation of the equipment for correct operation
before service.
Failure to follow these instructions can result in death, serious injury, or equipment
damage.
