SAFETY WARNING! Please read carefully before proceeding.
This product should be installed and serviced by a qualified technician, electrician, or electrical maintenance person familiar with its operation and the
hazards involved. Proper installation, which includes wiring, mounting in proper enclosure, fusing or other overcurrent protection, and grounding can
reduce the chance of electrical shocks, fires, or explosion in this product or products used with this product, such as electric motors, switches, coils,
solenoids, and/or relays. Eye protection must be worn and insulated adjustment tools must be used when working with control under power. This prod-
uct is constructed of materials (plastics, metals, carbon, silicon, etc.) which may be a potential hazard. Proper shielding, grounding and filtering of this
product can reduce the emission of radio frequency interference (RFI) which may adversely affect sensitive electronic equipment. If further information is
required on this product, contact the Sales Department.
This control contains electronic Start/Stop circuits that can be used to start and stop the control. However, these circuits are never to be used as safe-
ty disconnects since they are not fail-safe. Use only the AC line for this purpose.
Be sure to follow all instructions carefully. Fire and/or electrocution can result due to improper use of this product.
It is the responsibility of the equipment manufacturer and individual installer to supply this Safety Warning to the ultimate end user of this product. (1/2001)
