This product should be installed and serviced by a qualified technician, electrician, or electrical mainte-
nance person familiar with its operation and the hazards involved. Proper installation, which includes wiring,
mounting in proper enclosure, fusing or other over current 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 product is constructed of materials (plas-
tics, 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. It is the responsibility of the equipment manufacturer and individual installer to supply this
Safety Warning to the ultimate end user of this product. (SW effective 9/2000).
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 safety 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.
