This product should be installed and serviced by a qualified technician, electrician or electrical
maintenance personnel familiar with its operations and the hazards involved. Proper installa-
tion (see instruction information which accompanies product), 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
when working with control under power. This product is constructed of materials (plastics,
