Caution:
• Use electrostatic discharge precautions (e.g., use of wrist straps)
during installation and wiring to prevent equipment damage.
• Avoid locations where severe shock or vibration, excessive
moisture or corrosive fumes are present. NEMA Type 4 housings
are intended for outdoor use primarily to provide a degree of
