Only designated personnel are allowed to install wiring.
Be sure to turn OFF the power prior to wiring the product.
Do not do any wiring when the system is energized.
The system wiring requires not only a thorough connection with the
designated cable but also securing to prevent loose connection. Poor
connection and securing may cause electric shock, heat spots, fire or
communication errors.
Be sure to supply the power to this system according to
specifications.
Supply pure AC power. Potential malfunction may
occur if a rectified AC with voltage rise (dv/dt) at
zero crossing exceeds 40V /200µ sec.
Always establish a connection to a ground for safety.
Be sure that the ground connection is not made to
a water pipe, gas pipe and lighting conductors.
