 Only designated personnel are allowed to install wiring.
 Be sure to turn OFF the power prior to wiring to assure safety.
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 sports, 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 no ground connection is made to
a water pipe, gas pipe and lighting rod.
