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.
