outlined in this installation manual.
Installation work must be performed in accordance with
national wiring standards by authorized personnel only.
Before installation, be sure that all sources of power have
been shut off. There is a danger of electric shock.
Never touch electrical components immediately after the
power supply has been turned off. Electrical shock may
occur. After turning off the power, always wait 5 minutes or
more before touching electrical components.
For installation purposes, be sure to use the parts supplied
by the manufacturer or other prescribed parts. The use of
non-prescribed parts can cause serious accidents such as
