7. WIRING

WARNING
• Before starting installation work, turn off the power of this
unit and the connection destination. Do not turn on the
power again until installation is completed. Otherwise, it
will cause electric shock or fire.
• Use the accessories or specified power cable and
connection cables. Do not modify power cable and
connection cables other than those specified, do not use
extension cables, and do not use independent branch
wiring. The allowable current will be exceeded and cause
electric shock or fire.
• Install the connection cables securely to the terminal
board. Confirm that external force is not applied to the
cable. Use connection cables made of the specified
cable. If intermediate connection or insertion fixing are
imperfect, it will cause electric shock, fire, etc.
• When connecting the power cable and communication
cable, layout the wiring so that the cover of this unit is
securely fixed. If the cover is imperfectly fixed, it may
cause fire or overheating of the terminals.
• Perform ground work positively. Do not connect the
ground cable to a telephone ground cable, water pipe, or
conductor rod.
• Always fasten the outside covering of the connection
cable with the cable clamp. (If the insulator is chafed,
electric leakage may occur.)
• When performing cable wiring work, be sure that it does
not touch the user. Doing so will cause injury or electric
shock.
• If any cable is damaged, do not repair or modify it
yourself. Improper work will cause electric shock or fire.
