Essential Safety Precautions
• To avoid the possibility of an electric shock, be sure to
connect the power cord to the PL before connecting it
to the main power supply.
• A fire or electrical shock may occur if voltages used with
the PL are beyond the specified range. Be sure to use
only the specified voltage.
• Before opening the PL unit’s rear maintenance cover, be
sure to turn the unit’s power OFF. This is because the
PL unit’s internal parts carry high voltages.
• To avoid fires or electrical hazards, do not modify the PL
in any way.
• Do not create touch panel switches that are used to either
control or to ensure the safety of equipment and person-
nel. Mechanical switches, such as an emergency stop
switch, a deadman (two-handed) start switch, etc., must be
installed and operated via a separate control system.
