Essential Safety Precautions

PL-6700 Series User's Manual
Be sure to follow the instructions given below to ensure the safe
use of the PL.
To avoid a possiblity of electrical 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 result if voltages are used with the PL that are
beyond the specified range. Be sure to only use the specified voltage.
Before opening the PL's protective cover, be sure to turn the unit's power
OFF. This is because the PL's internal parts carry high voltages.
To avoid fires or electrical hazards, do not modify the product in any way.
Do not create touch panel switches that are used to either control or to ensure
the safety of equipment and personnel. 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.
If metal particles, water or other types of liquids contact any of the PL's inter-
nal parts, immediately turn the unit's power OFF, unplug the power cord,
and contact either your dealer or Digital Electronics Corporation.
Read and understand Chapter 4 "Installation and Wiring" thoroughly in order
to select an appropriate installation location for the PL.
Before either plugging in or unplugging a board or interface connector, be
sure to turn the PL's power OFF.
To prevent a possible explosion, do not install the PL in areas containing
flammable gases.
The PL is not appropriate for use with aircraft control devices, aerospace equip-
ment, central trunk data transmission (communication) devices, nuclear power
control devices, or medical life support equipment, due to these devices' inher-
ent requirements of extremely high levels of safety and reliability.
When using the PL with transportation vehicles (trains, cars and ships), di-
saster and crime prevention devices, various types of safety equipment, non-
life support related medical devices, etc. redundant and/or failsafe system
designs should be used to ensure the proper degree of reliability and safety.
