D.1 Cautions
Observe the following precautions before performing maintenance and inspection. Incorrect or careless operation
will lead to injury or equipment damage.

To prevent a breakdown of a DVP-ES3 Series system or a fire, ensure that the ambient environment
does not contain corrosive substances such as chloride gas, sulfide gas or flammable substances such
as oil mist, cutting powder, or dirt.

To prevent the connectors from oxidizing and to prevent electric shock, do not touch the connectors.

To prevent electric shock, turn off the power before pulling the connectors or loosening the screws.

To prevent cable damage, and to prevent the connectors from being loosened, do not put weight on the
cables or pull on them.

Ensure that the input voltage is within the rated range.

To prevent product breakdown, fire, or injury, do not disassemble or alter the modules.

To prevent a controlled element from malfunctioning, ensure that the program and parameters are written
into a new CPU module before restarting the DVP-ES3 Series system.

To prevent incorrect output or equipment damage, refer to the related manuals for more information
about operating the modules.

To prevent damage to the modules, touch grounded metal or wear an antistatic wrist strap to release
static electricity from your body before working on a module.

To prevent noise from causing system breakdown, keep a proper distance from the system when using a
cell phone or communication device.

Do not install a DVP-ES3 Series system in direct sun or in a humid environment.

To prevent the temperature of an element from being too high, maintain a proper distance between the
DVP-ES3 Series system and heat sources such as coils, heating devices, and resistors.

To protect a DVP-ES3 Series system, install an emergency stop switch and an overcurrent protection
device.

Inserting and pulling a module several times can loosen the contact between the module and the
backplane.

To prevent an unexpected shock from resulting in damage to the DVP-ES3 Series system and a
controlled element, ensure that the modules are correctly and firmly installed.
