8.1 Cautions
Before users undertake the maintenance and the inspection, they have to pay attention to the
following items.
The incorrect or careless operation will lead to damage to the staff and the
equipment.
z
To prevent a breakdown of an AH500 system or a fire accident, please make sure that the
ambient environment is not exposed to corrosive substances such as chloride gas and
sulfide gas, flammable substances such as oil mist and cutting powder, or dirt.
z
To prevent the connectors from oxidizing, or to prevent the staff from getting an electric
shock, please do not touch the connectors.
z
To prevent the staff from getting an electric shock, please turn off the power before pulling
the connectors or loosening the screws.
z
To prevent the cables from being damaged, or to prevent the connectors from being
loosened, please do not impose weight on the cable, or pull them violently.
z
Please make sure that the input voltage is within the rated range.
z
Please do not disassemble or alter the modules. Otherwise, the products will break down, a
fire accident will occur, or the staff will be injured.
z
To prevent a controlled element from malfunctioning, please make sure that the program
and the parameters are written into a new CPU module which replaces an old one before
restarting the AH500 system.
z
To prevent the improper operation which results in the incorrect output or the damage to the
equipment, please refer to the related manuals for more information about operating the
modules.
z
To prevent the damage to the modules, please touch metal which is grounded or wear an
antistatic wrist strap to release the static electricity from the body.
z
To prevent the noise from resulting in the breakdown of the system, please keep a proper
distance from the system when using a cell phone or a communication apparatus.
z
Please avoid installing an AH500 system under the sun or in a humid environment.
z
To prevent the temperature of an element from being high, please make sure that the
AH500 system keeps a proper distance from heat sources such as coils, heating
apparatuses, and resistors.
z
To protect an AH500 system, please install an emergency stop switch and an overcurrent
protection according to the actual needs.
z
Inserting and pulling a module several times may lead to the loose contact between the
module and the backplane.
z
To prevent an unexpected shock from resulting in the damage to an AH500 system and a
controlled element, please make sure that the modules are installed firmly.
