[DESIGN PRECAUTIONS]
[Precautions for using products in a UL/cUL Class
, Division 2 environment]
●
Products
*1
with the Cl.
, DIV.2 mark on the rating plate are suitable for use in Class
, Division 2,
Groups A, B, C and D hazardous locations, or nonhazardous locations only.
This mark indicates that the product is certified for use in the Class
, Division 2 environment where
flammable gases, vapors, or liquids exist under abnormal conditions. When using the products in the
Class
, Division 2 environment, observe the following to reduce the risk of explosion.
-
This device is open-type and is to be installed in an enclosure suitable for the environment and
require a tool or key to open.
-
Warning - Explosion Hazard - Substitution of any component may impair suitability for Class
,
Division 2.
-
Warning - Explosion Hazard - Do not disconnect equipment while the circuit is live or unless the
area is known to be free of ignitable concentrations.
-
Do not open the cover of the CPU module and remove the battery unless the area is known to be
nonhazardous.
CAUTION
●
When an inductive load such as a lamp, heater, or solenoid valve is controlled, a large current
(approximately ten times greater than normal) may flow when the output is turned from off to on. Take
proper measures so that the flowing current does not exceed the value corresponding to the
maximum load specification of the resistance load.
●
After the CPU module is powered on or is reset, the time taken to enter the RUN status varies
depending on the system configuration, parameter settings, and/or program size.
Design circuits so that the entire system will always operate safely, regardless of this variation in time.
●
Simultaneously turn on and off the power supplies of the CPU module and extension modules.
●
If a long-time power failure or an abnormal voltage drop occurs, the PLC stops, and output is turned
off. When the power supply is restored, it will automatically restart (when the RUN/STOP/RESET
switch is on RUN side).
