2. Hazard Warning Statements
The following are the hazard warning statements contained in this manual.
2.1 NOTICE Statement
(chapter 1, page 1-8)
NOTICE
Where for some reason the programmable controller has to be installed at a
location that has a possibility of being exposed to rain and water conditions, be
sure to mount it in a drip-proof enclosure. Disregarding this rule may result in
product failure.
(chapter 1, page 1-9)
NOTICE
Do not touch any of the modules in the programmable controller when they are in
an energized state. Touching any of the modules in an energized state may
lead to a discharge of static electricity from your body to the module, resulting in
malfunction or breakage of the module. If you have no choice but to touch such
a module, be sure to discharge the static electricity by touching the metal frame
of the cubicle and then touch the module. This is also true when you perform
any of the following actions on a module in its non-energized state: 1) setting a
switch on the module; 2) connecting or disconnecting the cable from the module;
or 3) inserting or removing the connector from the module.
(chapter 1, page 1-10)
NOTICE
The power supply module’s input voltage which is within its specification may be
close to the upper or lower limit of the specified range. In such a case, interpret
the input power as abnormal and ask personnel in charge of electric supply
facility management to check up the supply equipment.
