Omron NT-series Programmable Terminal V022-E3-1 - Manual (Page 12)




Safety Precautions (continued)

The cable’s tensile load is 30 N. Do not subject it to loads greater than this.
Otherwise a discontinuity may occur, causing operation to fail.

Do not install the NT600S at sites subject to the following conditions, or the
product may malfunction:
Severe temperature variations
Temperatures or humidities outside the ranges stated in the specifications
High humidity, condensation
Splashing chemical agents
Severe oil splashing
Corrosive or flammable gases
Strong vibrations or shocks
Direct exposure to wind and rain (outdoor sites)
Strong ultra-violet irradiation
 Take adequate measures to ensure shielding if the NT600S is used at a loca-
tion subject to any of the following conditions, or the product may malfunc-
tion:
Static electricity, or noise from other equipment
Strong electromagnetic fields
Nearby power cables
Potential exposure to radioactivity.

Carry out grounding correctly in order to prevent misoperation due to noise.

Confirm system safety before turning the power ON/OFF or resetting. Other-
wise the system may operate unpredictably.

Carefully check the operation of all screen data and host programs before
using them. If incorrect, the system may operate unpredictably. Otherwise
the system may operate unpredictably.

Turn off the NT600S power supply when connecting or disconnecting con-
nectors.

Check that the current capacity of the equipment to be supplied is within 150
mA before using the +5V output of pin No.6, or the product may malfunction.
The current capacity of +5 V output of NT600S is:
+5 V


5%, 150 mA max. with ST211(B)-V


, and
+5 V
5%, 100 mA max. with ST121(B)-V
.

Press touch switches with a force of no greater than 20 N. Applying higher
force may cause glass to break, cause injuries, and prevent operation.

Do not press touch switches carelessly while the backlight is off or while
nothing is displayed on the screen, or the system may operate unpredictably.
Only press touch switches after confirming system safety.

In a system where the user program operates according to the PC cycle
time, the system operation may not be constant because of cycle time fluc-
tuations. Consider this point when designing the system.
