11.1.1 Installation Environment
This equipment has a high reliability regardless the installation environment. However, cares should be taken
for the following items in order to secure the reliability and stability.
1) Environment Condition
(1) Install in control panel with water-proof and vibration-proof.
(2) Free from impact or vibration.
(3) Do not expose directly to the sun.
(4) No condensing by sudden temperature change.
(5) Ambient temperature : 0 ~ 55
°
C.
(6) Incremental Humidity : 5 ~ 95% .
(7) Free from corrosive gas or inflammable gas
2) Installation Construction
(1) In case of processing of screw hole or wiring, do not enter the wiring fragments into PLC.
(2) Select the installation place good for operation.
(3) Do not install the equipment in the same panel with high voltage device.
(4) Keep more than 50mm from wiring duct or surrounding module.
(5) Grounding at the place where surrounding noise environment is good.
3) Heat Protection Design of Control Panel
(1) In case that PLC is installed in the airtight control panel, the heat protection design shall be carried out
considering radiation of other equipment as well as the heat of PLC itself. In case of air circulation using
the vent or general fan, PLC system may be influenced by the flow of dust or gas etc.
(2) It is recommended to install a filter or use the airtight heat exchanger.
