Safety Precautions - Mitsubishi Electric MES3-255C-DM-EN User Manual

1. Safety Precautions

 Precautions concerning the operating environment and usage conditions
Do not use the product in the places specified below. Failure to observe this may result in malfunction or reduced life of
the product.
 Ambient temperature exceeds 0 to +55 ºC.
(Température ambiante excède 0º à +55 ºC.)
 Daily average ambient temperature exceeds 35 ºC.
(Température ambiante quotidienne et moyenne excède 35 ºC.)
 Relative humidity exceeds 5 to 95% or condensation is
observed.
(Humidité relative excède 5% à 95% ou condensation est
observée.)
 Altitude exceeds 2000 m.
(Altitude excède 2000 m.)
 Dust, corrosive gas, saline and oil smoke exist.
(Poussière, gaz corrosif, salin et huile fumée existe.)
 Precautions concerning the installation
Read this instruction manual before installation.
 The product shall be installed and wired by technicians specializing in electric work.
 Always handle the end face of metal parts with care. The sharp part may cause injuries.
 During threading or wiring work, take precaution so that any metal chip or a part of wire cut does not enter the
product.
 Make sure to use the connection diagram for correct wire connection. Incorrect wiring may cause the device
malfunction, fire or electric shock.
 Never work with live wires. Otherwise, it may lead to electric shock, fire or device problems.
 Use electric wires of appropriate size. If an inappropriate size electric wire is used, it may cause fire due to
generated heat.
 Use solderless terminals which fit the wire. If an inappropriate solderless terminal is used, wire breakage or contact
failure may occur, resulting in the device malfunction, failure, burnout, or fire.
 To comply with the UL/c-UL standard, use wires whose temperature rating is 60 ºC/75 ºC for copper conductors.
(Pour UL/c-UL standard, utilisez le conduit en cuivre dont la température classée à 60 ºC /75 ºC.)

 Make sure all the fittings are securely tightened. Failure in tightening may cause the device malfunction, fire, or
electric shock.
(Assurez-vous que tout le serrage est fermement serré. Manque de serrage peut causer mauvais fonctionnement
du dispositif, feu, ou commotion électrique.)
 Fixing fittings must be tightened to the specified tightening torque. Excessive tightening may cause damage to
terminals or screws.
(Fixation du serrage doit être serrée à couple de serrage spécifié. Serrage excessif peut endommager du terminal
ou vis.)
Insufficient tightening may cause the device malfunction, fire, or electric shock.
(Serrage insuffisant peut causer mauvais fonctionnement du dispositif, feu, ou commotion électrique.)
 If you use a twisted wire on the voltage input terminal, twist the wire end to prevent the thin wires (stick terminal)
from spreading out.
 Accessory of LAN port cap can be used for dust-proof.
 Please return the unit which you removed for wiring. The units are only support to be worked as EcoWebServerIII.
It will be not worked without using for EcoWebServerIII.
 Please do not replace for any unit of EcoWebServerIII. Operation verification of EcoWebServerIII is confirmed as
the purchase. It may cause a malfunction or failure if EcoWebServerIII is used in any other combination.
