Safety Guidelines
zFollow these guidelines to ensure general safety:
zKeep the chassis area clear and dust-free before, during and after installation.
zDo not wear loose clothing or jewelry that could get caught in the chassis. Fasten your tie or
scarf and roll up your sleeves.
zWear safety glasses/goggles if you are working under any conditions that might be hazardous
to your eyes.
zDo not perform any action that creates a potential hazard to people or makes the equipment
unsafe.
zDisconnect all power by turning off the power and unplugging the power cord before installing
or removing a chassis or working near power supplies
zDo not work alone if potentially hazardous conditions exist.
zNever assume that power is disconnected from a circuit; always check the circuit.
LITHIUM BATTERY CAUTION:
Risk of explosion could occur if battery is replaced by an incorrect type. Please dispose of used
batteries according to the recycling instructions of your country.
zInstallation only by a trained electrician or only by an electrically trained person who knows all
the applied or related installation and device specifications..
zDo not carry the handle of power supplies when moving to other place.
zThe machine can only be used in a fixed location such as labs or computer facilities.
Operating Safety
zElectrical equipment generates heat. Ambient air temperature may not be adequate to cool
equipment to acceptable operating temperatures without adequate circulation. Be sure that the
room in which you choose to operate your system has adequate air circulation.
zEnsure that the chassis cover is secure. The chassis design allows cooling air to circulate
effectively. An open chassis permits air leaks, which may interrupt and redirect the flow of
cooling air from internal components.
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD damage
occurs when electronic components are improperly handled and can result in complete or
intermittent failures. Be sure to follow ESD-prevention procedures when removing and replacing
components to avoid these problems.
zWear an ESD-preventive wrist strap, ensuring that it makes good skin contact. If no wrist strap

Industrial Communication Platform
5
is available, ground yourself by touching the metal part of the chassis.
zPeriodically check the resistance value of the antistatic strap, which should be between 1 and
10 megohms (Mohms).
Mounting Installation Environment Precaution
1. Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating
ambient temperature of the rack environment may be greater than room ambient. Therefore,
consideration should be given to installing the equipment in an environment compatible with the
maximum ambient temperature (Tma) specified by the manufacturer.
2. Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air
flow required for safe operation of the equipment is not compromised.
3. Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous
condition is not achieved due to uneven mechanical loading.
4. Circuit Overloading - Consideration should be given to the connection of the equipment to the
supply circuit and the effect that overloading of the circuits might have on over-current protection
and supply wiring. Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.
5. Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct connections to the
branch circuit (e.g. use of power strips).”
Consignes de sécurité
Suivez ces consignes pour assurer la securite generale :
zLaissez la zone du chassis propre et sans poussiere pendant et apres l’installation.
zNe portez pas de vetements amples ou de bijoux qui pourraient etre pris dans le chassis.
Attachez votre cravate ou echarpe et remontez vos manches.
zPortez des lunettes de securite pour proteger vosmyeux.
zN’effectuez aucune action qui pourrait creer un dangermpour d’autres ou rendre l’equipement
dangereux.
zCoupez completement l’alimentation en eteignant l’alimentation et en debranchant le cordon
d’alimentation avant d’installer ou de retirer un chassis ou de travailler a proximite de sources
d’alimentation.
zNe travaillez pas seul si des conditions dangereuses sont presentes.
zNe considerez jamais que l’alimentation est coupee d’un circuit, verifiez toujours le circuit. Cet
appareil genere, utilise et emet une energie radiofrequence et, s’il n’est pas installe et utilise
conformement aux instructions des fournisseurs de composants sans fil, il risque de

Industrial Communication Platform

provoquer des interferences dans les communications radio.
Avertissement concernant la pile au lithium
zRisque d’explosion si la pile est remplacee par une autre d’un mauvais type.
zJetez les piles usagees conformement aux instructions.
zL’installation doit etre effectuee par un electricien forme ou une personne formee a l’electricite
connaissant toutes les specifications d’installation et d’appareil du produit.
zNe transportez pas l’unite en la tenant par le cable d’alimentation lorsque vous deplacez
l’appareil.
zLa machine ne peut etre utilisee qu’a un lieu fixe comme en laboratoire, salle d’ordinateurs ou
salle de classe.
Sécurité de fonctionnement
zL’equipement electrique genere de la chaleur. La temperature ambiante peut ne pas etre
adequate pour refroidir l’equipement a une temperature de fonctionnement acceptable sans
circulation adaptee. Verifiez que votre site propose une circulation d’air adequate.
zVerifiez que le couvercle du chassis est bien fixe. La conception du chassis permet a l’air de
refroidissement de bien circuler. Un chassis ouvert laisse l’air s’echapper, ce qui peut
interrompre et rediriger le flux d’air frais destine aux composants internes.
zLes decharges electrostatiques (ESD) peuvent endommager l’equipement et gener les
circuits electriques. Des degats d’ESD surviennent lorsque des composants electroniques
sont mal manipules et peuvent causer des pannes totales ou intermittentes. Suivez les
procedures de prevention d’ESD lors du retrait et du remplacement de composants.
- Portez un bracelet anti-ESD et veillez a ce qu’il soit bien au contact de la peau. Si aucun bracelet
n’est disponible, reliez votre corps a la terre en touchant la partie metallique du chassis. Verifiez
regulierement la valeur de resistance du bracelet antistatique, qui doit etre comprise entre 1 et 10
megohms (Mohms).
Consignes de sécurité électrique
zAvant d’allumer l’appareil, reliez le cable de mise a la terre de l’equipement a la terre.
zUne bonne mise a la terre (connexion a la terre) est tres importante pour proteger l
equipement contre les effets nefastes du bruit externe et reduire les risques d’electrocution en
cas de foudre.
zPour desinstaller l’equipement, debranchez le cable de mise a la terre apres avoir eteint
l’appareil.
zUn cable de mise a la terre est requis et la zone reliant les sections du conducteur doit faire
plus de 4 mm2 ou 10 AWG.
