Electrical 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.
Ensure 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.
Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. If no wrist strap is available,
ground yourself by touching the metal part of the chassis.
Periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohms
(Mohms).
L’équipement électrique génère de la chaleur. La température ambiante peut ne pas être adéquate pour
refroidir l’équipement à une température de fonctionnement acceptable sans circulation adaptée. Vérifiez
que votre site propose une circulation d’air adéquate.
Vérifiez que le couvercle du châssis est bien fixé. La conception du châssis permet à l’air de refroidissement
de bien circuler. Un châssis ouvert laisse l’air s’échapper, ce qui peut interrompre et rediriger le flux d’air frais
destiné aux composants internes.
Les décharges électrostatiques (ESD) peuvent endommager l’équipement et gêner les circuits électriques.
Des dégâts d’ESD surviennent lorsque des composants électroniques sont mal manipulés et peuvent causer
des pannes totales ou intermittentes. Suivez les procédures de prévention d’ESD lors du retrait et du
remplacement de composants.
Portez un bracelet anti-ESD et veillez à ce qu’il soit bien au contact de la peau. Si aucun bracelet n’est
disponible, reliez votre corps àla terre en touchant la partie métallique du châssis.
Vérifiez régulièrement la valeur de résistance du bracelet antistatique, qui doit être comprise entre 1 et 10
mégohms (Mohms).
