Damage caused by overheating
Overheating can cause system damage.
• Install the components with the specified orientation.
• Maintain the minimum clearances to other components.
• Install suitable ventilation in the cabinet to dissipate the power loss of the individual
components.
• Install suitable air filters and keep the heat sink clean.
• Ensure that the components are provided with adequate cooling air through the cooling
openings. In particular, the connected signal and power cables must not cover the
ventilation openings.
• Ensure that the cooling air flow is not blocked by other devices or mix with the exhaust
air from other devices. If necessary, insert air baffles.
