Installation & Safety Requirements

Ventilation Requirements

Ventilation Requirements

The instrument is fitted with three cooling fans. Make sure that there is
adequate clearance of 80 mm at the rear and 25 mm at the top and bot-
tom to ensure adequate air flow. If the air flow is restricted the internal
operating temperature will be higher, reducing the instrument’s reliabil-
ity or causing the instrument’s thermal-protection circuits to automati-
cally switch off the instrument.

NOTE:

Do not cover the ventilation holes.

Thermal Protection

Overheating Detection

The instrument monitors its internal temperature. If the temperature
exceeds approximately 80

°

C the power supply is switched off. The

instrument will switch on again if the temperature falls below approxi-
mately 77

°

C.

Fan Failure

If a fan is broken or prevented from operating by a blockage the temper-
ature will increase. When the temperature exceeds approximately 80

°

C

the overheating detection switches off the instrument for safety reasons.
For reliability it is recommended to send instruments with broken or
defective fans immediately to HP Service for repair.
