Operating Limits A-5

Technical Specifications and Operating Limits

Operating Limits

The ambient temperature specification is measured at the front door

inlet. The site must have air conditioning of the correct size and

placement to maintain the specified ambient temperature range. The

air conditioning must be able to handle the BTU requirements of the

DPEs.

The operating limits listed above for temperature and humidity must not be

exceeded inside the closed cabinet in which the DPE and any DAEs are

mounted. Mounting equipment in a cabinet directly above or below a DPE

does not restrict air flow to the DPE because air flows through th e DPE from

front to back. Cabinet doors must not impede the front-to-back air flow.

Requirement Description

Ambient temperature 10°C to 40°C (50°F to 104°F)

Temperature gradient 10°C/hr (50°F/hr)

Relative humidity 20% to 80% noncondensing

Elevation 2438 m (8,000 ft) at 40°C; 3077 m (10,000 ft) at 37°C

Drive module power 25 W drive slot maximum (seeking)
