Dry bulb temperature is the regular ambient temperature. Derate maximum dry bulb temperature 1°C/300 m above 900 m. b. Must be noncondensing environment. c. With installed media, the minimum temperature is 10°C and maximum relative humidity is limited to 80%. Specific media requirements may vary. d. Allowable: equipment design extremes as measured at the equipment inlet. e. Recommended: target facility design and operational range.

There are two columns of power numbers (Watts). The Power Breaker column shows the power used to size the wall breaker at the installation site. The Typical Power column shows typical power. Typical power numbers may be used to assess average utility cost of cooling and electrical power. These tables also show the recommended breaker sizes for 4-wire and 5-wire sources 124 Chapter 4
