2.8Environmental specifications

2.8.1Ambient temperature

Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Actual drive case temperature should not exceed 69°C (156°F) within the operating ambient conditions.

Above 1,000 feet (305 meters), the maximum temperature is derated linearly to 112°F (44°C) at 10,000 feet (3,048 meters).

Operating:

0° to 60°C (32° to 140°F)

 

 

Nonoperating:

–40° to 70°C (–40° to 158°F)

 

 

2.8.2Temperature gradient

Operating:

20°C per hour (68°F per hour max), without condensation

 

 

Nonoperating:

30°C per hour (86°F per hour max)

 

 

2.8.3Humidity

2.8.3.1Relative humidity

Operating:

5% to 95% noncondensing (30% per hour max)

 

 

Nonoperating:

5% to 95% noncondensing (30% per hour max)

 

 

2.8.3.2Wet bulb temperature

Operating:

37.7°C (99.9°F max)

 

 

Nonoperating:

40°C (104°F max)

 

 

2.8.4Altitude

Operating:

–60.96 m to 3,048 m (–200 ft. to 10,000+ ft.)

 

 

Nonoperating:

–60.96 m to 12,192 m (–200 ft. to 40,000+ ft.)

 

 

2.8.5Shock

All shock specifications assume that the drive is mounted securely with the input shock applied at the drive mounting screws. Shock may be applied in the X, Y or Z axis.

2.8.5.1Operating shock

These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 70 Gs based on half-sine shock pulses of 2 msec. Shocks should not be repeated more than two times per second.
