Derating Guidelines for High Altitude
The drive can be used without derating at a maximum altitude of
1000 m (3300 ft). If the drive is used above 1000 m (3300 ft):
• Derate the maximum ambient temperature by 5

C (9

F) for every
additional 1000 m (3300 ft), subject to limits listed in the Altitude Limit
(Based on Voltage) table below.
Or
• Derate the output current by 10% for every additional 1000 m (3300 ft),
up to 3000 m (9900 ft), subject to limits listed in the
Altitude Limit
(Based on Voltage) table below.
High Altitude
Debris Protection
Take precautions to prevent debris from falling through the vents of the drive
housing during installation.
Storage
• Store within an ambient temperature range of -40...85

C
(1)
.
• Store within a relative humidity range of 0...95%, noncondensing.
• Do not expose to a corrosive atmosphere.
(1) The maximum ambient temperature for storing a Frame E drive is 70

C.
