Altitude
Altitude range: 0 to 3,000 m (9,900 ft), subject to the following conditions:
1,000 m to 3,000 m (3,300 ft to 9,900 ft) above sea level: de-rate the maximum output current from
the specified figure by 1% per 100 m (330 ft) above 1,000 m (3,300 ft)
For example at 3,000 m (9,900 ft) the output current of the drive would have to be de-rated by 20 %.

IP / UL Rating
The drive is rated to IP20 pollution degree 2 (dry, non-conductive contamination only) (NEMA 1).
However, it is possible to configure the drive to achieve IP65 rating (NEMA 12) at the rear of the
heatsink for through-panel mounting (some current derating is required).
In order to achieve the high IP rating at the rear of the heatsink with drive size 5 it is necessary to
seal a heatsink vent by installing the high IP insert.
The IP rating of a product is a measure of protection against ingress and contact to foreign bodies
and water. It is stated as IP XX, where the two digits (XX) indicate the degree of protection provided
as shown in Table 5-12
