8.6 Temperature and humidity
Ambient temperature operating range:
0 °C to 55 °C (32 °F to 131 °F)
Field output current derating must be applied at temperature >40 °C (104 °F).
Minimum temperature at power-up:
The FXMP25 will power up at -15 °C (5 °F).
Maximum humidity:
The FXMP25 can operate in environments up to a maximum relative humidity: 90 %
non-condensing at 50 °C.
8.7 Storage
Storage temperature range: -40 to 70 °C.
Storage time is 2 years.
Electrolytic capacitors in any electronic product have a storage period after which they
require reforming or replacing.
The DC bus capacitors have a storage period of 10 years.
The low voltage capacitors on the control supplies typically have a storage period of 2
years and are thus the limiting factor.
Low voltage capacitors cannot be reformed due to their location in the circuit and thus
may require replacing if the FXMP25 is stored for a period of 2 years or greater without
power being applied.
It is therefore recommended that the FXMP25 is powered up for a minimum of 1 hour
after every 2 years of storage.
This process allows the FXMP25 to be stored for a further 2 years.
8.8 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 100m (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 %.
8.9 IP rating
The FXMP25 is rated to IP20 pollution degree 2 (dry, non-conductive contamination
only).
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 8-4.
