12 Technical Data
12.1 Motor requirements
No. of phases: 3
Maximum voltage:
200 V drive: 240 V
400 V drive: 480 V
575 V drive: 575 V
690 V drive: 690 V
12.2 Temperature, humidity and cooling method
Ambient temperature operating range:
- 20 °C to 50 °C (- 4 °F to 122 °F).
Output current derating must be applied at ambient temperatures >40 °C (104 °F).
Cooling method: Forced convection
Maximum humidity: 95 % non-condensing at 40 °C (104 °F)
12.3 Storage
-40 °C (-40 °F) to +50 °C (122 °F) for long term storage, or to +70 °C (158 °F) for short term storage.
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 drive is stored for a period of 2
years or greater without power being applied.
It is therefore recommended that drives are powered up for a minimum of 1 hour after every 2 years of storage.
This process allows the drive to be stored for a further 2 years.
12.4 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 %.
12.5 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 (sizes 3 to 8) or IP55 rating (size 9 to 11) (NEMA 12) at the rear of the heatsink for through-panel mounting.
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 12-1.
Table 12-1 IP Rating degrees of protection
First digit Second digit
Protection against foreign bodies and access to hazardous parts Protection against ingress of water
0 Non-protected 0 Non-protected
1
Protected against solid foreign objects of 50 mm Ø and greater
(back of a hand)
1 Protected against vertically falling water drops
2
Protected against solid foreign objects of 12.5 mm Ø and
greater (finger)
2
Protected against vertically falling water drops when enclosure
tilted up to 15°
3
Protected against solid foreign objects of 2.5 mm Ø and greater
(tool)
3 Protected against spraying water
4
Protected against solid foreign objects of 1.0 mm Ø and greater
(wire)
4 Protected against splashing water
5 Dust-protected (wire) 5 Protected against water jets
6 Dust-tight (wire) 6 Protected against powerful water jets
7 - 7 Protected against the effects of temporary immersion in water
8 - 8 Protected against the effects of continuous immersion in water
