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 7) (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 sizes 3,4 and 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 12-1.
Table 12-1 IP Rating degrees of protection
First digit Second digit
Protection against contact and ingress of foreign bodies Protection against ingress of water
0 No protection 0 No protection
1
Protection against large foreign bodies φ > 50 mm (large area
contact with the hand)
1 Protection against vertically falling drops of water
2
Protection against medium size foreign bodies φ > 12 mm
(finger)
2 Protection against spraywater (up to 15 ° from the vertical)
3 Protection against small foreign bodies φ > 2.5 mm (tools, wires) 3 Protection against spraywater (up to 60 ° from the vertical)
4
Protection against granular foreign bodies φ > 1mm (tools,
wires)
4 Protection against splashwater (from all directions)
5
Protection against dust deposit, complete protection against
accidental contact.
5
Protection against heavy splash water (from all directions, at high
pressure)
6
Protection against dust ingress, complete protection against
accidental contact.
6 Protection against deckwater (e.g. in heavy seas)
7
7 Protection against immersion
8
8 Protection against submersion
