If the Unidrive SPM 24V power supply (CT part number 8510-0000) is
used to supply the Unidrive SPMA/D or SPMC/U fusing is not required.

14.1.5 Additional line reactors
Reactor current ratings
See section 6.2.3 Supplies requiring additional line reactance on
page 68.
The current rating of the line reactors should be as follows:
Continuous current rating:
Not less than the continuous input current rating of the drive
Repetitive peak current rating:
Not less than twice the continuous input current rating of the drive
14.1.6 Motor requirements
No. of phases: 3
Maximum voltage:
Unidrive SPM (200V): 240V
Unidrive SPM (400V): 480V
Unidrive SPM (690V): 690V
14.1.7 Temperature, humidity and cooling method
Ambient temperature operating range:
0°C to 50°C (32°F to 122°F).
Output current derating must be applied at ambient temperatures
>40°C (104°F).
Minimum temperature at power-up:
-15°C (5°F), the supply must be cycled when the drive has warmed
up to 0°C (32°F).
Cooling method: Forced convection
Maximum humidity: 95% non-condensing at 40°C (104°F)
14.1.8 Storage
-40
o
C (-40
o
F) to +50
o
C (122
o
F) for long term storage, or to +70°C
(158°F) for short term storage.
14.1.9 Altitude
Altitude range: 0 to 3,000m (9,900 ft), subject to the following conditions:
1,000m to 3,000m (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 1,000m (3,300 ft)
For example at 3,000m (9,900ft) the output current of the drive would
have to be de-rated by 20%.
14.1.10 IP Rating (Ingress Protection)
The Unidrive SPM is rated to IP20 pollution degree 2 (dry, non-
conductive contamination only) (NEMA 1). However, it is possible to
configure the drive to achieve IP54 rating (NEMA 12) at the rear of the
heatsink for through-panel mounting (some current derating is required,
and the fan requires changing on SPMC/U).
