Line reactors
Input line reactors reduce the risk of damage to the drive resulting from
poor phase balance or severe disturbances on the supply network.
Where line reactors are to be used, reactance values of approximately
2% are recommended. Higher values may be used if necessary, but may
result in a loss of drive output (reduced torque at high speed) because of
the voltage drop.
For all drive ratings, 2% line reactors permit drives to be used with a
supply unbalance of up to 3.5% negative phase sequence (equivalent to
5% voltage imbalance between phases).
Severe disturbances may be caused by the following factors, for example:
•
Power factor correction equipment connected close to the drive.
•
Large DC drives having no or inadequate line reactors connected to
the supply.
•
Across the line (DOL) started motor(s) connected to the supply such
that when any of these motors are started, the voltage dip exceeds
20%
Such disturbances may cause excessive peak currents to flow in the
input power circuit of the drive. This may cause nuisance tripping, or in
extreme cases, failure of the drive.
Drives of low power rating may also be susceptible to disturbance when
connected to supplies with a high rated capacity.
Line reactors are particularly recommended for use with the following
drive models when one of the above factors exists, or when the supply
capacity exceeds 175kVA:

reactors except for cases of excessive phase unbalance or extreme
supply conditions.
When required each drive must have its own reactor(s). Three individual
reactors or a single three-phase reactor should be used.
Reactor current ratings
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

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)

(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.

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%.

IP / UL Rating
The Unidrive SP 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).
