Issue Number: 2

panel mounted
12.1.3 Supply requirements
AC supply voltage:
200 V drive: 200 V to 240 V ±10 %
400 V drive: 380 V to 480 V ±10 %
575 V drive: 500 V to 575 V ±10 %
690 V drive: 500 V to 690 V ±10 %
Number of phases: 3
Maximum supply imbalance: 2 % negative phase sequence (equivalent
to 3 % voltage imbalance between phases).
Frequency range: 45 to 66 Hz
For UL compliance only, the maximum supply symmetrical fault current
must be limited to 100 kA.
12.1.4 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 175 kVA:
03200066, 03200080, 03200110, 03200127
03400034, 03400045, 03400062, 03400077
Model sizes 03400104 to 07600730 have an internal DC choke and
model sizes 08201490 to 0801080 and frame 9A have internal AC line
chokes so they do not require AC line reactors except for cases of
excessive phase unbalance or extreme supply conditions. Drive sizes
9E,10E and 11E do not have internal input line reactors hence an
external input line reactor must be used. For more information refer to
section 4.2.3 Input line reactor specification for size 9E, 10E and 11E on
page 78.
When required, each drive must have its own reactor(s). Three individual
reactors or a single three-phase reactor should be used.
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
12.1.5 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
12.1.6 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)
12.1.7 Storage
-40 °C (-40 °F) to +55 °C (131 °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.
12.1.8 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 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 %.
12.1.9 IP / UL Rating
The drive is rated to IP21 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 IP54 rating (size 9, 10 and
11) (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
12-8 IP Rating degrees of protection on page 243.
