270 HVAC Drive H300
Issue Number: 3
Table 12-8 IP Rating degrees of protection
Table 12-9 UL enclosure ratings
12.1.10 Corrosive gasses
Concentrations of corrosive gases must not exceed the levels given in:
• Table A2 of EN 50178:1998
• Class 3C2 of IEC 60721-3-3
This corresponds to the levels typical of urban areas with industrial
activities and/or heavy traffic, but not in the immediate neighborhood of
industrial sources with chemical emissions.
12.1.11 RoHS compliance
The drive meets EU directive 2011/65/EU for RoHS compliance.
12.1.12 Vibration
Maximum recommended continuous vibration level 0.14 g r.m.s. broad-
band 5 to 200 Hz.
This is the limit for broad-band (random) vibration. Narrow-band
vibration at this level which coincides with a structural resonance could
result in premature failure.
Bump Test
Testing in each of three mutually perpendicular axes in turn.
Referenced standard:IEC 60068-2-29: Test Eb:
Severity: 18 g, 6 ms, half sine
No. of Bumps: 600 (100 in each direction of each axis)
Random Vibration Test
Testing in each of three mutually perpendicular axes in turn.
Referenced standard:IEC 60068-2-64: Test Fh:
Severity: 1.0 m²/s³ (0.01 g²/Hz) ASD from 5 to 20 Hz
-3 dB/octave from 20 to 200 Hz
Duration: 30 minutes in each of 3 mutually perpendicular axes.
Sinusoidal Vibration Test
Testing in each of three mutually perpendicular axes in turn.
Referenced standard: IEC 60068-2-6: Test Fc:
Frequency range: 5 to 500 Hz
Severity: 3.5 mm peak displacement from 5 to 9 Hz
10 m/s² peak acceleration from 9 to 200 Hz
15 m/s² peak acceleration from 200 to 500 Hz
Sweep rate: 1 octave/minute
Duration: 15 minutes in each of 3 mutually perpendicular axes.
EN 61800-5-1:2007, Section 5.2.6.4. referring to IEC 60068-2-6
Frequency range: 10 to 150 Hz
Amplitude: 10 to 57 Hz at 0.075 mm pk
57 to 150 Hz at 1g p
Sweep rate: 1 octave/minute
Duration: 10 sweep cycles per axis in each of 3 mutually
perpendicular axes
12.1.13 Starts per hour
By electronic control: unlimited
By interrupting the AC supply: ≤20 (equally spaced)
12.1.14 Start up time
This is the time taken from the moment of applying power to the drive, to
the drive being ready to run the motor:
Sizes 3 to 6 = 2.5 s
Sizes 7 to 11 = 5 s
12.1.15 Output frequency / speed range
In all operating modes (Open loop, RFC-A, RFC-S) the maximum output
frequency is limited to 550 Hz.
12.1.16 Accuracy and resolution
Speed:
The absolute frequency and speed accuracy depends on the accuracy
of the crystal used with the drive microprocessor. The accuracy of the
crystal is 100 ppm, and so the absolute frequency/speed accuracy is
100 ppm (0.01 %) of the reference, when a preset speed is used. If an
analog input is used the absolute accuracy is further limited by the
absolute accuracy of the analog input.
The following data applies to the drive only; it does not include the
performance of the source of the control signals.
Open loop resolution:
Preset frequency reference: 0.1 Hz
Precision frequency reference: 0.001 Hz
Closed loop resolution
Preset speed reference: 0.1 rpm
Precision speed reference: 0.001 rpm
Analog input 1: 11 bit plus sign
Analog input 2: 11 bit plus sign
Current:
The resolution of the current feedback is 10 bit plus sign.
Accuracy: typical 2 %
worst case 5 %

UL rating Description
Type 1
Enclosures are intended for indoor use, primarily
to provide a degree of protection against limited
amounts of falling dirt.
Type 12
Enclosures are intended for indoor use, primarily
to provide a degree of protection against dust,
falling dirt and dripping non-corrosive liquids.
