information
The dedicated drive compressor related functionality includes:
• Soft start
The initial start of the compressor, where the motor is accelerated to a predetermined dwell speed.
• Locked rotor
During a mechanical failure of compressor or associated system, a condition can occur where the motor cannot turn even with maximum current, this
is the locked rotor condition. It is detected by the software during soft start if the estimating motor speed is below 20% of the soft-start dwell speed.
• Motor phase loss detection
The drive will detect and trip if a phase connection to the motor is missing during soft-starting. After 5 minutes the trip is automatically reset and the
soft-start can begin once more. The system will lockout after 10 trips within a 24 hour period. The count of trips is reset on lockout.
• Envelope control
The compressor has a speed envelope in which normal operation takes place. Envelope control is used to keep the compressor operating within this
envelope. The software function receives both the condenser and evaporator pressures and limits the speed reference to keep the compressor
operating within its envelope. If operation outside the outer envelope is detected, a trip will occur to protect the compressor.
• Resonance avoidance
This is to avoid running at speeds where mechanical resonance effects are identified.
• Defrost cycle
During this mode of operation the compressor motor is changed to a defined speed for a period of time. This is to raise the temperature of the
evaporator and defrost it.
• Oil boost
If the compressor is running at a speed that is insufficient to guarantee lubrication (for a defined time) oil boost mode is entered. During oil boost the
motor speed is increased for a period of time to ensure the compressor is correctly lubricated.
• Lost rotor trip prevent
The drive automatically reduces the compressor speed under conditions where the speed error is greater than expected to avoid nuisance trips.

information
• Controlled shutdown
A controlled shutdown avoids compressor issues that would be caused by simply turning off the power. During a controlled shutdown, the motor
decelerates to a defined speed for a dwell time and then slows to zero speed at a controlled rate.
• Anti short cycling
Excessive short duration cycles can cause damage to the compressor and system. The short-cycle prevention scheme detects if there have been too
many short-cycles. It will alert the user and impose a restart lockout time to prevent further short-cycles.
• Discharge Line Temperature
The drive monitors the level of the discharge line temperature sensor and trips if it is outside of the permitted range.
• Stator Heating
This function feeds DC current through the motor stator windings in order to heat the compressor while the compressor is not spinning.
• Field-bus communications watchdog timer
This function may be used to protect the system from a long term loss of field-bus communications.
• Alert log
The last 20 alerts occurring within the last 7 days are logged for diagnostic purposes.

3 Mechanical installation
This chapter describes how to use all mechanical details to install the
drive. The drive is intended to be installed in an enclosure. Key features
of this chapter include:
• Through-hole mounting
• High IP as standard or through-panel mounting
• Enclosure sizing and layout
• Option module installing
• Terminal location and torque settings
3.1 Safety information
Follow the instructions
The mechanical and electrical installation instructions must
be adhered to. Any questions or doubt should be referred to
the supplier of the equipment. It is the responsibility of the
owner or user to ensure that the installation of the drive and
any external option unit, and the way in which they are
operated and maintained, comply with the requirements of
the Health and Safety at Work Act in the United Kingdom or
applicable legislation and regulations and codes of practice in
the country in which the equipment is used.
Competence of the installer
The drive must be installed by professional assemblers who
are familiar with the requirements for safety and EMC. The
assembler is responsible for ensuring that the end product or
system complies with all the relevant laws in the country
where it is to be used.
Enclosure
The drive is intended to be mounted in an enclosure which
prevents access except by trained and authorized
personnel, and which prevents the ingress of contamination.
It is designed for use in an environment classified as
pollution degree 2 in accordance with IEC 60664-1. This
means that only dry, non-conducting contamination is
acceptable.
3.2.3 Cooling
The heat produced by the drive must be removed without its specified
operating temperature being exceeded. Note that a sealed enclosure
gives much reduced cooling compared with a ventilated one, and may
need to be larger and/or use internal air circulating fans.
For further information, refer to section 3.6 Enclosure for standard
drives on page 30.
3.2.4 Electrical safety
The installation must be safe under normal and fault conditions.
Electrical installation instructions are given in Chapter 4 Electrical
installation on page 43.
3.2.5 Electromagnetic compatibility
Variable speed drives are powerful electronic circuits which can cause
electromagnetic interference if not installed correctly with careful
attention to the layout of the wiring.
Some simple routine precautions can prevent disturbance to typical
industrial control equipment.
If it is necessary to meet strict emission limits, or if it is known that
electromagnetically sensitive equipment is located nearby, then full
precautions must be observed. Built into the drive, is an internal EMC
filter, which reduces emissions under certain conditions. If these
conditions are exceeded, then the use of an external EMC filter may be
required at the drive inputs, which must be located very close to the
drives. Space must be made available for the filters and allowance made
for carefully segregated wiring. Both levels of precautions are covered in
section 4.6 EMC (Electromagnetic compatibility) on page 50.
3.2.6 Hazardous areas
The drive must not be located in a classified hazardous area unless it is
installed in an approved enclosure and the installation is certified.
3.2 Planning the installation
The following considerations must be made when planning the installation:
3.2.1 Access
Access must be restricted to authorized personnel only. Safety
regulations which apply at the place of use must be complied with.
The IP (Ingress Protection) rating of the drive is installation dependent.
For further information, refer to section 3.9 Enclosing standard drive for
high environmental protection on page 32.
3.2.2 Environmental protection
The drive must be protected from:
• Moisture, including dripping water or spraying water and
condensation. An anti-condensation heater may be required, which
must be switched off when the drive is running.
• Contamination with electrically conductive material
• Contamination with any form of dust which may restrict the fan, or
impair airflow over various components
• Temperature beyond the specified operating and storage ranges
• Corrosive gasses
During installation it is recommended that the vents on the drive are
covered to prevent debris (e.g. wire off-cuts) from entering the drive.

3.3 Terminal cover removal
Isolation device
The AC and / or DC power supply must be disconnected from the drive using an approved isolation device before any cover is removed
from the drive or before any servicing work is performed.
Stored charge
The drive contains capacitors that remain charged to a potentially lethal voltage after the AC and / or DC power supply has been
disconnected. If the drive has been energized, the power supply must be isolated at least ten minutes before work may continue.
Normally, the capacitors are discharged by an internal resistor. Under certain, unusual fault conditions, it is possible that the capacitors may
fail to discharge, or be prevented from being discharged by a voltage applied to the output terminals. If the drive has failed in a manner that
causes the display to go blank immediately, it is possible the capacitors will not be discharged. In this case, consult Emerson Climate
Technologies.

3.6 Enclosure for standard drives
3.6.1 Enclosure layout
Please observe the clearances in the diagram below taking into account
any appropriate notes for other devices / auxiliary equipment when
planning the installation.
Figure 3-15 Enclosure layout
For EMC compliance:
1. When using an external EMC filter, one filter is required for each drive.
2. Power cabling must be at least 100 mm (4 in) from the drive in all directions

3.6.2 Enclosure sizing
1. Add the dissipation figures from section on page 178 for each drive
that is to be installed in the enclosure.
2. If an external EMC filter is to be used with each drive, add the
dissipation figures from section 11.2.1 EMC filter ratings on
page 188 for each external EMC filter that is to be installed in the
enclosure.
3. Calculate the total heat dissipation (in Watts) of any other equipment
to be installed in the enclosure.
4. Add the heat dissipation figures obtained above. This gives a figure
in Watts for the total heat that will be dissipated inside the enclosure.
Calculating the size of a sealed enclosure
The enclosure transfers internally generated heat into the surrounding
air by natural convection (or external forced air flow); the greater the
surface area of the enclosure walls, the better is the dissipation
capability. Only the surfaces of the enclosure that are unobstructed (not
in contact with a wall or floor) can dissipate heat.
Calculate the minimum required unobstructed surface area A

Example
To calculate the size of an enclosure for the following:
• Two drives operating at the Normal Duty rating
• External EMC filter for each drive
• Maximum ambient temperature inside the enclosure: 40 °C
• Maximum ambient temperature outside the enclosure: 30 °C
For example, if the power dissipation from each drive is 187 W and the
power dissipation from each external EMC filter is 9.2 W.
Total dissipation: 2 x (187 + 9.2) =392.4 W
Power dissipation for the drives and the external EMC filters can be
obtained from Chapter 11 Technical data on page 177.
The enclosure is to be made from painted 2 mm (0.079 in) sheet steel
having a heat transmission coefficient of 5.5 W/m
2/o
C. Only the top,
front, and two sides of the enclosure are free to dissipate heat.
The value of 5.5 W/m
2
/ºC can generally be used with a sheet steel
enclosure (exact values can be obtained by the supplier of the material).
If in any doubt, allow for a greater margin in the temperature rise.
