1 GENERAL

1.1 Products Covered in This Manual

This manual covers the AC Tech SCL and SCM Series Variable Frequency Drives.

1.2 Product Changes

AC Technology Corporation reserves the right to discontinue or make modifications to the
design of its products without prior notice, and holds no obligation to make modifications
to products sold previously. AC Technology Corporation also holds no liability for losses
of any kind which may result from this action. Instruction manuals with the most up-to-date
information are available for download from the AC Tech website (www.actech.com).

1.3 Warranty

AC Technology Corporation warrants the SCL/SCM Series AC motor control to be free of
defects in material and workmanship for a period of 24 months from the date of shipment
from AC Tech's factory. If, under normal use, an SCL/SCM motor control becomes defective
within the stated warranty time period, contact AC Technology's Service Department for
instructions on obtaining a warranty replacement unit. AC Technology Corporation reserves
the right to make the final determination as to the validity of a warranty claim, and sole
obligation is to repair or replace only components which have been rendered defective
due to faulty material or workmanship. No warranty claim will be accepted for components
which have been damaged due to mishandling, improper installation, unauthorized repair
and/or alteration of the product, operation in excess of design specifications or other
misuse, or improper maintenance. AC Technology Corporation makes no warranty that its
products are compatible with any other equipment, or to any specific application, to which
they may be applied and shall not be held liable for any other consequential damage or
injury arising from the use of its products.

This warranty is in lieu of all other warranties, expressed or implied. No other person,
rm or corporation is authorized to assume, for AC Technology Corporation, any
other liability in connection with the demonstration or sale of its products.

1.4 Receiving

Inspect all cartons for damage which may have occurred during shipping. Carefully
unpack equipment and inspect thoroughly for damage or shortage. Report any damage
to carrier and/or shortages to supplier. All major components and connections should be
examined for damage and tightness, with special attention given to PC boards, plugs,
knobs and switches.

1.5 Safety Information

Some parts of AC Tech controllers can be electrically live and some surfaces can be hot.
Non-authorized removal of the required cover, inappropriate use, and incorrect installation
or operation creates the risk of severe injury to personnel or damage to equipment. All
operations concerning transport, installation, and commissioning as well as maintenance
must be carried out by qualified, skilled personnel familiar with the installation, assembly,
commissioning, and operation of variable frequency drives and the application in which
the drive is used.

3 SM01M

INSTALLATION

Ensure proper handling and avoid excessive mechanical stress. Do not bend any
components and do not change any insulation distances during transport, handling,
installation or maintenance.

Do not touch any electronic components or contacts. This drive contains electrostatically
sensitive components, which can easily be damaged by inappropriate handling. Static
control precautions must be adhered to during installation, testing, servicing and repairing
of this drive and associated options. Component damage may result if proper procedures
are not followed.

This drive has been tested by Underwriters Laboratory (UL) and is an approved component
in compliance with UL508C Safety Standard.

Warnings!

• Suitable for use on a circuit as described in Section 7.0 of this manual.

• Use minimum 75°C copper wire only.

• Shall be installed in a Pollution Degree 2 macro-environment.

This drive must be installed and configured in accordance with both national and international
standards. Local codes and regulations take precedence over recommendations provided
in this and other AC Tech documentation.

The drive is considered a component for integration into a machine or process. It is neither
a machine nor a device ready for use in accordance with European directives (reference
machinery directive and electromagnetic compatibility directive). It is the responsibility of
the end user to ensure that the machine meets the applicable standards.

ELECTRICAL CONNECTION

When working on live drive controllers, applicable national safety regulations must be
observed. The electrical installation must be carried out according to the appropriate
regulations (e.g. cable cross-sections, fuses, protective earth [PE] connection). While
this document does make recommendations in regards to these items, national and local
codes must be adhered to.

The documentation contains information about installation in compliance with EMC
(shielding, grounding, filters and cables). These notes must also be observed for CE­marked controllers. The manufacturer of the system or machine is responsible for
compliance with the required limit values demanded by EMC legislation.

APPLICATION

The drive must not be used as a safety device for machines where there is a risk of
personal injury or material damage. Emergency Stops, over-speed protection, acceleration
and deceleration limits, etc must be made by other devices to ensure operation under
all conditions.

SM01M 4

The drive does feature many protection devices which are aimed at protecting the drive
and the driven equipment by generating a fault and shutting the drive and motor down by
removing power. Mains power variances can also result in shutdown of the drive. When
the fault condition disappears or is cleared, the drive can be configured to automatically
restart, it is the responsibility of the user, OEM and/or integrator to ensure that the drive
is configured for safe operation.

1.6 Customer Modication

AC Technology Corporation, its sales representatives and distributors, welcome the
opportunity to assist our customers in applying our products. Many custom options are
available to aid in this function. AC Technology Corporation cannot assume responsibility
for any modifications not authorized by its engineering department.

6 INSTALLATION

NOTE

SCL/SCM Series drives are intended for inclusion within other equipment, by
professional electrical installers according to EN 61000-3-2. They are not intended
for stand-alone operation.

WARNING!

Drives must not be installed where subjected to adverse environmental conditions
such as: combustible, oily, or hazardous vapors or dust; excessive moisture or
dirt; vibration; excessive ambient temperatures. Consult AC Technology for more
information on the suitability of a drive to a particular environment.

SCL/SCM models are suitable for UL Pollution Degree 2 environment only, and MUST be
installed in an electrical enclosure that will provide complete mechanical protection and will
maintain the internal temperature within the drive’s ambient operating temperature rating.
All drive models MUST be mounted in a vertical position for proper heatsink cooling.

Maintain a minimum spacing around the drive of at least 1 inch (25 mm) on each side and
2 inches (50 mm) on the top and bottom for units up to 5 Hp (4 kW), and 2 inches (50 mm)
on each side and 4 inches (100 mm) on the top and bottom for larger units. Allow more
spacing if the drive is mounted next to other heat-producing equipment. Do not mount
drives above other drives or heat producing equipment. Fans or blowers should be used
to insure proper cooling in tight quarters.

In order to properly size an enclosure, the heat generated by the drive(s) must be known.
Refer to the HEAT LOSS column in Section 5.0, SCL/SCM RATINGS. An enclosure
manufacturer can then determine the required enclosure size based on the total heat
generated inside the enclosure (from the drive(s) and other heat sources), the maximum
allowable temperature inside the enclosure, the maximum ambient temperature outside
the enclosure, and the enclosure properties.

The SCL/SCM Series is UL approved for solid state motor overload protection. Therefore,
a separate thermal overload relay is not required for single motor applications.

6.1 Installation After a Long Period of Storage

STOP!

Severe damage to the drive can result if it is operated after a long period of storage
or inactivity without reforming the DC bus capacitors!

If input power has not been applied to the drive for a period of time exceeding three years
(due to storage, etc), the electrolytic DC bus capacitors within the drive can change
internally, resulting in excessive leakage current. This can result in premature failure of
the capacitors if the drive is operated after such a long period of inactivity or storage.

In order to reform the capacitors and prepare the drive for operation after a long period of
inactivity, apply input power to the drive for 8 hours prior to actually operating the motor.

SM01M 10

7 INPUT AC POWER REQUIREMENTS

DANGER!

Hazard of electrical shock! Capacitors retain charge after power is removed. Before
servicing the drive, disconnect incoming power and wait until the voltage between
terminals B+ and B- is 0 VDC.

The input voltage must match the nameplate voltage rating of the drive. Voltage fluctuation
must not vary by greater than 10% overvoltage or 15% undervoltage.

NOTE

Drives with dual input voltage ratings must be programmed for the proper supply
voltage (refer to Parameter 01 - LINE VOLTAGE SELECTION in Section 15,
DESCRIPTION OF PARAMETERS).

The drive is suitable for use on a circuit capable of delivering not more than 5,000 RMS
symmetrical amperes at the drive’s rated voltage.

If the kVA rating of the AC supply transformer is greater than 10 times the input kVA rating
of the drive(s), an isolation transformer or 2-3% input line reactor must be added to the
line side of the drive(s).

Three phase voltage imbalance must be less than 2.0% phase to phase. Excessive phase
to phase imbalance can cause severe damage to the drive.

Motor voltage should match line voltage in normal applications. The drive’s maximum
output voltage will equal the input voltage. Use extreme caution when using a motor with
a voltage rating which is different from the input line voltage.

7.1 Input Voltage Ratings

SM000S Series drives are rated for 120 Vac single phase, 50-60 Hz input. The drive will

function with input voltage of 120 Vac (+10%, -15%) at 48 to 62 Hz.

SM200S & SL200S Series drives are rated for 208/240 Vac, single phase, 50-60 Hz
input. The drive will function with input voltage of 208 to 240 Vac (+10%, -15%), at 48
to 62 Hz.

SM200 Series drives are rated for 208/240 Vac, three phase, 50-60 Hz input. The drive
will function with input voltage of 208 to 240 Vac (+10%, -15%) at 48 to 62 Hz.

SM400 Series drives are rated for 400/480 Vac, three phase, 50-60 Hz input. The drive
will function with input voltage of 400 to 480 Vac (+10%, -15%) at 48 to 62 Hz.

NOTE

Parameter 01 - LINE VOLTAGE SELECTION must be programmed according to the
applied input voltage. Refer to Section 15, DESCRIPTION OF PARAMETERS.

T values, rated at 200,000 AIC. Recommended fuses are Bussman KTK-R,
JJN, and JJS. Similar fuses with equivalent ratings by other manufacturers may
also be acceptable.

WARNING!

This product can cause a DC current in the protective conductor. Where a residual
current device (RCD) is used for protection in case of direct or indirect contact, only
an RCD of Type B is allowed on the supply side of this product. Otherwise, another
protective measure shall be applied, such as separation from the environment
by double or reinforced insulation, or isolation from the supply system by a
transformer.

Observe the following when using RCDs:

1. Only install the RCD between the supply mains and drive controller.

2. The RCD can be activated by:

- capacitive leakage currents between the cable screens during operation
(especially with long, screened motor cables)

- connecting several drives to the mains at the same time

- additional RFI filters

7.4 Installation According to EMC Requirements

The SCM and SCL Series can be installed to meet the European standards for
Electromagnetic Compatibility (EMC) requirements. These requirements govern the
permissible electromagnetic emissions and immunity, both radiated and conducted, of
a drive system.

The EMC requirements apply to the final installation in its entirety, not to the individual
components used. Because every installation is different, the recommended installation
should follow these guidelines as a minimum. Additional equipment (such as ferrite core
absorbers on power conductors) or alternative wiring practices may be required to meet
conformance in some installations.

Filter: T

he input to the drive (or group of drives) must include a filter to reduce the electrical
noise reflected back to the AC Line. The SCL Series includes a filter that has been tested
to meet the industrial standards set by the EU, EN 61800-3 for conducted emissions and
EN 55011 for radiated emissions to class A compliance when installed in a control cabinet
with a motor cable < 10m. The SCM can be installed to meet these same standards when
used with an appropriately installed external line filter.

EMC
Compliance with EN 61800-3/A11

8 POWER WIRING

DANGER!

Hazard of electrical shock! Capacitors retain charge after power is removed. Before
servicing the drive, disconnect the incoming power and wait until the voltage between
terminals B+ and B- is 0 VDC.

Note the drive input and output current ratings and the check applicable electrical codes for
required wire type and size, grounding requirements, over-current protection, and incoming
power disconnect, before wiring the drive. Size conservatively to minimize voltage drop.

Input fusing and a power disconnect switch or contactor MUST be wired in series with
terminals L1 and L2/N (on single-phase input models), or terminals L1, L2, and L3 (on
three-phase input models). This disconnect must be used to power down the drive when
servicing, or when the drive is not to be operated for a long period of time, but should not
be used to start and stop the motor.

Repetitive cycling of a disconnect or input contactor (more than once every two
minutes) may cause damage to the drive.

8.1 Input and Output Wiring

On single phase input models, wire the input power to terminals L1 and L2/N. On three
phase input models, wire the input power to terminals L1, L2, and L3. Refer to Section 9,
SCL/SCM POWER WIRING DIAGRAM.

Keep all three power output wires, from terminals U, V, and W to the motor, tightly bundled
and run them in a separate conduit away from all other power and control wiring.

It is not recommended to install contactors or disconnect switches between the drive and
motor. Operating such devices while the drive is running can potentially cause damage
to the drive's power components. If such a device is required, it should only be operated
when the drive is in a STOP state. If there is potential for the device to be opened while
the drive is running, the drive must be programmed for COAST to stop (refer to Parameter
4 - STOP METHOD), and an auxiliary contact on the device must be interlocked with the
drive's run circuit. This will give the drive a stop command at the same time the device
opens, and will not allow the drive to start again until the device is closed.

• Leakage current may exceed 3.5 mA AC. Minimum size of the protective earth
(PE) conductor shall comply with local safety regulations for high leakage current

equipment.

NOTE

• WIRE AND GROUND IN ACCORDANCE WITH NEC OR CEC, AND ALL

APPLICABLE LOCAL CODES.

• Motor wires MUST be run in a separate steel conduit away from control wiring

and incoming AC power wiring.

• Do not install contactors between the drive and the motor without consulting AC

Technology for more information. Failure to do so may result in drive damage.

• Use only UL and CSA listed and approved wire.

• Minimum wire voltage rating is 300 V for 120, 208, and 240 Vac systems, and

600 V for 400 and 480 Vac systems.

• Wire gauge must be based on a minimum of 125% of the rated input/output current

of the drive, and a minimum 75°C insulation rating. Use copper wire only.
