Tech's factory. If an SCF motor control, under normal use, becomes defective within the
stated warranty time period, contact Lenze AC Tech's Service Department for instructions on
obtaining a warranty replacement unit. Lenze AC Tech 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.
Lenze AC Tech 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,
firm or corporation is authorized to assume, for Lenze AC Tech 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
GENERAL
Some parts of Lenze 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 who are familiar with the installation,
assembly, commissioning, and operation of variable frequency drives and the application for
which it is being used.
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.

SF01U 3
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 UL508 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 Lenze AC Tech documentation.
The SCF 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 CE-marked 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.
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 and/or OEM and/or integrator to ensure that the drive is
configured for safe operation.
1.6 CUSTOMER MODIFICATION
Lenze AC Tech Corporation, its sales representatives and distributors, welcome the opportunity
to assist our customers in applying our products. Many customizing options are available to aid
in this function. Lenze AC Tech Corporation cannot assume responsibility for any modifications
not authorized by its engineering department

6.0 INSTALLATION
NOTE
SCF 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 Lenze
AC Tech for more information on the suitability of a drive to a particular
environment.
SCF models are suitable for UL pollution degree 2 environment only, and MUST be installed in
an electrical enclosure which 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 rated up to 5 HP (3.7 kW). For units rated
7.5 - 30 HP (5.5 - 22 kW), maintain at least 2 inches (50 mm) on each side and 4 inches (100
mm) on the top and bottom. 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 columns in Section 5.0 - SCF RATINGS. The STD column is for standard
units, and the THRU column is for through-hole mount units (drives with the through-hole
mount option still generate some heat inside the enclosure that must be taken into account).
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 SCF 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.

6.2 EXPLOSION PROOF APPLICATIONS
Explosion proof motors that are not rated for inverter use lose their certification when used
for variable speed. Due to the many areas of liability that may be encountered when dealing
with these applications, the following statement of policy applies:
“Lenze AC Tech Corporation inverter products are sold with no warranty of fitness for a
particular purpose or warranty of suitability for use with explosion proof motors. Lenze AC Tech
Corporation accepts no responsibility for any direct, incidental or consequential loss, cost, or
damage that may arise through the use of its AC inverter products in these applications. The
purchaser expressly agrees to assume all risk of any loss, cost, or damage that may arise
from such application."
7.0 INPUT AC POWER REQUIREMENTS
DANGER!
Hazard of electrical shock! Capacitors retain charge after power is removed.
Disconnect incoming power and wait until the voltage between terminals B+
and B- is 0 VDC before servicing the drive.
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 15.0 - DESCRIPTION OF PARAMETERS).
The drive is suitable for use on a circuit capable of delivering not more than 5,000 RMS
symmetrical amperes at 5 HP (3.7 kW) and below, and 18,000 RMS symmetrical amperes at
7.5 HP (5.5 kW) and above, 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’s power components.
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.

7.4 INSTALLATION ACCORDING TO EMC REQUIREMENTS
The SCF 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.

8.0 POWER WIRING
DANGER!
Hazard of electrical shock! Capacitors retain charge after power is removed.
Disconnect incoming power and wait until the voltage between terminals B+
and B- is 0 VDC before servicing the drive.
Note drive input and output current ratings and 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.
Refer to Section 9.0 - SCF POWER WIRING DIAGRAM for information on torque and wire
stripping requirements for power wiring.
Input fusing and a power disconnect switch or contactor MUST be wired in series with terminals
L1, L2, and L3 for three phase input models. For 208/240 Vac single phase input models, use
terminals L1 and L2. 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 WIRING FOR SINGLE PHASE OR THREE PHASE INPUT
If the drive is rated for single and three phase input (SF200Y models), wire to terminals L1 and
L2 for single phase input, or wire to terminals L1, L2, and L3 for three phase input.
If the drive is rated for three phase input, wire the input to terminals L1, L2, and L3.All three
power output wires, from terminals T1, T2, and T3 to the motor, must be kept tightly bundled
and run 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 (see 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.

DO NOT connect incoming AC power to output terminals T1, T2, T3, or
terminals B+, B-! Severe damage to the drive will result.
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.

10.0 CONTROL WIRING
10.1 CONTROL WIRING VS. POWER WIRING
External control wiring MUST be run in a separate conduit away from all other input and output
power wiring. If control wiring is not kept separate from power wiring, electrical noise may be
generated on the control wiring that will cause erratic drive behavior. Use twisted wires or
shielded cable grounded at the drive chassis ONLY. Recommended control wire is Belden
8760 (2-wire) or 8770 (3-wire), or equivalent.
NOTE
Control terminals provide basic isolation (insulation per EN 61800-5-1).
Protection against contact can only be assured by additional measures e.g.
supplemental insulation.
Strip off 0.20 to 0.25 inches (5 to 6 mm) of insulation for control wiring, and torque the terminals
to 2 lb-in (0.2 Nm). Be careful not to overtorque the terminals, as this will cause damage to
the terminal strip. This is not covered under warranty and can only be repaired by replacing
the control board.
10.2 TB-2: CIRCUIT COMMON
The TB-2 terminals are used as circuit common for the start/stop, forward/reverse, input
select, local/remote, analog input, and analog output functions. There are three TB-2 terminals
available on the terminal strip, and they are all internally connected to each other on the main
control board. If necessary TB-2 may be connected to chassis ground.
NOTE
TB-2 must be connected to chassis ground when using serial
communications.
10.3 SURGE SUPPRESION ON RELAYS
Current and voltage surges and spikes in the coils of contactors, relays, solenoids, etc, near
or connected to the drive, can cause erratic drive operation. Therefore, a snubber circuit
should be used on coils associated with the drive. For AC coils, snubbers should consist of
a resistor and a capacitor in series across the coil. For DC coils, a free-wheeling or flyback
diode should be placed across the coil. Snubbers are typically available from the manufacturer
of the device.
10.4 START/STOP CONTROL
There are various control schemes that allow for 2-wire and 3-wire Start/Stop circuits. Refer
to the wiring diagrams in Section 11.0 - SCF CONTROL WIRING DIAGRAMS
10.5 SPEED REFERENCE SIGNALS
The drive allows for three analog speed reference inputs:
SPEED POT Connect the wiper of a speed pot to terminal TB-5, and connect the high and
low end leads to terminals TB-6 and TB-2, respectively. The speed pot can
be 2.5kΩ up to 10kΩ.
0-10 VDC Wire the positive to terminal TB-5 and the negative to terminal TB-2. TB-5
input impedance is 120 kilohms.
4-20 mA Wire the positive to terminal TB-25 and the negative to terminal TB-2. TB-25
input impedance is 100 ohms.
