APPLICATION AS DIRECTED

Drive controllers are components which are designed for installation in electrical systems or machinery.

They are not to be used as appliances. They are intended exclusively for professional and commercial

purposes according to EN 61000-3-2.

When installing the drive controllers in machines, commissioning (i.e. the starting of operation as

directed) is prohibited until it is proven that the machine complies with the regulations of the EC

Directive 98/37/EC (Machinery Directive); EN 60204 must be observed. Commissioning (i.e. starting

of operation as directed) is only allowed when there is compliance with the EMC Directive

(89/336/EEC).

The drive controllers meet the requirements of the Low Voltage Directive 73/23/EEC. The

harmonized standards of the series 61800-5-1 DIN/DIN VDE 0160 apply to the controllers.

NOTE: The availability of controllers is restricted according to EN 61800-3. These products can

cause radio interference in residential areas. In this case, special measures can be necessary.

ELECTRICAL CONNECTION

When working on live drive controllers, applicable national regulations for the prevention of accidents

(e.g. VBG 4) must be observed.

The electrical installation must be carried out according to the appropriate regulations (e.g. cable size,

fuses, PE connection).

This manual 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.

Suitable for use on a circuit capable of delivering not more than 5000 rms

symmetrical amperes, 240 V maximum (249 V devices) or 500 V maximum

(400/500 V devices) respectively.

6.0 INSTALLATION

NOTE: SM 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.

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 LEESON ELECTRIC FOR MORE

INFORMATION ON THE SUITABILITY OF A DRIVE TO A PAR TICULAR

ENVIRONMENT.

SM Series

™

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 drives models MUST be

mounted in a vertical position for proper heatsink cooling.

Maintain a minimum spacing around the drive of at least 1 inch (25mm) on each side and 2 inches

(50mm) 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 columns in Section 5.0 - SM Series

™

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 outside the enclosure, and the enclosure properties.

The SM 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

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 pr emature 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.

WARNING

7.0 INPUT AC POWER REQUIREMENTS

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 V OLTAGE 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 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.

7.1 INPUT VOLTAGE RATINGS

SM Series drives rated for 120 Vac, single phase, 50-60 Hz input will function with input voltage of 120

Vac (+10%, -15%), at 48 to 62 Hz.

SM Series drives rated for 208/240 Vac, single phase, 50-60 Hz input will function with input voltage of

208 to 240 Vac (+10%, -15%), at 48 to 62 Hz.

SM Series drives rated for 208/240 Vac, three phase, 50-60 Hz input will function with input voltage of

208 to 240 Vac (+10%, -15%), at 48 to 62 Hz.

SM Series drives rated for 400/480 Vac, three phase, 50-60 Hz input 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. See Section 15.0 - DESCRIPTION OF PARAMETERS.

DANGER

7.2 INPUT FUSING AND DISCONNECT REQUIREMENTS

A circuit breaker or a disconnect switch with fuses must be provided in accordance with the National

Electric Code (NEC) and all local codes. Refer to the following tables for proper fuse/circuit breaker

ratings and wire sizes.

FUSE, CIRCUIT BREAKER, AND WIRE SIZES (for installation to UL and EN 60204-1)

NOTE 1: Use UL Class CC fast-acting, current limiting type fuses. Select fuses with low 1

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.

NOTE 2: When using a pulse-current or universal-current sensitive ELCB (earth leakage circuit

breaker), the detection level must be rated 30mA or greater. Observe the following when using

ELCBs:

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

2. The ELCB 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

7.3 INSTALLATION ACCORDING TO EMC REQUIREMENTS

The SM Series

™

Series can be installed to meet the European stan-

dards 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: The input to the drive (or group of drives) must include a filter

to reduce the electrical noise reflected back to the AC Line.

Installation: Shielded cable must be used for all control and power

cables and exposed wiring must be kept as short as possible. The

figure to the right shows the control cable (B) and motor cable (C)

with the shield grounded with clamps (A) to a grounded, electrically conductive mounting panel (D).

The motor cable must be of a low capacitance specification:

core / core ≤ 75 pF/m, core/shield ≤ 150 pF/m

8.0 POWER WIRING

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.

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.

DANGER

CAUTION

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 9.0 - SM Series

™

POWER

WIRING DIAGRAM.

All three power output wires, from terminals U, V, and W 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 auxiliar y 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 U, V, or W, or

terminals B+, B-!. Severe damage to the drive will result.

NOTES:

1. WIRE AND GROUND IN ACCORDANCE WITH NEC OR CEC, AND ALL

APPLICABLE LOCAL CODES.

2. Motor wires MUST be run in a separate steel conduit away from control wiring and incoming

AC power wiring.

3. Do not install contactors between the drive and the motor without consulting LEESON

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

4. Use only UL and CSA listed and approved wire.

5. Minimum wire voltage rating is 300 V for 120, 208, and 240 Vac systems and 600 V for 400

and 480 Vac systems.

6. 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.

WARNING

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.

Strip off 0.20 to 0.25 inches (5 to 6 mm) of insulation for control wiring, and torque the control

terminals to 2 lb-in (0.2 Nm). Be careful not to overtorque the control 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 terminal is used as circuit common for the analog speed reference inputs. If necessary TB-2

may be connected to chassis ground.

10.3 SURGE SUPPRESSION 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 S tart/Stop cir cuits. Refer to the wiring

diagrams in Section 11.0 - SM Series

™

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 250 ohms.
