6.0INSTALLATION
NOTE: SM-Plus™ drives are intended for inclusion within other equipment, by professional electrical installers. 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 PARTICULAR ENVIRONMENT.
SM-Plus™ 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 rated up to 5 HP (3.7 kW). For units rated 7.5 - 25 HP (5.5- 18.5 kW), maintain at least 2 inches (50mm) on each side and 4 inches (100mm) 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 - SM-Plus™ 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-Plus™ is UL approved for solid state motor overload protection. Therefore, a separate thermal overload relay is not required for single motor applications.
6.1INSTALLATION 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 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.
8
6.2EXPLOSION 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:
“LEESON Electric inverter products are sold with no warranty of fitness for a particular purpose or warranty of suitability for use with explosion proof motors. LEESON Electric 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.”
7.0INPUT 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 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.
9
7.1INPUT VOLTAGE RATINGS
Drives are rated for 120/208/240 Vac, single phase, 50-60 Hz input. The drive will function with input voltage of 120 Vac (+10%, -15%), at 48 to 60 Hz, or with input voltage of 208 to 240 Vac (+10%, -15%), at 48 to 62 Hz.
Drives that are rated for 208/240 Vac, three phase, 50-60 Hz input will function with input voltages of 208 to 240 Vac (+10%, -15%), at 48 to 62 Hz.
Drives that are rated for 208/240 Vac, single or three phase, 50-60 Hz input will function with input voltage of 208 to 240 Vac (+10%, -15%), at 48 to 62 Hz.
Drives that are rated for 400/480 Vac, three phase, 50-60 Hz input will function with input voltages of 400 to 480 Vac (+10%, -15%), at 48 to 62 Hz.
Drives that are rated for 480/590 Vac, three phase, 50-60 Hz input will function with input voltages of 480 to 590 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.

NOTE 1: Applicable national and local electrical codes take precedence over recommendations in this table.
NOTE 2: Use UL Class CC or Class T fast-acting, current limiting type fuses. Select fuses with low I2T 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.
11
8.0POWER 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.
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. For 120 Vac single phase input models, use terminals L1 and N. 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.
8.1WIRING FOR SINGLE PHASE OR THREE PHASE INPUT
If the drive is rated for 120/208/240 Vac single phase input, wire the input to terminals L1 and N for 120 Vac voltage, or wire to terminals L1 and L2 (do not wire to N) for 208/240 Vac input voltage. Refer to Section 9.0 - SM-Plus™ POWER WIRING DIAGRAM.
If the drive is rated for single and three phase input, 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, or T3. 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 ratings: 300 V for 120, 208 and 240 Vac systems, and 600 V for 400, 480, and 590 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.
13
10.0CONTROL WIRING
10.1CONTROL 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 6mm) of insulation for control wiring, and torque the 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.
10.2TB-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.
10.3SURGE 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.
10.4START/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 - SM-Plus™ CONTROL WIRING DIAGRAMS.
10.5SPEED 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. |

13C (Parameter 10, 11, or 12) |
may be programmed as the input select for the desired |
analog input signal. When that TB-13 terminal is then closed to TB-2, the drive will follow the selected analog speed reference input.
If an analog speed reference input is not selected on the terminal strip using TB-13A, 13B, or 13C, speed control will default to STANDARD mode, which is governed by the setting of Parameter 05 - STANDARD SPEED SOURCE. The STANDARD SPEED SOURCE can be the ▲ and ▼ buttons on the front of the drive, PRESET SPEED #1(Parameter 31), a 0-10 VDC signal, or a 4-20 mA signal.
0-10 VDC and 4-20 mA INPUT SIGNALS
TB-13A, TB-13B, and TB-13C can all be programmed to select a 0-10 VDC or 4-20 mA analog speed reference input.
PRESET SPEEDS
TB-13A can be programmed to select PRESET SPEED #1, TB-13B to select PRESET SPEED #2, and TB-13C to select PRESET SPEED #3. There are a total of seven preset speeds, which are activated by different combinations of contact closures between TB-13A, 13B, 13C and TB-2. Refer to Parameters 31-37 in Section 15.0 - DESCRIPTION OF PARAMETERS.
JOG
TB-13B can be programmed to select either JOG FORWARD or JOG REVERSE. The Jog speed is set by PRESET SPEED #2. Close TB-13B to TB-2 to JOG, and open the contact to STOP.
When operating in JOG mode, the STOP terminal (TB-1) and the STOP key (on the optional remote keypad) WILL NOT stop the drive. To stop the drive, remove the JOG command.
JOG REVERSE will operate the drive in reverse rotation even if ROTATION DIRECTION (Parameter 17) is set to FORWARD ONLY.
NOTE: If the drive is commanded to JOG while running, the drive will enter JOG mode and run at PRESET SPEED #2. When the JOG command is removed, the drive will STOP.
MOTOR OPERATED POT (MOP) / FLOATING POINT CONTROL
TB-13B and TB-13C are used for this function, which controls the drive speed using contacts wired to the terminal strip. Program TB-13B for DECREASE FREQ (05), and program TB-13C for INCREASE FREQ (05). Closing TB-13B to TB-2 will cause the speed setpoint to decrease until the contact is opened. Closing TB-13C to TB-2 will cause the speed setpoint to increase until the contact is opened. The INCREASE FREQ function will only operate while the drive is running.
15
NOTE: If TB-13A, TB-13B, and TB-13C are all programmed to select speed references, and two or three of the terminals are closed to TB-2, the higher terminal has priority and will override the others. For example, if TB-13A is programmed to select 0-10 VDC, and TB-13C is programmed to select PRESET SPEED #3, closing both terminals to TB-2 will cause the drive to respond to PRESET SPEED #3, because TB-13C overrides TB-13A.
The exception to this is the MOP function, which requires the use of TB-13B and TB-13C. This leaves TB-13A to be used for some other function. If TB-13A is programmed for a speed reference, and TB-13A is closed to TB-2, TB-13A will override the MOP function.
10.7ANALOG OUTPUT SIGNALS
Terminal TB-30 can provide a 0-10 VDC or a 2-10 VDC signal proportional to output frequency or load, and TB-31 can provide the same signals proportional to load only. The 2-10 VDC signal can be converted to a 4-20 mA signal using a resistor in series with the signal such that the total load resistance is 500 Ohms. Refer to Parameters 08 and 09 in Section 15.0 - DESCRIPTION OF PARAMETERS.
NOTE: These analog output signals cannot be used with “loop-powered” devices that derive power from a 4-20 mA signal.
10.8DRIVE STATUS DIGITAL OUTPUTS
There are two open-collector outputs at terminals TB-14 and TB-15. The open-collector circuits are cur- rent-sinking types rated at 30 VDC and 50 mA maximum.
The open-collector outputs can be programmed to indicate any of the following: RUN, FAULT, INVERSE FAULT, FAULT LOCKOUT, AT SPEED, ABOVE PRESET SPEED #3, CURRENT LIMIT, AUTO SPEED MODE, and REVERSE. Refer to Parameters 06 and 13 in Section 15.0 - DESCRIPTION OF PARAMETERS.
