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.

All safety information given in these Operating Instructions has the same layout:

DANGER! Warns of impending danger.

WARNING! Warns of potential, very hazardous situations.

STOP! Warns of potential damage to material and equipment.

Consequences if disregarded: Death or severe injuries.

Consequences if disregarded: Damage to the controller/drive or its environment.

If you observe it, handling the controller/drive system is made easier.

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.

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

Lenze 13466147 EDBSM01 v19 EN 5

1 Safety Information

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 crosssections, fuses, protective earth [PE] connection). While this document does make recommendations in regards to these items, national and local codes must be adhered to.

Integral solid state protection does not provide branch circuit protection. Branch circuit protection must be provided in accordance with the National Electrical Code and any additional local codes. The use of fuses or circuit breakers is the only approved means for branch circuit protection.

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, OEM and/or integrator to ensure that the drive is conﬁgured for safe operation.

3 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 Lenze Americas 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 2.4, 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.

3.1 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.

3.2 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 4.4, 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.

3.2.1 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 4.4, Description of Parameters.

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

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.

• Per UL Requirements, use a fuse (not a circuit breaker) for 240VAC drives requiring >40A protection and for 480 VAC & 600 VAC drives requiring >32A protection. Additionally, use a fuse (not a circuit breaker) for following models: SM275 and SM 2100.

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

3.2.4 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: The 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

Installation: Shielded cable must be used for all control and power cables and exposed wiring must be kept as short as possible.

3.3 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.

3.3.1 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 3.4, 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.
