particles.

Disposal

Please contact your state environmental agency for details on disposal of electrical components

and packaging in your particular area. Never dispose of electrical components by incineration.

TOSHIBA

CAUTION

Installation Safety Precautions

1) Always ground the unit to prevent electrical shock and to help reduce

electrical noise. A separate ground cable should be run inside the conduit

with the input, output, and control power cables (See Grounding page 17).

THE METAL OF CONDUIT IS NOT AN ACCEPTABLE GROUND.

2) Only qualified personnel should install this equipment (see General Safety Instructions on

page 5).

3) Installation of drive systems should conform as a minimum, to the 1996 NEC National Electrical

Code Article 110 "Requirements For Electrical Installations", to all regulations of the Occupational

Safety and Health Administration, and to any other applicable national, regional or industry codes

and standards.

4) Install in a secure and upright position in a well ventilated location that is out of direct sunlight.

The ambient temperature should be between -10° C and 40° C.

5) Allow a clearance space of 4 inches (20 cm) for the top and bottom and 2 inches (5 cm) on both

sides. This space will insure adequate ventilation. Do not obstruct any of the ventilation openings.

6) Avoid installation in areas where vibration, heat, humidity, dust, fibers, steel particles, explosive

mists, gasses or sources of electrical noise are present.

7) Adequate working space and illumination must be provided for adjustment, inspection and

maintenance of the drive (see 1996 NEC Article 110-16).

8) A noncombustible insulating floor or mat should be provided in the area immediately surrounding

the electrical system where maintenance is required.

9) Use lockout/tagout procedures on branch circuit disconnect before drive installation.

10) Connect three phase power of the correct voltage to input terminals L1, L2, L3 (R, S, T) and connect

3- phase power from output terminals T1, T2, T3 (U, V, W) to a motor of the correct voltage and type

for the application. Size the branch circuit conductors in accordance with Selection of Main Circuit

Wiring Equipment and Standard Cable Sizes Page 16.

11) If conductors of a smaller than recommended size are used in parallel to share current then the

conductors should be kept together in sets i.e. U1, V1, W1 in one conduit and U2, V2, W2 in another

(see 1996 NEC Article 300-20 and Article 310-4). National and local electrical codes should be

checked for possible cable derating factors if more than three power conductors are run in the same

conduit (see 1996 NEC Article 310 adjustment factors on page 70-196).

12) Install a molded case circuit breaker (MCCB) between the power source and the drive. Size the

MCCB to clear the available fault current of the power source (see 1996 NEC Article 430 Article 102

through Article 111).

TOSHIBA

Installation Safety Precautions (cont'd)

13) Use separate metal conduits for routing the input power, output power, and control circuits.

14) If the factory provided door or NEMA 1 enclosure is removed from the drive, then, before operating,

it must be provided with an alternate enclosure of NEMA 1 minimum rating.

15) Do not connect control circuit terminal block return connections marked CC to inverter earth ground

terminals marked GND(E). See Standard Power Connection Diagrams on page 18 and Typical

Control Wire Connection Diagrams on page 20 for locations.

16) If a secondary Magnetic Contactor (MC) is used between the inverter output and the load, it should

be interlocked so the ST-CC terminals are disconnected before the output contactor is opened. If

the output contactor is used for bypass operation, it must also be interlocked so that commercial

power is never applied to the inverter output terminals (U,V,W).

17) Power factor improvement capacitors or surge absorbers must not be installed on the drive's output.

18) For those applications requiring extended ASD to motor cable lengths exceeding the chart

recommendation shown on page 17, a output voltage filter should be added.

CAUTION

TOSHIBA

Operating Safety Precautions

1) Do not touch any internal part with power applied to the drive;

first remove the power supply from the drive and wait until charge

LED (see page 24 for location) is no longer illuminated. Charged capacitors can present a

hazard even if source power is removed from the drive.

2) DO NOT OPERATE THIS UNIT WITH ITS CABINET DOOR OPEN.

3) Do not touch the heatsink while unit is in operation. Serious burns could result.

4) Only properly trained and qualified personnel should be allowed to service or have access to

the adjustments and operation of this equipment. They should be familiar with operating motor

drives and with the driven machinery. See page 5.

5) Follow all warnings and precautions and use care not to exceed equipment ratings.

6) Do not power up the drive before completely reviewing this manual.

7) The input voltage must be within +/-10% of the specified input voltage. Voltages outside of this

permissible tolerance range may cause internal protection devices to turn on or can cause damage

to the drive. Also, the input frequency should be within +/-2 Hz of the specified input frequency.

8) Do not use this drive with a motor whose rated input is greater than the rated drive output.

9) Do not apply commercial power to the drive output terminals T1 (U), T2 (V), or T3 (W) even if the

source power is off. Disconnect the drive from the motor before applying bypass voltage to the motor.

10) Interface problems can occur when this drive is used in conjunction with some types of process

controllers. Signal isolation may be required to prevent controller and/or drive malfunction

(contact Toshiba or the process controller manufacturer for additional information about compatibility

and signal isolation).

11) Do not open and then re-close a secondary magnetic contactor (MC) between the drive and the load

unless the drive is OFF (output frequency has dropped to zero) and the motor is not rotating. Abrupt

re-application of the load while drive is on or while motor is rotating can cause drive damage.

12) Use caution when setting output frequency. Overspeeding a motor can decrease its torque-

developing ability and can result in damage to the motor and/or driven equipment and can

result in serious personal injury.

13) Use caution when setting the acceleration and deceleration time. Unnecessarily short times can

cause tripping of the drive and mechanical stress to loads.

14) If the drive produces smoke, odor or abnormal noises, turn off input power immediately and request

service.

15) If the drive will be inactive for a long period of time, turn off the input power.

DANGER

CAUTION

TOSHIBA

Start-Up and Test

Prior to releasing an electrical drive system for regular operation after installation, the system should be

given a start-up test by qualified personnel. This assures correct operation of the equipment for reasons

of reliable and safe performance. It is important to make arrangements for such a check and that time is

allowed for it.

When power is applied for the first time, the drive automatically starts up in the frequency monitor

function of standard monitor mode with the 'default' parameters set as shown in the "FACTORY

SETTING" column of the parameter tables starting on page 36. If these settings are not optimal for

the application, program the desired settings before initiating a run. The drive can be operated with no

motor connected. Operation with no motor connected or use with a small trial motor is recommended

for initial adjustment or for learning to adjust and operate the drive.

Maintenance

1) Use power lockout/tagout procedures on the disconnecting means in accordance

with applicable electrical codes (see 1996 NEC Article 430-101) before performing any

drive maintenance.

2) Periodically check the operating drive for cleanliness.

3) Do not use liquid cleaning agents.

4) Keep the heatsink free of dust and debris.

5) Periodically check electrical connections for tightness (with power off,

locked out, and with charge LED extinguished (see page 24 for location)).

CAUTION

Confirmation of Wiring

Make the following final checks before applying power to the unit:

1) Confirm that source power is connected to terminals L1, L2, L3 (R, S, T).

Connection of incoming source power to any other terminals will damage the drive.

2) The 3-phase source power should be within the correct voltage and frequency tolerances.

3) The motor leads must be connected to terminals T1, T2, T3 (U, V, W).

4) Make sure there are no short circuits or inadvertent grounds and tighten any loose connector

terminal screws.

** Typical cable size (AWG)

TOSHIBA

*A customer supplied disconnect means must be provided in the motor branch circuit which

supplies power to the drive. It can be separate for use with customer supplied fuses or it can

be an integral part of a customer supplied 3-pole circuit breaker (see 1996 NEC Article 430-103

through 430-113). All drives in this series are rated for output short circuit fault currents of

200,000A. The selection of MCCB (molded case circuit breaker) for this table is in accordance

with 1996 NEC Article 430-51, 430-52, 430-152, and 240-6.

** Wire sizing is based upon NEC table 310-16 or CEC Table 2 using 75 deg C cable, an ambient

of 30 deg C, cable runs for less than 300 FT., and copper wiring for not more than three

conductors in raceway or cable or earth (directly buried). The customer should consult the NEC

or CEC wire Tables for his own particular application and wire sizing.

*** Use two parallel conductors instead of a single conductor (this will allow for the proper wire

bending radius within the cabinet). Use separate conduits for routing parallel conductors.

This prevents the need for conductor derating (see note 3 page 17).

Turn off power to the drive before making any wiring

changes to the analog output circuits.

CAUTION

Use separate conduits for routing incoming power, power

to motor, and control conductors. Use no more than three

power conductors and a ground conductor per conduit.

Selection of Main Circuit Wiring Equipment and Standard Cable Sizes (cont'd)

Notes:

1.) Contacts used to connect drive terminals should be capable of switching low current

signals (i.e. 5 mA).

2.) The drive has internal motor overload protection which has been functionally certified by

Underwriters Laboratories Inc. and no additional external motor overload protection is required

when used to drive a single motor load (see 1996 NEC Article 430-32 and 430-39).

3.) When wiring with parallel conductors, the conductors should be kept together in phase sets to

avoid heating the surrounding metal by induction. Install U1, V1, W1 conductors in one conduit

and parallel conductors U2, V2, W2 in another conduit. The ground conductor must be run in the

same conduit. See 1996 NEC Article 300-20(a), 310-4, 310-5. Size the grounding conductor in

accordance with 1996 NEC Table 250-95.

4) Twisted pair wires should be used for external meters connected to AM and FM terminals.

5) For multiple motor applications, a thermal-magnetic circuit breaker must be installed between

the drive and each motor (even though the drive has has built-in overload protection). The thermal

circuit is for overload sensing and the magnetic coil is for abnormal conditions such as short circuits.

Select the MCCB (molded case circuit breaker) in accordance with 1996 NEC Article 430-51 through

430-53, 430-152, and 240-6.

TOSHIBA

Grounding

The drive must be grounded in accordance with Article 250 of the National Electrical Code or Section 10

of the Canadian Electrical Code, Part I and the grounding conductor should be sized in accordance with

1996 NEC Table 250-95 or CEC, Part I Table 16. See Installation Safety Precautions notes 7 and 14.

Motor Selection

1) Exceeding the peak voltage rating or the rise time allowable of the motor insulation system will

reduce the life expectancy. To insure good motor insulation life, consult with the motor supplier to

determine motor insulation ratings and allowable maximum output lead distance. Long lead lengths

between the motor and the drive may require filters to be added to the drive output.

2) Bearing Considerations:

Motors operating from adjustable speed drive power sources tend to operate at higher

temperatures which may increase the need for more frequent lubrication cycles.
