G7 ASD Quick Start Guide 11

Installation and Connections

The G7 True Torque Control2 Adjustable Speed Drive may be set up initially by performing a few
simple configuration settings. To operate properly , the ASD must be securely mounted and connected to
a power source (3-phase AC inpu t at the L1/R, L2/S, and L3/T terminals). The control terminals of the
ASD may be used by connecting the terminals of the Control Terminal Strip to the proper sensors or
signal input sources (see the section titled

Note: The optional ASD-Multicom boards may be used to expand the I/O functionality of

the ASD. See the section titled G7 Optional Devices in the G7 ASD Operation
Manual for further information on the availab le options.

The output terminals of the ASD (T1/U, T2/V, and T3/W) must be connected to the motor that is to be
controlled (see

As a minimum, the installation of the ASD shall conform to Article 110 of the 2005 NEC, the
Occupational Safety and Health Administration requirements, and to any other local and regional
industry codes and standards.

Figure 15 on pg. 19).

I/O and Control on pg. 17).

Upon initial system powerup, the Startup Wizard starts automatically . The Startup Wizard assists the
user with the initial configuration of the G7 True Torque Control
section titled

Initial Setup on pg. 22 for additional information on the Startup Wizard.

Installation Notes

When a brake-equipped motor is connected to the ASD, it is possible that the brake may not release at
startup because of insufficient voltage. To avoid this, Do Not connect the brake or the brake contactor to
the output of the ASD.

If an output contactor is u sed for bypass operation, it must be interlocked such that comm ercial power is
never applied to the output terminals of the ASD (T1/U, T2/V, or T3/W).

If a secondary magnetic contactor (MC) i s u sed bet ween the output of the ASD and the mot or, it should
be interlocked such that the ST – CC connection is disconnected before the output contactor is opened.

Do Not open and then close a secondary magnetic contactor between the ASD and the motor unless the
ASD is off and the motor is not rotating.

Note: Re-application of power via a secondary contact while the ASD is on or while the

motor is still turning may cause ASD damage.

On some devices the ST-to-CC connection i s f urther enhanced by the operation of the MS1 AUX relay
circuit. The MS1 AUX relay circuit is normally open and closes the ST-to-CC connection (via ST1)
only after normal system power is available. The MS1 AUX relay circuit prohibits the ST-to-CC
connection in the event that the MS1 contactor fails to close during start up or if MS1 opens while the
ASD is running. For the 230 volt ASD this feature is available on the 30 HP system, on the 460 volt
ASD this feature is available on the 75 HP and above systems, and on the 600 volt ASD it is available
on the 60 HP and above systems.

The ASD input voltage should remain within 10% of the specified input voltage range. Input voltag e s

approaching the upper or lower limit settings may require that the overvoltage and undervoltage stal l
protection level parameter be adjusted. Voltages outside of the permissible tolerance should be avoided.

The freque ncy of the in put power should be ±2 Hz of the specified input frequency.
Do not use an ASD with a motor that has a power rating that is higher than the rated output of the ASD.
The ASD is designed to operate NEMA B motors. Consult with your sales representative before using

the ASD for special applications such as with an explosion-proof motor or applications with a piston
load.

Do Not apply commercial power to the output terminals T1/U, T2/V, or T3/W.
Disconnect the ASD from the motor before megging or applying a bypass voltage to the motor.
Interface problems may occur when an ASD is used in conjunction with some types of process

controllers. Signal isolation may be required to prevent controller and/or ASD malfunction (contact
your Toshiba sales representative or the process contr oller manufacturer for additional information
about compatibility and signal isolation).

Use caution when setting the output frequency. Over speeding a motor decreases its ability to deliver
torque and may result in damage to the motor and/or the driven equipment.

All G7 ASDs are equipped with internal DC bus fuses. However, not all G7 ASDs are equipped with
internal primary power input fuses (HP dependent). When connecting two or more drives that have no
internal fuse to the same power line as shown in
breaking configuration that will ensure that if a short circuit occurs in ASD 1, only MCCB2 trips, not
MCCB1. If it is not feasible to use this configuration, insert a fuse between MCCB2 and ASD 1.

Figure 3, it will be necessary to select a circuit-

Mounting the ASD

Install the unit securely in a well ventilated area that is out of direct sunlight using the mounting holes
on the rear of the ASD.

The ambient temperature rating for the G7 ASD is from 14 to 104° F (-10 to 40° C). The process of
converting AC to DC, and then back to AC produces heat. During normal ASD op eration, up to 5% of
the input energy to the ASD may be dissipated as heat. If installing the ASD in a cabinet, ensure that
there is adequate ventilation.

G7 ASD Quick Start Guide 13

CAUTION

Do Not operate the ASD with the enclosure door open.
When installing multiple ASDs, ensure that there is a clearance space of at least 8 inches (20 cm) from

the top and the bottom of adjacent units. There should be at least 2 inches (5 cm) on either side of
adjacent units. For the models below 50 HP the top and bottom clearance specifications may be reduced
to 4 inches (10 cm). This space ensures that adequate ventilation is provided (see the G7 ASD

Operation Manual for additional information on mounting space requirements).
Note: Ensure that the ventilation openings are not obstructed.

ASDs produce high-frequency noise — steps must be taken during installation to avoid the negative
effects of noise. Listed below are some examples of measures that will help to combat noise problems.

• Separate the input and output power conductors of the main circuit. Do not install the input and
output wires in the same duct or in parallel with each other, and do not bind them together.

• Do not install the input or output power conductors of the main circuit and the wires of the control
circuit in the same duct or in parallel with each other, and do not bind them together.

• Use shielded wires or twisted wires for the control circuits.

• Ensure that the grounding terminals (G/E) of the ASD are securely connected to ground.

• Connect a surge suppressor to every electromagnetic contactor and every relay installed near the
ASD.

• Install noise filters as required.

Connecting the ASD

DANGER

Refer to the section titled Installation Precautions on pg. 4 and the section titled Lead Length

Specifications on pg. 16 before attempting to connect the ASD and the motor to electrical power.

System Grounding

Proper grounding helps to prevent electrical shock and to reduce electrical noise. The ASD is designed
to be grounded in accordance with Article 250 of the 2005 NEC or Section 10/Part One of the
Canadian Electrical Code (CEC).

The grounding conductor shall be sized in accordance with Article 250-122 of the NEC or Part One-

Table

6 of the CEC.

Note: The metal of conduit is not an acceptable ground.

The input, output, and control lines of the system shall be run in separate metal conduits and each shall
have its own ground conductor.

Power Connections

DANGER

L1/R, L2/S, and L3/T are the 3-phase input supply terminals for the ASD. The ASD may be operated
from a single-phase supply. When operating using a single-phase supply, use the L1 and L3 terminals.
