If the labels are damaged or if additional labels are required, contact your Toshiba sales representative for additional labels. Labels attached to the equipment are there to provide useful information or to indicate an imminently hazardous situation that may result in serious injury, severe property and equipment damage, or death if the instructions are not followed.
• Have carefully read the entire operation manual. • Be familiar with the construction and function of the Q7 Flow, the equipment being driven, and the hazards involved. • Able to recognize and properly address hazards associated with the application of motor-driven equipment.
(refer to 2002 NEC Article 110-13). • Do Not mount the Q7 Flow in a location that would produce catastrophic results if it were to fall from its mounting location (equipment damage or injury). •...

Installation practices should conform to the latest revision of NFPA 70E Electrical Safety Requirements for Employee Workplaces. • It is the responsibility of the person installing the Q7 Flow or the electrical maintenance personnel to ensure that the unit is installed into an enclosure that will protect personnel against electric shock.
Please contact your Toshiba sales representative for application-specific information or for training support. • The Toshiba Q7 Flow is part of a larger system and the safe operation of the Q7 Flow will depend on observing certain precautions and performing proper system integration. •...
System Setup Requirements • When using the Q7 Flow as an integral part of a larger system, it is the responsibility of the Q7 Flow installer or maintenance personnel to ensure that there is a fail-safe in place, i.e., an arrangement designed to switch the system to a safe condition if there is a fault or failure.
• The capacitors of the Q7 Flow maintain a residual charge for a period of time after turning the off the Q7 Flow. The required time for each system typeform is indicated with a cabinet label and a Charge LED.
European market is required to comply to the European Community directive on electromagnetic compatibility (EMC). The following instructions provide a means of compliance for the Q7 Flow. A Technical Construction File (TFC) indicates the rationale used to declare compliance and is on file at Toshiba International Corporation, Houston, Texas, U.S.A.

Control Signal Isolation Interface problems may occur when the Q7 Flow is used in conjunction with some types of process controllers. Signal isolation may be required to prevent controller and/or Q7 Flow malfunctions. The Q7 Flow option, the ASD-ISO-1, provides isolation of the Control Board output circuit from the AM/...
When a brake-equipped motor is connected to the Q7 Flow, it is possible that the brake may not release at startup because of insufficient voltage. To avoid this condition, Do Not connect the brake or the brake contactor to the output of the Q7 Flow.

Power Connections DANGER L1/R, L2/S, and L3/T are the 3-phase input supply terminals for the Q7 Flow. An AC Reactor may be installed to the 3-phase input to the Q7 Flow to provide filtering of the input voltage. T1/U, T2/V, and T3/W are the output terminals of the ASD that connect to the motor. A DC Reactor may be connected across terminals PA and PO to provide additional filtering.

With the previous checks confirmed, ensure that the direction of the motor rotation in the Bypass mode and in the ASD-driven mode is consistent. Q7 Flow Installation and Operation Manual Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.ctiautomation.net - Email: info@ctiautomation.net...
This section discusses the ASD control methods and supported I/O functions. The Control Terminal Strip PCB (P/N 53750; shown on 18) of the Q7 Flow supports discrete and analog I/O functions. Table 1 lists the names, the default settings (where applicable), and the descriptions of the input and output terminals of the Control Terminal Strip PCB.

CIA/CIB — These terminals make up the Customer Interlock. The CIA-to-CIB connection is a requirement for normal Q7 Flow operation. These terminals may be connected using a jumper or used to Enable/Disable the system as a function of an event or condition that opens or closes this circuit. See the section titled Q7 Flow Theory of Operation on pg.

The Control Terminal Strip PCB (P/N 53750) serves as a monitoring and control interface for the Q7 Flow. The Control Terminal Strip PCB receives input from ancillary devices, transducers that monitor system variables, or from the user via the keypad. The Control Terminal Strip PCB also provides output signals that may be used to control ancillary devices, close a contact, notify the user, or monitor system variables.
Typical Q7 Flow Connection Diagram Three variations of the Q7 Flow system are available. The variations may include bypass circuitry, optional protection features, and/or additional filtering. The different systems are identified by the IA, IC, or IE part number suffix as shown in figures 4, 5, and 6.
System Protection The Q7 Flow has protection features that are designed to protect the ASD and the motor from overload/ overcurrent damage and from the undesirable effects of undervoltage operation. Because of the different types of overcurrent conditions that may occur (e.g., inrush current, short circuit current, extended overloads, etc.), the Q7 Flow is equipped to protect the system from start-up overcurrent and running...
