Cause Severe Injury Or Loss Of Life.
DANGER
!
When using an ASD output disconnect, the ASD and the motor MUST be stopped before the
disconnect is either opened or closed. Closing the output disconnect while the 3-phase output
of the ASD is active may result in equipment damage or injury to personnel.
De-energize and lockout/
tagout the main power,
control power, and
instrumentation connections
before connecting or
disconnecting the power
wiring to the equipment or
opening the enclosure door.
Connect the 3-phase input
power to the ASD to
terminals R/L1, S/L2, and T/L3. Connect the 3-phase output power from terminals U/T1, V/T2,
and W/T3 to the motor. Ensure that all wiring is performed in accordance with national, state,
and local electrical codes.
Install a circuit disconnecting device and branch circuit protection in accordance with the fault
current settings of the ASD and the 2008 NEC Article 430.
For 2-Wire Control and 3-Wire Control open the enclosure door to gain access to the Terminal
Board and continue below.
2-Wire Control
Install a switch as described below from the F and/or R terminals to the CC terminals. Close or
reattach the enclosure door.
1 — Normally open switch that will be used to provide the forward run command (Set to
Forward).
2 — Normally open switch that will be used to provide the reverse run command (Set to
Reverse).
3-Wire Control
Install momentary push buttons as described below from the F and/or R terminals to the CC
terminal. Close or reattach the enclosure door.
1 — Normally open momentary push button that will be used to provide the forward run
command (Set to Forward).
2 — Normally open momentary push button that will be used to provide the reverse run
command (Set to Reverse).
3 — Normally closed momentary push button that will be used to hold the output frequency
upon termination of the run command (Set to Hold: F116 = 49 (Hold, N.O.).
Before turning on the ASD ensure that:
The enclosure door is closed or reattached, and secure. Terminals R/L1, S/L2, and T/L3 are
connected to the input power and terminals U/T1, V/T2, and W/T3 are connected to the motor.
The 3-phase input voltage is as specified and there are no shorts and all grounds are secure.

1. Receipt & Identification
Inspect the equipment for damage that may have occurred during
shipping.
DO NOT install or energize equipment that has been damaged.
Ensure that the rated capacity and model number on the nameplate
conform to order specifications.
Use proper lifting techniques when moving the S11 ASD.
Contact your Toshiba Sales Representative to report discrepancies or
for assistance if required.
2. Mounting
Only qualified personnel should install this equipment.
The installation of the equipment should conform to the 2008 National Electrical Code (NEC)
Article 110, OSHA, as well as any other applicable national, regional, or industry codes and
standards.
Installation practices shall conform to the latest revision of the NFPA 70E Electrical Safety
Requirements for Employee Workplace.
It is the responsibility of the S11 ASD installer/maintenance personnel to ensure that the unit is
installed in an enclosure that will protect personnel against electric shock.
Location
Select a mounting location that is easily accessible and has adequate working space. Proper
illumination is required for making inspections, adjustments, and performing equipment
maintenance.
DO NOT mount the S11 ASD in a location that would produce catastrophic results if it were to
fall from its mounting location (equipment damage and/or injury to personnel).
Avoid installation in direct sunlight or in areas where vibration, heat, humidity, dust, fibers,
metal particles, explosive/corrosive mists or gases, sources of electrical noise are present, or
where it would be exposed to harmful liquids, solvents, or other fluids.
Temperature
The ambient operating temperature rating is 14 to 122 F (-10 to 50 C).
Ventilation
Install the unit in an upright position and in a well-ventilated area.
When installing adjacent ASDs horizontally, Toshiba recommends at least 5 cm of space
between units. However, if the top cover is removed from each ASD then horizontally
mounted ASDs may be installed side-by-side with no space in-between the adjacent ASDs.
For all S11 ASDs, a minimum of 10 cm of space is required above and below adjacent units.
Lead Length
The table below lists the recommended maximum lead lengths for the listed motor voltages.
Lead lengths from the ASD to the motor in excess of those listed below may require filters to
be added to the output of the ASD. Excessive lead lengths may adversely affect the
performance of the motor. Exceeding the peak voltage rating or the allowable thermal rise
time of the motor insulation will reduce the life expectancy of the motor.
Contact your Toshiba Sales Representative for application assistance when using lead lengths
in excess of those listed.
For enclosure and mounting hole dimensions consult the S11 ASD Instruction Manual .
