observe the items described in these manuals.
Handling in general
Danger
Never
Disassemble
- Never disassemble, modify or repair the inverter.
This can result in electric shock, fire or injury.
For repairs, contact TOSHIBA group representative.
Prohibited
- Do not remove connectors when the power is on.
This can cause electric shock.
- Do not place or insert any kind of object into the inverter (electrical wire cuttings,
rods, wires and so on).
This can result in electric shock or fire.
- Do not splash water over the inverter.
This can result in electric shock or fire.
Mandatory
- Wiring should be conducted after turning off the inverter power.
- Turn off the power immediately in case any abnormality such as smoke, smell or
unusual sounds is found.
If the inverter is continued in operation in such a state, result can be fire.
Contact TOSHIBA group representative for repairs.
Transportation and Installation
Danger
Prohibited
- Do not install or operate the inverter if it is damaged or any part is missing.
Operating the inverter in a defective condition can result in electric shock or
fire. Contact TOSHIBA group representative for repairs.
- Do not place any inflammable material near the inverter.
If a flame is emitted due to malfunction, it can result in a fire.
- Do not install in any location where the inverter could come into contact with
water or other fluids.
This can result in electric shock or fire.
Mandatory
- Inverter must be used under the environmental conditions prescribed in this
instruction manual.
Using the inverter under any other conditions can result in malfunction.
Warning
Prohibited
- Do not install the inverter in a place subject to large amounts of vibration.
That could result in the unit falling, resulting in injury.

Wiring
Danger
Mandatory
- Be sure to perform the following preparatory work before proceeding to wiring.
1) Turn off all input power to the inverter.
2) Wait for at least ten minutes and check to make sure that the charge lamp
(on the inverter and in the option unit) is no longer lit.
3) Use a circuit tester that can measure DC voltages (800VDC or more), and
check to make sure that the voltage to the DC main circuits (across PA-PC)
is 45V or less.
Failure to do this preparation could lead to electric shock.
- Tighten the terminal board screws to the specified torque.
Failure to do this could lead to fire.
Operations
Danger
Prohibited
- Do not touch inverter terminals when they are energized even if the motor is
stopped.
Touching the terminals while the power is energized can result in electric
shock.
- Do not try to clean the inverter with a damp cloth.
This can result in electric shock.
- Do not pull on the cables.
This can result in damage or erroneous operation.
Disposal of Product
Warning
Mandatory
- Dispose of the inverter as an industrial waste.
Unless it is disposed of as an industrial waste, it will become risks for human
injury.

1. Introduction
Thank you for your purchase the Toshiba "TOSVERT VF-A7/P7 Control Power Option Unit"
industrial inverter.
Using this unit, control power and main circuit power for VF-A7/P7 Series (0.4 – 22kW class)
inverters can be supplied separately. (30kW or above inverters are supplied separately as
standard) This instruction manual describes the connection method and other items of the
“Control power option unit.” Read this manual carefully before you use this unit.
This manual should be stored near the user who uses the ”Control power option unit” so that
this manual can be helpful when performing maintenance and inspection in the future.
[Here is explained the type and form of the control power option unit]
CPS 001 1 - 0
[Checking the accessories]
The control power option unit has the following accessories other than the unit itself.
Unpack the package and check the contents.
(1) Control Power Option Unit Instruction Manual (This manual) 1 copy
(E6581136)
The 70cm length cable between the inverter and the option unit can cover all of the models
(0.4 – 22kW). Cable lengths other than 70cm are not provided as standard. Please pay
attention to the installation location of this unit on occasions such as when you design the
panel.
This unit can be used for both 200V class inverters and 400V class inverters.

3. Connection method
Proceed as follows to connect the unit to the inverter. (Use the circuit explanatory drawing and
the connection explanatory drawing.)
Connection method
(1) Check to make sure all input powers to the inverter are off.
(2) Open the terminal board cover (installed with two screws) and remove the jumpered
connector mounted on the connector (CN21). (See the connection explanatory drawing for
locations of the connector for each model.)
Make sure to remove the connector while holding the connector area.
(3) Connect the connector of the control power option unit to the connector (CN21) of the
inverter main unit.
(4) Wire the cable of the control power option unit through the keyhole of the inverter’s wiring
inlet plate.
Fix the cable and do not pull on the cable carelessly.
(5) Install the control power option unit near the inverter. (Two M4 screws)
(6) Connect the control power wiring to the terminals R0 and S0 of the terminal board of the
inverter main unit. (See the connection explanatory drawing for the locations of R0 and S0
for each model.)
(7) Break the keyhole blocking nail of the inverter main unit’s terminal board cover and install
the terminal board cover with two screws.
<Note> When this jumpered connector is inserted, control power is supplied from the main
circuit power. By removing this connector, control power and main circuit power can
be supplied independently. (See the circuit explanatory drawing.)
<Note> When you conduct wiring after turning off power, wait for at least ten minutes and
check to make sure the charge lamp on the inverter is no longer lit.
Remove the connector while
pressing this part.

Turning power on
(1) Turn on the control power.
(2) LED lamp by the side of the connector (CN21) of the inverter main unit and LED lamp
inside the control power option unit light and a message appears on the monitor of the
inverter and the system is ready for setting and waiting for operation.
1) LED lamp by the side of the connector (CN21) --- lights when power is supplied to the
terminal board R0 and S0 of the
inverter main unit.
2) LED lamp inside the option unit --- lights when power is supplied inside of the option unit.
Even if control power is turned off, electrical charge
remains in the capacitor of the option unit for a while.
<Note> This control power option unit can be used for both 200V inverters and 400V
inverters.
<Note> After turning off control power supply, do not remove the connector at least for 10
minutes. This can cause electric shock.
