Usage Precautions
•Please use the communications interface only when the ambient temperature of the
inverter unit into which the interface is installed is within the following specified
temperature limits:
Operation:-10 ∼+40°C (+14 ∼+104°F)
Storage:-25 ∼+65°C (-13 ∼+149°F)
•Avoid installation locations that may be subjected to large shocks or vibrations.
•Avoid installation locations that may be subjected to rapid changes in temperature or
humidity.
Operating Environment
•Do not touch charged parts such as the terminal block while the inverter’s CHARGE
lamp is lit. A charge will still be present in the inverter unit’s internal electrolytic
capacitors, and therefore touching these areas may result in an electrical shock.
Always turn all inverter input power supplies OFF, and wait at least 5 minutes after the
CHARGE lamp has gone out before wiring the communication cables or motor wiring.
•When installing the communications interface into the inverter and making wiring
connections, make certain that no clippings or wiring leads that could cause device
failure fall into the inverter or onto electronic components.
•Proper ground connections are vital for both safety and signal reliability reasons. For
proper grounding procedures, please refer to the section in this manual pertaining to
grounding (section 2).
•Route the communication cables separate from the inverter input/output power wiring.
•To avoid the possibility of electric shock due to leakage currents, always ground the
inverter unit’s E/GND terminal and the motor. To avoid misoperation, do not connect the
communication interface’s SHIELD terminal to either of the above-mentioned grounds or
any other power ground.
Installation •Wiring
•The inverter’s EEPROM has a life span of 10,000 write cycles. Do not write to BO #9,
BO #10, or AO #2 ∼AO #13 more than 10,000 times.
•Do not touch or insert a rod or any other item into the inverter while power is applied, as
this may lead to electrical shock or inverter damage.
•Commission the disposal of the communications interface to a specialist.
•Do not assign the same address to more than one inverter in the same network.
•Individual device addresses can be set from 1 ∼255. Address 0 is invalid and will cause
the inverter to trip “Err8” (communication interface card error).
•When the inverter’s control power supply is turned on, the inverter performs initialization
functions for approximately 3 seconds, during which communications capabilities are
disabled. Communications capabilities will also be disabled for approximately 3 seconds
after momentary control power supply outages or inverter resets.

1. Interface Board Installation / Removal
The EIII inverter does not require any additional hardware components other than the
Metasys N2 communications interface board in order to connect to and communicate
with the N2 network. This portion of the manual will detail the procedure used to install
and remove the interface board. If at any time you experience problems during the
installation / removal process, please call Toshiba International Corporation for
assistance.
1.1 Installation Procedure
Installation of the Metasys N2 interface board into a EIII inverter should only be
performed by a qualified technician familiar with the maintenance and operation of the
EIII. To install the interface board, perform the following procedure:
1. CAUTION! Verify that all input power sources to the inverter have
been turned OFF and are locked and tagged out.
2. DANGER! Wait at least 5 minutes for the inverter’s electrolytic
capacitors to discharge before proceeding to the next step. Do not touch any
internal parts with power applied to the inverter, or for at least 5 minutes
after power to the inverter has been removed. A hazard exists temporarily
for electrical shock even if the source power has been removed.
3. Remove the inverter’s cover (open the door on units with hinged doors).
Verify that the CHARGE LED has gone out before continuing the installation
process.
4. Loosen the 4 screws attaching the EIII’s operation panel support bracket to the
control board support bracket, and then remove the operation panel and support
bracket as a unit (refer to Figure 1).
5. Install the 4 nylon standoffs into the holes provided in the control board support
bracket (refer to Figure 2).
6. Install the N2 network cable through the access holes at the bottom of the inverter
and route the cable in order to make connections to the interface board connector
(TB1). Take care to not route the cable near any sharp edges or in positions
where it may be pinched.

7. CAUTION! The Metasys N2 interface board is a static-sensitive device.
Standard electrostatic-sensitive component handling precautions should be
observed. Connect the N2 bus cable to the interface board connector (TB1). For
more information on making connections to the N2 bus, refer to section 6.1 on
page 13.
CAUTION! Extremely high voltages exist in the area near the interface board
and connector (TB1) once installed in the EIII. Ensure that no stray wires (such as
the shield on the N2 bus cable) come into contact with any internal inverter
components. Also ensure that the N2 bus cable is not routed in such a manner
that it may come into contact with high-voltage inverter components, or inverter
components that may heat up during operation and damage the cable insulation.
8. Install the interface board into the inverter by carefully aligning the 4 nylon standoffs
with the 4 mounting holes provided in the interface board. Ensure that connector
CN5A on the back side of the interface board is aligned with connector CN5 on the
front side of the control board.
9. Press the interface board firmly onto the standoffs and connector CN5 until the
standoff retaining tabs lock. Ensure that CN5 and CN5A are thoroughly
interlocked.
10. Carefully re-install the operation panel and support bracket and tighten the 4
screws that attach the operation panel support bracket to the control board
support bracket.
11. Reinstall the inverter’s cover (close and latch the door on units with hinged doors).
DANGER! Do not operate the unit with the cover off /
cabinet door open.
12. Turn all power sources to the inverter unit ON, and verify that the inverter functions
properly. If the inverter unit does not appear to power up, or does not function
properly, immediately turn power OFF. Repeat steps 1 ∼3 to remove all power
from the inverter. Then, verify all connections. Contact Toshiba International
Corporation for assistance if the problem persists.
