SAFETY INSTRUCTIONS
IMPORTANT!
Safety instructions showed in this manual are useful to teach user
how to use the product in a correct and safety way with the purpose
of preventing possible personal injuries or property damages.
Safety messages included here are classified as it follows:
WARNING
Be sure to take ESD (Electrostatic Discharge) protection measures
when you touch the board.
Otherwise, the optional board may get damaged due to static charges.
Implement wiring change on the optional board after checking that
the power supply is off.
Otherwise, there is a danger of connecting error and damage to the
board.
Be sure to connect correctly the optional board to the inverter.
Otherwise, there is a danger of connecting error and damage to the
board.
Be sure to install a termination resistor (120Ω, 1/4W) at the end of the
network.
Do not remove the cover while the power is applied or the unit is in
operation.
Otherwise, electric shock could occur.
Do not run the inverter with the front cover removed.
Otherwise, you may get an electric shock due to the high voltage
terminals or exposure of charged capacitors.

SAFETY INSTRUCTIONS
Do not remove the cover except for periodic inspections or wiring,
even if the input power is not applied.
Otherwise, you may access the charged circuits and get an electric shock.
Wiring and periodic inspections should be performed at least 10
minutes after disconnecting the input power and after checking the
DC Link voltage is discharged with a meter (below 30VDC).
Otherwise, you may get an electric shock.
Operate the switches with dry hands.
Otherwise, you may get an electric shock.
Do not use cables with damaged insulation.
Otherwise, you may get an electric shock.
Do not subject the cables to the abrasions, excessive stress, heavy
loads or pinching.
Otherwise, you may get an electric shock.
CAUTION
Install the inverter on a non-flammable surface. Do not place
flammable material nearby.
Otherwise, fire could occur.
Disconnect the input power if the inverter gets damaged.
Otherwise, it could result in a secondary accident or fire.
After the input power is applied or removed, the inverter will remain
hot for a couple of minutes.
Touching hot parts may result in skin burns.
Do not apply power to a damaged inverter or to an inverter with parts
missing even if the installation is complete.
Otherwise, fire or accident could occur.
Do not allow lint, paper, wood chips, dust, metallic chips or other
foreign matter into the drive.
Otherwise, fire or accident could occur.

WARNINGS
RECEPTION
Material of Power Electronics is carefully tested and perfectly
packed before leaving the factory.
In the event of transport damage, please ensure that you notify
the transport agency and POWER ELECTRONICS: 902 40 20 70
(International [phone]) or your nearest agent, within
24hrs from receipt of the goods.
UNPACKING
Make sure received merchandise corresponds with delivery note,
models and serial numbers.
Each optional board is supplied with a technical manual.
RECYCLING
The packing of the drives must be recycled. For this reason it is
necessary to separate different materials (plastics, paper,
cardboard, wood …) and settle them in corresponding containers.
The residual parts of electrical devices must be collected in a
selective manner in order to warranty the correct environmental
treatment.
CONNECTION PRECAUTIONS
To ensure correct operation of the inverter it is recommended to
use a SCREENED CABLE for the control wiring.
For EMERGENCY STOP, make sure supply circuitry is open.
Do not disconnect motor cables if input power supply remains
connected. The internal circuits of the SD700 Series will be
damaged if the incoming power is connected and applied to
output terminals (U, V, W).
It is not recommended to use a 3-wire cable for long distances.
Due to increased leakage capacitance between conductors, over-
current protective feature may operate malfunction.

SAFETY INSTRUCTIONS
Do not use power factor correction capacitors, surge
suppressors, or RFI filters on the output side of the inverter.
Doing so may damage these components.
Always check whether the DC Link LED is OFF before wiring
terminals. The charge capacitors may hold high-voltage even
after the input power is disconnected. Use caution to prevent the
possibility of personal injury.
TRIAL RUN
Verify all parameters before operating the inverter. Alteration of
parameters may be required depending on application and load.
Always apply voltage and current signals to each terminal that
are within levels indicated within this manual. Otherwise, damage
to the optional board may result.
EARTH CONNECTION
The inverter is a high frequency switching device, and leakage
current may flow. Ground the inverter to avoid electrical shock.
Use caution to prevent the possibility of personal injury.
Connect only to the dedicated ground terminal of the inverter. Do
not use the case or the chassis screw for grounding.
When installing, grounding wire should be connected first and
removed last.
The earth cable must have a minimal cross sectional area that
meets local country electrical regulations.
Motor ground must be connected to the drive ground terminal
and not to the installation’s ground. We recommend that the
section of the ground connection cable should be equal or higher
than the active conductor.
Installation ground must be connected to the inverter ground
terminal.

1. DESCRIPTION
The Optical Fiber communication board permits the SD700 series
communicate through Fiber Optic hardware.
Communication without noise.
Inverter can be controlled and monitored by PLC sequence
program or any master module.
Multiple inverters can be connected to one communication cable
with simple and easy installation, saving wiring, maintenance cost
and time.
The SD700 Standard communication protocol is Modbus-RTU, so the
Modbus address specified in the Software and Programming manual
are valid. Thanks to this optional board:

3. INSTALLATION AND CONNECTION
3.1. Installation
The Optical Fiber communication board is designed for the SD700
series. It is directly connected in the connector J102 of the control
cardboard of the inverter. This cardboard provides a robust and
economic communication hardware Optical fiber solution, avoiding
external gateways.
Install the cardboard according to the mounting image. Make sure to
install correctly the connectors and the fastening system.
CAUTION
Motor controllers of Power Electronics operate with AC and DC high
voltage.
Make sure the power supply has been disconnected and wait for at least
10 minutes to guarantee that DC Link voltage is discharged, before
installing the Optical fiber board. Otherwise, you may get personal injuries
or an accident could occur.

3.3. Master Slave Connection
There are two ways to connect VFDs between them, closed loop and
open loop. In the case of closed loop, master knows that the
transmission has been received by all slaves. In the case of open loop,
master don’t receive slave feedback, the time must be set to “0”in the
group [G4.6.5].

Once the board has been connected to the inverter, it can be
configured by using the SD700 graphic or alphanumeric display.
Consult Power Electronics for updated Software and Programming
manual and Software versions.
Firstly it is necessary to configure the communication and baud rate
control that will enable the optical fiber specific subgroup G4.6.

The Start order of the master
will be sent to the FIBER
option in the groups G4.1.1
and G4.1.2. It means that if we
select the fiber option in the
control mode while the master
has a Start order, the slave
will start.

RUN
The RUN status of the master
will be sent to the FIBER
option in G4.1.1 and G4.1.2.
When the fiber option is
selected in a control mode and
the master is in RUN, the
slave will start and won‟t stop
till the RUN has been
disappeared of the master.
