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 termination resistors (390Ω, 220Ω, 390Ω) in the
optional board connected to the last equipment integrated into 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.

SD500 –PROFIBUS
POWER ELECTRONICS

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 even 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.
SAFETY
A Before operating the inverter, read this manual thoroughly to
gain and understanding of the unit. If any doubt exists then
please contact POWER ELECTRONICS, (902 40 20 70 / +34 96
136 65 57) or your nearest agent.
Wear safety glasses when operating the inverter with power
applied and the front cover is removed.
Handle the inverter with care according to its weight.
Install the inverter according to the instructions within this
manual.
Do not place heavy objects on the inverter.
Ensure that the mounting orientation is correct.
Do not drop the inverter or subject it to impact.
The SD500 inverters contain static sensitive printed circuits
boards. Use static safety procedures when handling these
boards.

SAFETY INSTRUCTIONS
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 SD450 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.
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.

INTRODUCTION
1. INTRODUCTION
1.1. Description of Profibus Optional Board
The optional board for Profibus communication allows SD450 drive to
connect it to a Profibus network. Thanks to this optional board:
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.
Compatible with PC System, PLC and any controllers is available,
making Factory Automation more easily.

3. INSTALLATION AND CONNECTION
3.1. Installation of Profibus Optional Board
The Profibus optional board is connected to the SD500 Series
inverters of Power Electronics directly (through a connector) to
integrate the equipment into a Profibus communications network.
Therefore, it is necessary to use one Profibus optional board for any
equipment to connect it to the network.
CAUTION
Motor controllers of Power Electronics operate with a high electric
energy.
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 Profibus optional board. Otherwise, you may get personal
injuries or an accident could occur.
