SAFETY INSTRUCTIONS
IMPORTANT!
Read carefully this manual to maximize the performance of the
product and to ensure its safe use.
In order to use appropriately the drive, please, follow all instructions
described in the installation manual referred to transport, installation,
electrical connection and commissioning of the equipment.
Power Electronics accepts no responsibility or liability for partial or
total damages resulting from inappropriate equipment use.
Please, pay careful attention to the following recommendations:
WARNING
Make 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.
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.
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.

SAFETY INSTRUCTIONS
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 drive on a non-flammable surface. Do not place
flammable material nearby. Otherwise, a fire could occur.
Disconnect the input power if the drive gets damaged.
Otherwise, it could result in a secondary accident or fire.
Do not allow lint, paper, wood chips, dust, metallic chips or
other foreign matter into the drive. Otherwise, a fire or
accident could occur.
The inverter becomes hot during operation. Wait until it
cools down before performing any actions.
Touching hot parts may result in skin burns.
Do not apply power to a damaged drive or to a drive with
parts missing, even if the installation is complete.
Otherwise, you may get an electric shock.

NOTICE
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 board is supplied with a technical manual.
RECYCLING
Packing of the equipment should be recycled. For this, it is necessary
to separate the different included materials (plastic, paper, cardboard,
wood, …) and deposit them in corresponding containers.
Waste products of electric and electronic devices should be
selectively collected for their correct environmental management.
SAFETY
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 / [phone]) or your nearest
agent.
Wear safety glasses when operating the inverter with power applied or
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 drives 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 drive 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.
COMMISSIONING
Follow the steps described in this manual.
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.

OPERATION PRECAUTIONS
When the Auto Restart function is enabled, keep clear of driven
equipment, as the motor will restart suddenly after a fault is reset.
The “STOP / RESET” key on the keypad is active only if the
appropriate function setting has been made. For this reason, install a
separate EMERGENCY STOP push button that can be operated at
the equipment.
If a fault reset is made with the reference signal still present, then a
restart will occur. Verify that it is permissible for this to happen,
otherwise an accident may occur.
Do not modify or alter anything within the drive.
Before programming or operating the SD500 Series, initialise all
parameters back to factory default values.
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. INTRODUCTION
1.1. Ethernet Networks
1.1.1. Introduction
Ethernet is used to designate a family of frame-based computer
networking technologies for local area networks (LANs). It was
mainly developed by Xerox Corporation, Intel Corporation and
Digital Equipment Corporation (DEC) companies in 1980, and has
continued evolving since then.
Ethernet defines a number of wiring and signalling standards for the
physical layer and the frame formats of the data link layer of the OSI
model.
Ethernet is the most commonly used LAN technology because it
achieves a good balance between speed, cost and installation
easiness. Additionally, it is very accepted in the market and supports
all popular virtual network protocols.
Some of the advantages of Ethernet that makes it the ideal network
technology for most current computer users are:
Easy installation and maintenance, together with their low cost.
Flexibility for interconnecting different topologies.
Stable standard that allows interconnecting devices from
different manufacturers.

1.1.2. Types of Ethernet Networks
There are different implementations for Ethernet network, according
to the physical environment referred. The existing Ethernet
technologies differ in the following characteristics:
Transmission speed: Transmission capacity of the
environment in Mbps.
Cable type: Used technology of the physical layer.
Maximum length: Maximum allowed distance between two
adjacent nodes (without repeaters).
Typology: Defines the performance of the central linking
points.

1.2. Description of the Ethernet Board
The Ethernet board for SD500 drives allows integrating the drive in a
LAN (Local Area Network). It supports the TCP/IP standard
communication protocol and the industrial application layer protocol
Ethernet/IP for industrial automation applications.
Thanks to this board, the drive can be controlled and monitored by the
user or through a PLC sequence program or any master device (client).
