SAFETY INSTRUCTIONS
SAFETY INSTRUCTIONS
IMPORTANT!
Read carefully this manual to maximize the performance of the product and to ensure its safe use.
In order to appropriately use the drive, please, follow all instructions described in the installation manual
which refer to transportation, installation, electrical connection and commissioning of the equipment.
Power Electronics accepts no responsibility or liability for partial or total damages resulting from
incorrect use of equipment.
Please, pay careful attention to the following recommendations:
WARNING
Do not run the drive with the front cover removed.
Otherwise, you may get an electric shock.
The drive does not remove the voltage from the input terminals of the drive. Before working on
the drive, isolate the whole drive from the supply.
If you do not remove the power supply, you may get an electric shock.
Do not remove the cover except for periodic inspections or wiring, even if the input power is not
applied.
Otherwise, you get an electric shock.
Before opening the covers for wiring or periodic inspections, ensure DC voltage has been fully
discharged. Check with a multimeter the following measures:
Measure between the output power busbars U, V, W and the cabinet and check that the
voltage is around 0V.
Measure that the DC link terminals +, - and chassis voltage are below 30VDC.
Otherwise, you may get an electric shock.
Operate the drive 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 abrasions, excessive stress, heavy loads or pinching.
Otherwise, you may get an electric shock.
Do not make any insulation or voltage withstand tests on the motor while the drive is connected.

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 is 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
The SD300 are carefully tested and perfectly packed before delivering.
In the event of transport damage, please ensure to notify the transport agency and POWER
ELECTRONICS: 902 40 20 70 (International [phone]), or your nearest agent, within 24hrs
from receiving the goods.
UNPACKING
Make sure model and serial number of the variable speed drive are the same on the box, delivery
note and unit.
Each variable speed drive is delivered with Hardware and Software technical manuals.
RECYCLING
Packing of the equipment should be recycled. For this, it is necessary to separate the different
included materials (plastic, paper, cardboard...) and deposit them in their relevant recycling areas.
Waste products of electric and electronic devices should be selectively collected for their correct
environmental management.
ELECTROMAGNETIC COMPATIBILITY (EMC)
The drive is intended to be used in industrial environments (Second Environment). It achieves
compliance with C3 category defined in IEC/EN 61800-3 standard when the installation
recommendation within this manual are followed.
Select communication and control system according to the drive EMC environment. Otherwise,
systems could suffer from interferences due to a low EMS level.

SAFETY INSTRUCTIONS
SAFETY
Before operating the drive, read this manual thoroughly to gain an understanding of the unit. If any doubt
exists, please contact POWER ELECTRONICS, (902 40 20 70 / [phone]) or your nearest
agent.
Wear safety glasses when operating the drive with power applied or for when the front cover is
removed.
Handle and transport the drive following the recommendations within this manual.
Install the drive according to the instructions within this manual and local regulations.
Do not place heavy objects on the drive.
Ensure that the drive is mounted vertically and keeping the minimum clearance distances.
Do not drop the drive or subject it to impact.
The SD300 drives contain static sensitive printed circuits boards. Use static safety procedures when
handling these boards.
Avoid installing the drive in conditions that differ from those described in the Environmental Ratings
section.
CONNECTION PRECAUTIONS
To ensure a correct operation of the drive, it is recommended to use a SCREENED CABLE for the
control wiring.
The motor cable should comply with the requirements within this manual. Due to increased leakage
capacitance between conductors, the external ground fault protection threshold value should be
adjusted ad hoc.
Do not disconnect motor cables if the input power supply remains connected.
The internal circuits of the SD300 Series will be damaged if the incoming power is connected and
applied to the output terminals (U, V, W).
Do not use power factor correction capacitor banks, surge suppressors, or RFI filters on the output
side of the drive. Doing so may damage these components.
Before wiring the terminals, make sure that the inverter keypad display is turned off and the front
cover is off as well. The inverter may hold a high voltage electric charge long after the power supply
has been turned off.
TRIAL RUN
Verify all parameters before operating the drive. Alteration of parameters may be required depending
on application and load.
Always apply voltage and current signals to each terminal that are within the levels indicated in this
manual. Otherwise, damage to the drive may occur.
EARTH CONNECTION
Ground the drive and adjoining cabinets to ensure a safe operation and to reduce electromagnetic
emission.
Connect the input PE terminal only to the dedicated PE terminal of the drive. Do not use the case,
nor chassis screws for grounding.
Ground the drive chassis through the labelled terminals. Use appropriate conductors to comply with
local regulations. The ground conductor should be connected first and removed last.
Motor ground cable must be connected to the PE output terminal of the drive and not to the
installation’s ground. We recommend that the section of the ground conductor (PE) is equal or
greater than the active conductor (U, V, W).

INTRODUCTION
1. INTRODUCTION
The SD300 is a high performance general purpose AC drive suitable for demanding heavy duty applications
that require high starting torque and precise control. The dual duty rating of the SD300 (IP20) also ensures
compatibility with less demanding normal duty loads. The IP66/NEMA4X option further enhances the
flexibility of the product to meet the most severe environments.
The SD300 is entirely suitable for applications such as water treatment and irrigation, food and beverage,
ventilation systems, material handling, lifting systems, textiles, plastic, wood processing...in fact, any
application where OEMs need to control and automate apparatus and machinery.
Some of its outstanding features are:
Easy-to-use, compact and robust product, offering users savings in time and space.
Space saving design with side by side mounting.
The overall motor control features and the motor/drive protection functions limit unexpected machine
downtime.
A built-in display with keypad offers programming and operation capabilities. Remote LCD display
option.
Integrated communication port and Modbus protocol allows the SD300 to exchange data for
machine/process monitoring, control and preventive maintenance.
Safe Torque Off (STO) as standard.

Maximum applicable capacity is indicated in the case of using a 4-pole standard motor (200 and 400V
classes are based on 220 and 440V, respectively).
For the rated capacity, 200 and 400V class input capacities are based on 220 and 440V, respectively.
The rated output current is limited depending on the setup of carrier frequency [G4.4].
The output voltage becomes 20~40% lower during no-load operations to protect the drive from the
impact of the motor closing and opening (0.4~4.0kW models only).
Dual rating is supported except IP66/NEMA 4X.
