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 / +34 96 136 65 57) 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).
