CAUTION
Read carefully the following instructions to ensure correct electrical installation.
Otherwise, it could cause damage to the equipment and lead to personal injuries.
Basic Configuration
Appropriate safety equipment must be used and the unit properly connected in order to guarantee correct
operation. A drive which is incorrectly installed or set up can result in system malfunction, component
damage or a reduced lifespan. You must read this manual thoroughly before proceeding.
AC Power
Supply
Use a power supply with a voltage range compatible with the
selected drive.
SD300 drives are available for TN and TT grids, or IT grids
(floating earth). Check the serial number to ensure the correct
drive selection.
Circuit Breaker
Select circuit breakers or fuses in accordance with applicable
national and local codes. We recommend using specified circuit
breakers or fuses to operate with the drive.
Magnetic
contactor
(optional)
Install if necessary. When installed, do not use it for the purpose
of starting or stopping the drive.
AC reactor
(optional)
Use an AC reactor if you wish to improve the input power factor
of the power supply, reduce harmonics or supress external
surges.
SD300
Installation
Install the drive following the recommendation within this
manual in relation with the cooling requirements, position,
clearances, wiring access and ground connection.
DC reactor
(optional)
DC reactors also contribute to improving the power factor and
harmonics reduction, but DC reactors are usually used in
facilities with higher power supply capacity.
Motor cables
Select and install the motor cables according to the
recommendation within this manual and the applicable national
and local codes, otherwise you could cause EMC filtering
malfunction and motor damage.
Motor
Do not connect power factor capacitors, surge arrestors or RFI
filters to the output side of the drive.
