CAUTION
Please read the following instructions for proper electrical installation .
Otherwise, it could result in damage to equipment and personnel.
The access to the SD750 Kompakt power terminals can be only done removing the front cover.
The front cover can be removed unscrewing the 4 screws located in the four cover corners. The
SD700 KOMPAKT cover integrates cooling fans and a display. Ensure disconnect these fans and

NOTICE
Consult the recommended tightening torque for both mechanical and electrical connections in section
“
TORQUE AND SCREW SIZING
”.
Basic configuration
Select the appropriate safety equipment and perform the wiring properly to ensure proper operation of
the equipment. Incorrect application or installation can lead to malfunction of the drive and consequently
reduce its life or damage its components. Read and understand this manual thoroughly before performing
any operations.
AC Power
Supply
Use a power supply according to the selected drive.
The SD750 Kompakt drives are provided to operate with the
neutral connected to the ground.
Earth leakage
circuit breaker
(ELB)
Select circuit breakers or fuses in accordance with applicable
national and local codes. We recommend using specified
circuit breakers or fuses to operate with drive.
Inline Magnetic
Contactor
Install if necessary. When installed, do not use it for the
purpose of starting or stopping the drive.
Input inductance
The input inductance (CHOKE) reduces the current and
voltage harmonic distortion, protects the drive from main
disturbances decreasing the risk of damage due to over-
voltages.
Installation and
wiring
To operate the drive reliably, install the drive in the proper
orientation and with proper clearances. Incorrect terminal
wiring could result in the equipment damage.
Motor
Do not connect power factor capacitors, surge arrestors or
radio noise filters to the output side of the drive.
