POWER ELECTRONICS
SDRIVE 700
INSTALLATION AND CONNECTION
15
We recommend installing the drive according to the following connection:
Figure 1.2 Power wiring connection
Note:
It is recommended to use an earth cross section equal or higher than active wires cross section.
CAUTION
Line voltage must never be connected to U, V and W terminals. Otherwise the drive will be
damaged.
2.4.2.
Control Wiring
Control wiring should be installed as far as possible from the power wiring. If you have to pass the
control wiring next to the power wiring it should do perpendicularly. The cable should be screened
and the shield should be connected to ground.
Do not use voltages of 24Vdc and 220Vac into the same cable.
2.4.3.
Observations before Trial Run
Before applying voltage, we recommended to check that the power wiring is connected correctly
and to verify that the connections are correctly fastened.
It is recommended to close the doors of SD700 before applying voltage the first time.
Before applying voltage to the drive and configuring it, make sure the line voltage is compatible
with drive power supply. On the contrary, the drive will be damaged.
After applying voltage to the drive, verify the display is turned on and the status led of the DC bus
is also illuminated.
Check line voltages when the display is lit. If the drive does not read one of the 3 phases then
check input power wiring.
Before starting the SD700, the parameters should be programmed correctly for proper operation
of the motor. Ensure the correct motor parameters are entered before giving the first “start”
command to the drive.
WARNING
It is absolutely necessary that the installer guaranties the correct observance of the law and the
regulations that are in force in those countries or areas where this device is going to be installed.
