Installation
Connect the drive according to the following diagram. Ensure that the motor terminal box
connections are correct. There are two standards in general: Star and Delta. It is essen-
tial to ensure that the motor is connected in accordance with the voltage at which it will
be operated. For more information, refer to the diagram below.
Please refer to chapter 10 for the recommended cabling and wiring sizing.
It is recommended that the power cabling should be 4-core PVC-insulated screened
cable, laid in accordance with local industrial regulations and codes of practice.
The ground terminal of each MOVITRAC
®
LTP should be individually connected
directly
to the site earth (ground) busbar (through the filter if installed) as shown.
MOVITRAC
®
LTP ground connections should not loop from one drive to another. They
should also not loop to or from any other equipment. Ground loop impedance must
conform to local industrial safety regulations. To meet UL regulations, UL approved ring
crimp terminals should be used for all earth wiring connections.
