Note: For SED2 IP20 frame sizes A…C, we recommend to use gland plates (available as optional accessory,
mentioned below). Gland plates simplify and improve the connection of shielded cables. They allows for
better contact of the shields and thus optimize the EMC behavior of the VSD.

Warning and safety instructions
Caution
♦ Check to ensure that the VSD and motor are correctly sized for the supply
voltage. Check that the VSD corresponds to at least the motor output
♦ Check to ensure that the mains cables are correctly sized for the anticipated
use
♦ Check to ensure that appropriate circuit breakers or fuses exist between the
mains and the VSD
Warning
Never use high-voltage insulation test on any cables connected to the VSD.
Danger
♦ Always isolate the power cables before connecting them to the VSD
♦ Check to ensure that the terminal cover was replaced properly after connecting
the power and motor cables
♦ Never switch on the VSD with the cover open
♦ Always use insulated tools when working on the incoming power supply and the
motor terminals
