3.1.3 - Power terminal block location
Details of the position of various terminal blocks in the cabinet are to be found in the layout sheet of the electrical plan THxxxxx
supplied with the cabinet.
For wiring details of the Power and control terminal blocks, refer to the "Terminal block" folio.
3.1.4 - Cables and fuses
The following characteristics only describe equipment containing one drive. For other equipment (high power > 940T and 680TH,
DC BUS, equipment with several drives), the cross-sections are specific and must be re-calculated. If necessary contact Leroy-
Somer. For this equipment, it should be noted that the I
L
is equal to sum of I
L
for each drive present in the cabinet. The line
protection will therefore need to be re-calculated.
• It is the responsibility of the user to connect and fit protective devices for the Powerdrive MD Smart in accordance
with the legislation and regulations in force in the country of use. This is particularly important as regards the size
of the cables, the type and rating of fuses, the earth or ground connection, powering down, acknowledging trips, isolation
and protection against overcurrents.
• The installation must have a short-circuit current (Isc) > 20 I
L
at the point of drive connection.
• This table is given for information only, and must under no circumstances be used in place of the current standards.
