** See section 4.5
on page 71 for more information.
4.1.2 Ground connections
Size 1
On a size 1, the supply and motor ground connections are made using
the studs located either side of the drive near the plug-in power
connector. Refer to Figure 4-1 on page 66.
Size 2
On a size 2, the supply and motor ground connections are made using
the grounding bridge that locates at the bottom of the drive. See Figure
4-5 for details.
Size 3
On a size 3, the supply and motor ground connections are made using
an M6 nut and bolt that locates in the fork protruding from the heatsink
between the AC supply and motor output terminals. See Figure 4-6 for
details.
Size 4, 5 and 6
On a size 4, 5 and 6, the supply and motor ground connections are
made using an M10 bolt at the top (supply) and bottom (motor) of the
drive. See Figure 4-7 on page 69.
The supply ground and motor ground connections to the drive are
connected internally by a copper conductor with a cross-sectional area
given below:
Size 4: 19.2mm
2
(0.03in
2
, or slightly bigger than 6 AWG)
Size 5: 60mm
2
(0.09in
2
, or slightly bigger than 1 AWG)
Size 6: 75mm
2
(0.12in
2
, or slightly bigger than 2/0 AWG)
This connection is sufficient to provide the ground (equipotential
bonding) connection for the motor circuit under the following conditions:
If the necessary conditions are not met, an additional ground connection
must be provided to link the motor circuit ground and the supply ground.
