EMC Plate and cable arrangement on ATV212H drives
ATV212W connection plates
There are connection plates on the lower sections of the variable speed drives. These plates are drilled in order
to allow cables to be routed through them via cable glands. Cable glands must be ordered separately; they are
not supplied with the drive.

ATV212H 075N4 to D22N4S
1 EMC plate supplied with the ATV212 drive.
2 ATV212 drive.
3 Non-shielded power supply wires or cables.
4 Non-shielded wires for the output of the relay contacts.
5 The shields for cables 6 and 7 must be securely attached to the EMC
plate with stainless steel clamps not supplied with the product. See
catalog to order the clamps (ref. TM200RSRCEMC). Strip cables 6
and 7 to expose the shields. Apply appropriately-sized clamps
around the stripped portion of the cables and fasten them to the EMC
plate.
6 Shielded cable for connection to the motor, with shield connected to
ground at both ends. This shield must not be interrupted. If
intermediate terminal blocks are used, they must be in EMC-shielded
metal boxes.
7 Shielded cable for connection to control/command devices. For
applications which require a large number of conductors, small
cross-sections must be used (0.5 mm
2
, 20 AWG). This shield must
not be interrupted. If intermediate terminal blocks are used, they
must be in EMC-shielded metal boxes.
8 Ground screw. Use this screw for the motor cables on the low power
rated drives, as the ground screw on the heatsink is inaccessible.
If using an additional input filter, connect it directly to the line supply
with an unshielded cable. Then make connection 3 on the drive using
the filter output cable.
Although there is a high frequency equipotential ground connection
between the drive, motor, and cable shielding, you must still connect
the PE protective conductors (green-yellow) to the appropriate
terminals on each of the devices. You may also need to disconnect the
shield at the motor end for very long cable runs to alleviate noise
generation.
