Installation
This however does not apply to IP54/NEMA 12 units
as they are designed for wall mounting and VLT
8152-8600, 380-480 VAC and VLT 8042-8062,
200-240 VAC in IP20/NEMA 1 enclosure.
•
Use starwashers and galvanically conductive
installation plates to secure good electrical
connections for IP00/Chassis and IP20/NEMA
1 installations.
•
Avoid using unshielded/unarmored motor or
control cables inside cabinets housing the drive(s),
whenever this can be avoided.
•
An uninterrupted high frequency connection
between the AFD and the motor is required
for IP54/NEMA 12 units.
The next illustration shows an example of an
EMC-correct electrical installation of an IP 20/NEMA
1 AFD; the AFD has been installed in a cabinet
(enclosure) together with an output contactor and is
connected to a PLC which, in this example, is installed
in a separate cabinet. For IP 54/NEMA 12 units, VLT
8152-8600 (380-480 V) and VLT 8042-8062 (200-240
V) units in IP20/NEMA 1 enclosures; shielded cables
are connected by using EMC conduits to assure
proper EMC performance. (See next illustration.)
Other ways of making the installation may give as
good an EMC performance, provided the above
engineering practice guidelines are followed.
Please note, that when the installation is not made
according to these guidelines as well as when
unshielded cables and control wires are used, some
emission requirements are not complied with, although
the immunity requirements are fulfilled.
