Electrical
Connecting & Disconnecting Power Mains
The earth connection for the Auxiliary Box of the AT6n00
is provided through its make-first/break-last earth terminal
on the power mains connector. You must reliably earth
the Auxiliary Box’ protective earth connection.
Using an Isolation Transformer
The mains voltage for the Auxiliary Box is limited to 120
VAC nominal for the AT6400-120, and 240 VAC for the
AT6400-240 and AT6200. If your mains voltage is
higher, use an isolation transformer located between the
power mains and the Auxiliary Box. Your isolation
transformer should be insulated to ~2300V rms.
Do not interrupt the protective earth conductor between the
source mains and the isolation transformer’s secondary.
The core of the isolation transformer and the drive’s
protective conductor terminal must both be connected to
the mains protective earth conductor.
CAUTION — For safety reasons, do not use an
autotransformer.
Adding Line Fuses
Line fuses need to be added to protect the transformer and
associated wiring. If the live wire cannot be readily
identified, fuse both phase conductors. The value of fuse
required is given by: (1.5 x VA)/(supply volts) [amps]
Fuse types should be anti-surge HBC.
WARNING —
Safety Ground (Earth Ground)
should never be fused.
Installation
Installing the AT6n00 Card
Install the AT6n00 card itself into your computer per the
instructions on page 5 of this Installation Guide. In order
for the AT6n00 card to be CE compliant, it must be
mounted in a CE-compliant computer. The AT6n00 will
not compromise the EMC integrity of the host computer
or its peripherals.
Installing the Auxiliary Box in an External
Enclosure
I n t r o d u c t i o n
The measures described in this section are primarily for the
purpose of controlling conducted emissions. To control
radiated emissions, all peripheral equipment for the
AT6n00 control system must be installed in a steel
equipment cabinet which will give adequate screening
against radiated emissions. This external enclosure is also
required for safety reasons. There must be no user access
while the equipment is operating. This is usually achieved
by fitting an isolator switch to the door assembly.
To achieve adequate screening of radiated emissions, all
panels of the enclosure must be bonded to a central earth
point. The enclosure may also contain other equipment and
the EMC requirements of these must be considered during
installation. Always ensure that components are mounted
in such a way that there is adequate ventilation.
Preparing the Auxiliary Box: The Auxiliary Box for the
AT6n00 must be mounted to a conductive panel of the
enclosure. The Auxiliary Box is shipped with no paint
affixed to its mounting surfaces. Before mounting the
Auxiliary Box, remove the paint from the mounting
surface of the enclosure. This is to guarantee a good high-
frequency connection between the Auxiliary Box case and
the enclosure.
