Appendix – EMC Compliance
Appendix
EMC Compliance
The Quattro DC drive requires EMC
Compliance (EN12015 and EN12016) to
function at the highest performance level
possible. The following pages will provide the
user with an installation guideline for field
personnel regarding proper metallic bonding
for EMC compliance. All necessary metallic
bonding within the Quattro cabinet will be
performed at the factory.
In order to be compliant with conducted and
radiated emissions standards, it is critical that
the motor leads are coupled correctly to the
chassis of the Quattro product. Ensuring
proper connections through the conduit plate
does this. The conduit plate is located on the
upper right hand corner of the cabinet.

Method 1:
1. Use rigid conduit combined with
appropriate conduit couplings for an
acceptable metallic bond to the conduit
plate. Note: The conduit can only contain
the armature and field lines. No
communication or encoder feedback wires
can be run through this conduit.

Proper bonding on motor wiring can be
achieved by using one of the following two
methods:

2. Verify the M5 screws, as seen in Figure
, are tight and securing the conduit plate
to the top-hat
3. Verify the M8 screws, as seen in Figure 1
are properly connected and secure.
Method 2:
1. Use braided, shielded leads for the DC
armature and for the motor field
connections. Note: When shielded multi-
conductor wire is used, it is very important
to use termination couplings that are
designed for this type of installation.
These couplings are designed to make a
bond to the braid, which will complete the
metallic connection to the chassis.

3. Verify the M8 screws, as seen in Figure 1
are properly connected and secure.
Proper bonding on encoder cables and
communication wiring may be seen in Figure
. All shielded multi-conductor cables used
for communications or for the encoder
feedback must be the braided type.

lower part on the card cage near the customer
I/O board to mount a braided clamp.
