Gem6K Hardware Installation Guide
Installation Guidelines
Gem6K drives are made available under “Restricted Distribution” for use in the
“Second Environment” as described in BS EN 61800-3: 1996, page 9.
Cabinet Mounting
For Electromagnetic Compatibility, cabinet mounting is not required. However,
Gem6K drives have high voltage terminals—for safety purposes, the drive must
not be user accessible during normal operation.
Drive Mounting
The Gem6K drive is designed to be mounted to an earthed metal panel. For EMC
performance, mount the mains filter to the same panel, as close to the drive as
possible. See the
EMC Installation
drawing at the end of this appendix.
Cable Routing
Route high power cables (motor and mains) at right angles to low power cables
(communications and inputs/outputs). Never route high and low power cables
parallel to each other.
Cable Shielding
All cables must maintain high integrity 360 degree shielding. Compumotor CE
cables are fully shielded and provide the required screening. When you install
limit switches and other inputs/outputs, you must observe proper noise immunity
standards. See the
EMC Installation
drawing at the end of this appendix.
Ethernet Cables
Install a ferrite ring core (toroid) on your Ethernet cable. Wrap the cable through
the ferrite eight times, as shown in the installation drawings. Make the cable length
between the ferrite and drive as short as possible.
A recommended toroid is listed below, along with its specifications.
Manufacturer:
Phillips; part number TL42/26/13-3C90 4330 030 35522 MU

The ferrite you choose must meet or exceed the specifications above.
Ferrite Absorbers
To further increase product immunity and reduce product emissions, you must add
clip-on or other ferrite absorbers to certain cables. (See the installation drawings at
the end of this appendix for specific locations.) Compumotor recommends a ferrite
with at least 200 ohm impedance at 100 MHz, such as:
Steward Ferrite
part number 28A2024
Fair-Rite
part number 0443164151
(These ferrites are available from Compumotor, part number 47-015956-01)
Expansion I/O
For EMC-sensitive applications requiring expansion I/O, or CE compliant installa-
tions, use Parker Compumotor’s EVM32-II.
