REGULATORY COMPLIANCE UL AND CE
96 IPA Hardware Installation Guide
Use shielded cabling with braided and bonded headshells. Parker EMC cabling requires no additional cable
preparation. All motor connections must be made using a high quality braided-screen cable. Cables using a
metalized plastic bandage for an earth screen are unsuitable and in fact provide very little screening. Care must be
taken when terminating the cable screen, the screen itself is comparatively fragile; bending it round a tight radius
can seriously affect the screening performance. The selected cable must have a temperature rating which is
adequate for the expected operating temperature of the motor case.
All cables must maintain high integrity 360 degree shielding. Parker CE cables are fully shielded and provide the
required screening. When you install limit switches and other inputs/outputs, you must observe these noise
immunity procedures and practices.
Route cables as shown in Typical LVD/EMC Installation. 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.
Mount filters close to the drive and keep the supply wiring as short as practical. Attempt to lay out the wiring in a
way that minimizes cross coupling between filtered and non-filtered conductors. This means avoiding running wires
from the output of a filter (clean signals) close to those connected to its input (noisy signals). Where you wish to
minimize the cross coupling between wires avoid running them side-by-side one another, if they must cross, cross
them at 90° to each other. Keep wiring affixed and supported and close to cabinet metalwork.
Cables may require the use of ferrite core suppressors. Some installations may require that you take
additional EMC measures. To further increase product immunity and reduce product emissions, you may add clip-
on ferrite absorbers to all cables. Parker recommends ferrites with at least 200 ohm impedance at 100 MHz, such
as the following:
Note: These ferrites are available from Parker Hannifin, part number 47-015956-01. For larger
diameter cables (up to 0.722 in O.D.), we recommend Fair-Rite part number 0444176451.
Your Installation may require additional EMC installation hardware (as shown in illustrations). The
following clamp kits are available from Parker:
Enclosure Mounting Clamps
R-Clamp Kit (10 per) for models IPA04-HC
to IPA15-HC
R-Clamp Kit (10 per) for models AR-20xE
and AR-30xE
Clamshell Clamp Kit (2 per) for all models
Note: The Control power input also requires a mains power line filter, varistors, and fuses in
order to comply with the relevant CE directives.
