Installation put in service
This chapter includes a checklist with steps that should be taken before the PCD 8 s-series is switched on and
put into operation.
3.1.
Safety instructions for installation and initial installation
National regulations in installation and operation of electrical equipment must be respected.
WARNING The PCD 8 s-series test system is not suitable for use in an explosive atmosphere.
WARNING Connect the EUT only after the initial system setup has finished.
3.1.1.
Qualifications of the staff
Basic knowledge of electrical engineering and electromagnetic compatibility is required to service the unit. The
national regulations for installation of electrical equipment as well as the safety at work of electrical equipment
must be known to the user.
3.1.2.
Installation
The PCD 8 s-series system conforms to protection class 1. Local installation regulations must be respected to
ensure the safe flow of leakage currents.
WARNING Operation without a ground connection is forbidden!
Two independent ground connections are necessary - one for the test system and one for the EUT. These must
be connected back to the local permanent installation or to a fixed, permanent ground conductor.
Operate the equipment only in dry surroundings. Any condensation that occurs must be allowed to evaporate
before putting the equipment into operation. Do not exceed the permissible ambient temperature or humidity
levels. Use only officially approved connectors and accessory items.
Ensure that a reliable return path for the interference current is provided between the EUT and the generator.
The ground reference plane and the ground connections to the instruments, as described in the relevant test
standards, serve this purpose well.
The test system may only be opened by a qualified specialist upon specific instruction given by the manufacturer.
The equipment works, on principle, with two independent power supplies, one for the generator and one for the
EUT. The PCD 8 s-series must be disconnected from both sources before any modifications to the test setup are
undertaken. Besides the mains connections themselves, certain components also operate at high voltages, and
are not provided with any form of extra protection against accidental contact.
The system complies with the safety requirements of IEC/EN 61010-1 (Safety requirements for electrical
equipment for measurement, control, and laboratory use).
It is the user’s responsibility to ensure that the test rig does not emit excessive electromagnetic interference (EMI)
that might affect other equipment. The test system itself does not produce any excessive radiation; however, the
injection of interference pulses into the EUT can result in the device and/or its associated cables radiating EMI.
To avoid radiating unwanted interference the standards organizations recommend that the test setup be in a
Faraday cage.
Since the purpose of the test system is to produce interference signals for interference immunity testing, the
requirements in the IEC/EN 61000 series concerning limiting the radiated EMI can only be complied with by
operating the test system inside a Faraday cage.

Operating Manual V 2.02 12 / 53
Mounting positioning plates
Screw the base plates (positioning plates) of the sync unit and of the coupling unit, with the knurled screws to the
foreseen holes on the outside of the decoupling networks. If PCD 8 s decoupling networks are not placed
correctly, the positioning plates cannot be screwed on.
Mounting the Sync unit
Add the Sync unit in the middle of the positioning plate and press it slightly down into the positioning holes. Fix
the Sync unit by pushing the black quick snap-on knobs (A) down. Connect the synch lines (safety banana
connector) to the decoupling units (B). Connect the ground terminal of the sync unit to the decoupling network
(C).

AMETEK CTS PCD 8 s-series
Operating Manual V 2.02 13 / 53
Assembly for IEC coupling
For IEC coupling, add the coupling module SCB in the middle of the big positioning plate and press it slightly
down into the positioning holes. Fix the SCB by pushing the 4 black quick snap-on knobs down (A). Connect the
ground terminal of the SCB to the decoupling network (B). The PCD 8 s-3-690-1000-100 is now ready to use.
NOTE For the PCD 8 s-3-690-1000-200, the 4 fan motors must also be connected to the power
supply units and put into operation. Only use the two power supply units included in the
scope of delivery; 2 fan motors can be connected to each power supply unit.
NOTE Because of the coupling capacitors, the mains voltage can be present at the HV connectors
when the EUT power supply is switched on. The HV connectors must therefore always be
hooked up to the generator before the mains and the EUT power supply are switched on.
NOTE Never run the CDN with a loose end of the coupling unit. All connectors need to be plugged.
NOTE The whole test assembly should be supplied from the same mains connection in order to
prevent uncontrolled flow of pulse current in other parts of the system. Installation in a
Faraday cage ensures that non-associated items and equipment are not disrupted by pulses
radiated from the cabling or the device under test. Connections to the EUT must be of low
impedance and be made with high contact pressure. Otherwise welding or arcing might occur
at the contact points.

AMETEK CTS PCD 8 s-series
Operating Manual V 2.02 14 / 53
Assembly for ANSI coupling or additional IEC lines coupling mode
For ANSI coupling or additional IEC lines coupling add 2 coupling modules SCB on the big positioning plate and
press them slightly down into the positioning holes. Fix the SCB’s by pushing the black quick snap-on knobs
down (A). Connect the ground terminals of both SCB’s to the decoupling networks (B).
NOTE Because of the coupling capacitors, the mains voltage can be present at the HV connectors
when the EUT power supply is switched on. The HV connectors must therefore always be
hooked up to the generator before the mains and the EUT power supply are switched on.
NOTE The whole test assembly should be supplied from the same mains connection in order to
prevent uncontrolled flow of pulse current in other parts of the system. Installation in a
Faraday cage ensures that non-associated items and equipment are not disrupted by pulses
radiated from the cabling or the device under test. Connections to the EUT must be of low
impedance and be made with high contact pressure. Otherwise welding or arcing might occur
at the contact points.
3.2.4.
Grounding
The instruments conform to the safety requirements, but with an increased leakage current given by the
decoupling filter. Operate the equipment only in dry and clean surroundings. Any condensation that occurs must
be allowed to evaporate before putting the equipment into operation. Do not exceed the permissible ambient
temperature or humidity given in the IEC specification.
NOTE Operation without a protective earth connection is forbidden!
NOTE Only handle the test rig or the device being tested when the EUT power supply is switched off and the
generators test sequence has been halted or aborted.

AMETEK CTS PCD 8 s-series
Operating Manual V 2.02 15 / 53
It is recommended to connect the PCD 8 s through a properly rated power switch device, which should be
located close to the test setup. To ensure an easy and quick access to the EUT power, the switch should be
clearly and visibly labelled as a device for «EUT power on/off» switching. The inhouse power distribution needs
to be equipped with a proper circuit breaker and an emergency off button as per IEC 61010-1.
Leakage current
Local installation regulations must be respected to ensure the safe flow of leakage currents. Use only nationally
approved connectors and accessory items.
Ensure that a reliable return path for the interference current is provided between the EUT and the coupling
network. The reference ground plane and the earth connections to the instruments as described in the relevant
test standards serve this purpose well.
Earth connection
The earth connection terminal ensures a positive link to the copper earth rail connected on the CDN housing.
On the CDN unit «EUT power out» side it is electrically connected to the middle connection, identified by «earth
connection» symbol. In case of a test installation with a solid earth (e.g. a Faraday cage), this earth terminal can
be used to form a star-connection point for the earth wires of the test setup.
EUT Supply protection
Dimensioning of EUT supply and rating of fuse protection (AC or DC), must conform with National prescriptions
and EUT requirements. An inappropriate arrangement, mounting, cabling and/or handling of the device under test
or the protective elements can make the protective features that are incorporated in the concept of the device
worthless.
NOTE The in-house power distribution needs to be equipped with a proper circuit breaker and an emergency
off button as per IEC/EN 61010-1.
NOTE Do not mismatch the EUT power input of the CDN and the EUT power output. Use only the delivered
isolated allen key to screw the cables to the terminals. Never touch the terminals during the EUT power
is on.

through unused channels (screwed connectors). It is recommended to screw the safety
banana plug adapters (PCA BPSET) on the unused connectors.
The earth connection lug on the power supply input serves to ensure a good connection to the protective earth on the
coupling network. Every test rig must be planned carefully. All the instrumentation should be readily accessible and
rigidly positioned.
NOTE The whole test setup should be supplied from the same mains connection to prevent an
uncontrolled flow of pulse current in other parts of the system. Installation in a Faraday cage
ensures that non-associated items and equipment are not disrupted by pulses radiated from
the cabling or the device under test. Connections to the EUT must be of low impedance and
be made with high contact pressure otherwise welding or arcing might occur at the contact
points.
NOTE Only handle the test rig or the device being tested when the EUT power supply is switched
off and the generators test sequence has been halted or aborted.

Selecting the PCD 8 s in test-mode (compact NX)
To be able to select the PCD 8 s for coupling, it must first be activated as an external coupler as shown in
chapter 3.3.1. The PCD 8 s can then be selected as a coupling network in the various test menus.
Example Quickstart: In the lower left corner of the test window
you can see which coupling network is currently selected (1).
Open the coupling setting menu (2).
Change the coupling mode from Internal to the PCD 8 s(3) to be
used and press OK (4).
In the lower left corner of the test window you can see now the
selected PCD 8 s.
