About this Reference Manual
The purpose of this Reference Manual is to familiarize users with CPC 100 and
its various application fields. It contains helpful instructions on how to use
CPC 100 safely, properly, and efficiently.
Following these instructions will help you to prevent danger, repair costs and
possible down time due to incorrect operation. Furthermore it ensures the
reliability and life-cycle of CPC 100.
CPC 100 must be used in observance of all existing safety requirements from
national standards for accident prevention and environmental protection.
Reading the CPC 100 manual alone does not release the user from the duty of
complying with all national and international safety regulations relevant for
working with CPC 100, for example, the regulation EN50191 "Erection and
Operation of Electrical Test Equipment”.

Safety Instructions for CPC 100 and its
Accessories
Before operating CPC 100, read the following safety instructions carefully. Do
not turn on and do not use CPC 100 without understanding the information in
this manual. If some points of the safety instructions are unclear, please contact
OMICRON electronics.
Principle Use According to Regulations
•CPC 100 should only be used in a safe manner, mindful of the dangers while
paying attention to the Reference Manual, and when it is in a technically
sound condition and when its use is in accordance with the regulations. In
particular, avoid disruptions that could in turn affect safety.
• If you have a cardiac pacemaker, do not use CPC 100! Before operating
CPC 100, make sure there is no person with a cardiac pacemaker in the
immediate vicinity.
•CPC 100 is exclusively intended for the application fields specified in detail
in ”Designated Use” on page 1-13.
Any other use is deemed not to be according to the regulations. The
manufacturer/distributor is not liable for damage resulting from improper
usage. The user alone assumes all responsibility and risk.
• Following the instructions provided in this Reference Manual is also
considered part of being in accordance with the regulations.
• Do not open the CPC 100 housing.
Orderly Measures
• The Reference Manual, or alternatively the e-book in PDF format, should
always be available on the site where CPC 100 is being used.
• Personnel assigned to use CPC 100 should carefully read the Reference
Manual - in particular this section on safety instructions - before beginning to
work with it. On principle this also applies to personnel who only occasionally
work with CPC 100.
• Do not undertake any modifications, extensions, or adaptations to CPC 100.
• Use CPC 100 in conjunction with original accessories only.
DANGER!

Operator Qualifications and Primary Responsibilities
• Testing with CPC 100 should only be carried out by authorized and qualified
personnel. Clearly establish the responsibilities!
• Personnel receiving training, instruction, direction, or education on CPC 100
should remain under the constant supervision of an experienced operator
while working with the equipment.
Safe Operation
When setting CPC 100 into operation, follow the instructions in ”Putting
CPC 100 into Operation” on page 2-46.
If you have a cardiac pacemaker, do not use CPC 100! Before operating
CPC 100, make sure there is no person with a cardiac pacemaker in the
immediate vicinity.
Never use CPC 100 without a solid connection to ground with at least 6mm².
Use a ground point as close as possible to the test object.
Power Supply
• Supply CPC 100 only from a power outlet that has protective earth (PE).
• An error message (313) appears if either the PE connection is defective or
the power supply has no galvanic connection to ground. In this case, make
sure that the PE connection is intact. If the PE connection is intact and the
error message still appears, select the "Disable ground check" check box at
the Device Setup tab in the Options view (see ”Device Setup” on page
2-33).
• Ground the isolating transformer outputs on the N (neutral) output or select
the "Disable ground check" check box as described above.
• Instead of supplying CPC 100 from phase - neutral (L1-N, A-N), it may also
be supplied from phase - phase (for example, L1-L2; A-B). However, the
voltage must not exceed 240V AC.
• Fuse-protect the power supply (16 A automatic circuit-breaker).
• Do not use an extension cable on a cable reel to prevent an overheating of
the cord; run out the extension cord.
• Keep extension cables as short as possible to prevent power loss.
DANGER!

Preface

• If the power supply is ≤190V AC, CPC 100 cannot provide the full output
power at the 800A AC output.
The same applies when an external current booster is used. Therefore, in
order to gain the full output power, provide a sufficient power supply
(190V ... 240V AC).
General
• Before connecting or disconnecting test objects and/or cables, turn off
CPC 100 by either the POWER ON/OFF switch or the Emergency Stop
button. Never connect or disconnect a test object while the outputs are
active.
• Make sure that a test object’s terminals that are to be connected to CPC 100
do not carry any voltage potential. During a test, the only power source for a
test object may be CPC 100.
• At their output sockets and especially in the cables connected to them, in
operation the high-current 400A DC and 800A AC outputs generate a
significant amount of heat (approx. 300W/m at 800A). To prevent burns, use
gloves when touching the cables while in operation or a short while after.
• Do not insert objects (for example, screwdrivers, etc.) into any input/output
socket.
• Never use the test cards Quick and Resistance to measure the resistance
of windings with a high inductance because turning off the DC source results
in life-threatening voltage levels.
For this kind of measurement only use the special winding resistance test
card RWinding!
Caution: The connector "Ext. Booster" is always galvanically connected to
mains, regardless whether or not an external booster is selected on
the software tab Options | Device Setup, the green warning
warning light (0) is on, the outputs are turned off or the Emergency
Stop button is pressed.
Handle with extreme caution. Do not use any other booster cables
than the ones supplied by OMICRON.
Note: Even if you switched off CPC 100, wait until the red I/O warning
light is fully extinguished.
As long as this warning light is lit, there is still voltage and/or current
potential on one or more of the outputs.

• When measuring the ratio of voltage and power transformers make sure that
the test voltage is connected to the corresponding primary winding, and the
voltage of the secondary winding is the one that is measured. Accidentally
mixing up the windings can generate life-threatening voltages within the
transformer.
For example: feeding a voltage of 100V/√3 to the secondary winding of a
voltage transformer that has a ratio of 400000V/√3 : 100V/√3, induces a
voltage of 400000V/√3 in the transformer’s primary winding.
• Make sure that when testing a current transformer by feeding a test current
into its primary winding, all secondary windings are shorted. On open
secondary windings, life-threatening voltages can be induced!
DC output to test objects with a high inductance
Use the RWinding (winding resistance) and TRTapCheck (tap changer winding
resistance and on-load tap changer interruption check) test cards only.
As long as the CPC 100 software shows the on-screen message "Switch off in
progress", NEVER connect or disconnect test objects and/or cables.
The message "Switch off in progress" notifies you
that, after CPC 100 was switched off, the
connected external inductance (that is, the test
object) still "feeds" voltage potential back into the
6A DC or 400A DC output.
The existence of this voltage potential at the
6A DC output is also indicated by a lit LED - even
if CPC 100 is switched off.
The CP SA1 (see ”CP SA1” on page 17-14) must be connected to the
CPC 100 V DC input sockets when using the 400A DC output to protect
yourself and CPC 100 from high-voltage hazards.
If a test object with a big inductance was connected to CPC 100, short-out the
test object additionally before disconnecting it from CPC 100.
