1 Safety Pre autions
The following safety precautions ust be observed during all phases of operation, service and
repair of this instru ent. By purchasing this equip ent the purchaser assu es all liability for the
operation and use of this equip ent. The intended use of the instru ent, its design and
anufacture, is to be conducted within the precautions or other specific warnings located within
this anual. Failure to co ply with these precautions and other specific warnings violates the
safety standards of design, anufacture, and intended use. Raytech assu es no liability for the
operation and use of this equip ent.
1.1 Safe operation
Only qualified, knowledgeable persons should be per itted to or atte pt to operate this test
equip ent. All test personnel should fully fa iliarize the selves with the correct application and
operation of this and all test equip ent prior to operation. Persons directly and indirectly engaged
in the operation of this test equip ent should keep clear of all high voltage apparatus while
conducting tests and easure ents.
1.2 Ground the Instrument
To ini ize shock hazard, the Ground Ter inal on the instru ent ust be properly connected to
an Earth grounded point. In any cases, the quality of the safety ground ter inal provided by the
power cord does not fulfil the safety require ents.
Also the power cord supplied with the equip ent ust be connected to an electrical receptacle
with an electrical ground (safety earth ground).
90315-1.2 Instruction Manual CAPO Page 6 of 117
WARNING !
WARNING !
Never connect the Instru ent to an energized Transfor er!
WARNING !
WARNING !
Non-grounded Instru ents are dangerous and ay cause da age to
personnel and to the Instru ent.

1.3 Operator qualifi ations and safety standards
Before perfor ing any test with this instru ent, read this user anual and observe all safety
precautions indicated.
Be aware that Safety is the responsibility of the user!
Corrective aintenance ust be perfor ed by qualified personnel who are fa iliar with the
construction and operation of the test set and the hazards involved.
Raytech AG refuses to accept any responsibility for consequential or direct da age to persons or
goods due to non-observance of instructions contained herein or due to incorrect use of the
instru ent.
Never disconnect the high voltage or the low voltage test cables fro either the ter inals of the
test speci en or the instru ental side, unless the CAPO is in safe ode.
The CAPO and the object to which it is connected are possible sources of high voltage electrical
energy and all persons aking or assisting in tests ust use all practical safety precautions to
prevent contact with energized parts of the test set and related circuits. Persons actually engaged
in the test ust stand clear of all parts of the co plete high voltage circuit, including all
connections, unless the test set is deenergized and all parts of the test circuit are grounded.

HIGH VOLTAGE !
HIGH VOLTAGE !
Hazardous voltage ay result in severe injury or death!
CAUTION !
CAUTION !
The FIRST cable you have to connect to earth ground is always the Safety
GND. This is also the LAST cable to disconnect! Any interruption of the
grounding connection can create an electric shock hazard.

Working on HV devices is extre ely dangerous. Measure ents ust be carried out only by
qualified, skilled and authorized personnel. Before starting to work, clearly establish the
responsibilities. Personnel receiving training, instructions, directions or education on the
easure ent setup ust be under constant supervision of an experienced operator while working
with the equip ent. The easure ent ust co ply wit the relevant national and international
safety standards listed below:
•EN 50191 (VDE 0104) “Erection and Operation of Electrical Equip ent”
•EN 50110-1 (VDE 0105 Part 100) “Operation of Electrical Installations”
•IEEE 510 “Reco ended Practices for Safety in High-Voltage and High-Power Testing”
•LAPG 1710.6 NASA “Electrical Safety”
Moreover, additional relevant laws and internal safety standards have to be followed.
1.4 Measuring able management and onne tion
The HV Cable and the 2 easure ent cables A and B are shielded. On the one hand because of
the safety and on the other because of the easuring accuracy.
Take care that no jacket of the cable touches the high voltage parts because of partial discharge or
flashover!
1.5 Before applying power
Read this anual carefully before operating the syste . The CAPO 2.5 and the CAPO 12 operates
within a wide range of power input fro 85Vac to 264Vac and 47Hz to 63Hz with auto atic
ranging.

WARNING !
WARNING !
Before operating the instru ent, be sure you have read and understood fully
the operating instructions. This instru ent is connected to hazardous
voltages. It is the responsibility of the user to ensure that the syste is
operated in a safe anner.
One ust always expect that under certain circu stances a dangerous high
voltage can be applied!
CAUTION !
CAUTION !
Note that no cable touches the high voltage parts with the jacket!

1.6 Keep away from live ir uits
Operating personnel ust not re ove instru ent covers. Co ponent replace ent and internal
repairs ust be ade by qualified service personnel. Do not replace co ponents or service this
instru ent with the power cable connected. To avoid injuries, always discharge circuits, disconnect
power and re ove external voltage sources before touching co ponents.
1.7 Do not operate in an explosive atmosphere
Do not operate the instru ent in the presence of fla able gases or fu es.
1.8 Do not substitute parts or modify Instrument
Because of the danger of introducing additional hazards, do not install substitute parts or perfor
any unauthorized odification to the instru ent. Return the instru ent to a Raytech service
depart ent for service to ensure proper operation and that safety features are aintained.
Instru ents, which appear da aged or defective, should be ade inoperative and secured against
unintended operation until they can be repaired by qualified service personnel.
1.9 Transportation and Lifting
Especially the CAPO 12 is a heavy instru ent. Do not lift it alone. It is equipped with wheels for
easy transport.
