Safety instructions
1 Safety instructions
1.1 Operator qualifications
Working on high-voltage assets can be extremely dangerous. Testing with the CP TD1 must 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 CP TD1 must be under
constant supervision of an experienced operator while working with the equipment. The operator is
responsible for the safety requirements during the whole test.
1.2 Safety standards and rules
1.2.1 Safety standards
Testing with CP TD1 must comply with the internal safety instructions and additional safety-relevant
documents.
In addition, observe the following safety standards, if applicable:
• EN 50191 (VDE 0104) "Erection and Operation of Electrical Test Equipment"
• EN 50110-1 (VDE 0105 Part 100) "Operation of Electrical Installations"
• IEEE 510 "IEEE Recommended Practices for Safety in High-Voltage and High-Power Testing"
Moreover, observe all applicable regulations for accident prevention in the country and at the site of
operation.
Before operating the CP TD1 and its accessories, read the safety instructions in this User Manual
carefully.
Do not turn on the CP TD1 and do not operate the CP TD1 without understanding the safety information
in this manual. If you do not understand some safety instructions, contact OMICRON before proceeding.
Maintenance and repair of the CP TD1 and its accessories is only permitted by qualified experts at
OMICRON Service Centers (see "Support" on page 69).
1.2.2 Safety rules
Always observe the five safety rules:
► Disconnect completely.
► Secure against re-connection.
► Verify that the installation is dead.
► Carry out grounding and short-circuiting.
► Provide protection against adjacent live parts.
