GENERAL SAFETY STATEMENT

The following safety precautions should be reviewed to avoid injury to the user and damage to

the product (and other products connected to it). To avoid potential hazards only use this
product as specified.

Only suitably qualified personnel should use this equipment. Servicing of this

product should only be carried out by suitably qualified service personnel.

The high voltage generated by this unit is extremely dangerous and may be fatal.
This unit is designed for operation in a designated high voltage test area.

To Avoid Fire Hazards and Personal Injury

Use the correct power supply lead. Only use a suitably rated and approved power supply

lead for the country of use.
Ensure that systems that the unit is to be connected to are dead.
Do not connect and disconnect leads whilst outputs are switched on.
Ensure that the product is grounded. To avoid electric shock it is essential that the

grounding conductor is connected to the earth ground. An additional earth terminal is

provided on the unit for connection to a local earth if necessary. Ensure that the unit is

properly grounded before making any connections to inputs or outputs.
Output ratings must be observed to prevent fire hazards and risk of injury to the operator.

Consult the product manual for ratings information before making any connections to the

unit.
It is ESSENTIAL to consult the product manual for rating information before making any

connection to a terminal or terminal group marked with a warning triangle.
Only use fuses of a type and rating specified for this product.
Do not operate the unit out of its case or with any covers or panels removed.
Do not touch exposed connections and components when power is present.
Do not operate the product if any damage is suspected. Refer the unit to qualified service

personnel to be checked.
Do not operate the unit in wet or damp conditions
Do not operate the unit in an explosive atmosphere
This unit is not designed for unattended operation

If any further queries occur regarding the usage and maintenance of
the equipment detailed in this manual, please refer these to the
supplier of the equipment in the first case or to:

HIGH VOLTAGE SAFETY

It is essential to follow safe working procedures when working with high voltage. Information
on accepted codes of practice should be obtained from your local heath and safety regulatory
body.

IEEE standard 510-1983 (IEEE Recommended Practices for Safety in High-Voltage and High­Power Testing) provides a working framework for establishing safe procedures, but must be
read in conjunction with local regulations and accepted codes of practice.

The following excerpts are taken from IEEE 510

All ungrounded terminals of the test equipment or apparatus under test should be

considered as energised.

Common ground connections should be solidly connected to both the test set and the test

specimen. As a minimum, the current capacity of the ground leads should exceed that
necessary to carry the maximum possible ground current. The effect of ground potential
rise due to the resistance and reactance of the earth connection should be considered.

Precautions should be taken to prevent accidental contact of live terminals by personnel,

either by shielding the live terminals or by providing barriers around the area.
The circuit should include instrumentation for indicating the test voltages.
Appropriate switching and, where appropriate, an observer should be provided for the

immediate de-energisation of test circuits for safety purposes. In the case of dc tests,

provisions for discharging and grounding charged terminals and supporting insulation

should also be included.
High-voltage and high-power tests should be performed and supervised by qualified

personnel.
Consideration should be given to safety regulations which may apply to specific

circumstances; for example, HSE, company, or government regulations.

In the use of signal-gathering equipment, each device should be used in such a manner that it
will not present a personnel hazard should it inadvertently become a part of the high-voltage
circuit, or fail to function properly.
