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 High- Power Testing) provides a working framework for establishing safe procedures, but must be read in conjunction with local regulations and accepted codes of practice.

SAFETY TERMS AND SYMBOLS The following safety symbols appear on the equipment: CAUTION/WARNING – Refer to manual DANGER – High voltage Mains off Mains on The following safety symbols appear in this manual: This action or procedure may be dangerous if not carried CAUTION out correctly, and may cause damage to the equipment or connected equipment.
DESCRIPTION OF EQUIPMENT Electrical Specification 1.1.1 Supply Requirements KV5-100 mk2 115/230V 10% 600VA max KV3-250 mk2 115/230V 10% 900VA max KV4-300 mk2 230V 10% 1400VA max KV5-200 mk2 230V 10% 1100VA max 1.1.2 Output Specifications The output voltage, current and duty cycle are as follows:...
The equipment is provided with the following metering ranges using analogue moving coil meters: Metering Ranges Unit Voltage Current High KV5-100 mk2 10mA 100mA KV3-250 mk2 1.6kV 3.2kV 30mA 300mA KV5-200 mk2 20mA 200mA The ranges on both instruments are selected by means of switches located on the front panel.
Fault Burn Facility (except KV5-200 mk2) The KV5-100 mk2, KV3-250 mk2 and KV4-300 mk2 are provided with an internal current limit circuit which limits the output current from the unit under short circuit conditions. This can be used to “burn” faults.
Timer Operation (KV5-100T mk2 only) The KV5-100T mk2 is fitted with a 5 second-5 min test duration timer. The test timer has two controls; ‘Select Test Time’ and ‘Alarm Cancel’. The timer has nine switch-selectable ranges of 5, 10, 15, 20, and 30 seconds and 1, 2, 3 and 5 minutes. There is an ‘OFF’ position for when the timer operation is not required.
OPERATION Safety The outputs from all units in the range are very dangerous, and if used incorrectly could be fatal. The unit must only be installed, operated, and maintained by suitably qualified and trained personnel. It is essential to follow accepted safety procedures and local health and safety regulations and guidelines when installing and operating high voltage equipment.

Method of Operation 2.3.1 Connections Before making any connections please ensure that you are aware of all hazards relating to the system and environment in which it is operating. Ensure that the key switch is in the off position and the key is removed before making any connections.
MAINTENANCE Maintenance and repair of the KV5-100 mk2 series must only be carried out by suitably qualified and trained personnel. Potentially lethal voltages are present inside the unit and on the output leads. Ensure that the unit is disconnected from the mains before removing WARNING any covers.
OVERALL PERFORMANCE SPECIFICATION Insulation resistance at 500V DC: >10 megohms between mains input and frame. Applied voltage test: 2.0kV RMS for 1 minute between mains input and frame. Accuracy of instruments kV meter: ±1.5% of FSD mA meter: ±2.5% of FSD Instrument calibration is traceable to national standards.
