Page 12: Electrical Specification
1.2.4 External Interlock The KV30-40D mk3 and KV15-80D mk3 is fitted with a 24Vdc external interlock socket. This interlock prevents the output being energised unless an external circuit is closed. The interlock circuit may also be used to connect normally closed emergency off switches to the unit wired in series with any interlock switches. -
Page 13: Output Voltage Control
Output Voltage Control The output is controlled from zero by means of a regulating transformer. The transformer is operated by means of a control knob which is located on the front panel. To increase the output voltage the knob is turned in a clockwise direction. Overload Protection The equipment is fitted with fixed and variable overload protection circuits as standard. -

Page 15: Operation
OPERATION Safety The outputs from the KV30-40D mk3 and KV15-80D mk3 are extremely dangerous, and if used incorrectly could be fatal. The unit must only be installed, operated, and maintained by suitably qualified and trained (skilled) personnel. It is essential to follow accepted safety procedures, and local health and safety regulations and guidelines when installing and operating high voltage equipment. - Page 16 An interlock should be considered to be a safety back-up feature. An interlock should not be regarded as a substitute for adequate safety rules and proper operator vigilance. 2.1.2.2 Grounding of the high voltage output A temporary ground should be applied to the high voltage output when the circuit has been de- energised using the earth stick provided.
