EIK sub-system installations must provide protection to personnel as described below. In addition, to protect the EIK and it's associated power supplies, the installation and operating precautions must be observed and absolute ratings must not be exceeded.

Personnel

High Voltage

Caution; voltages required for the operations of EIKs, can be dangerous and potentially fatal to personnel. Equipment should be designed with protective interlock circuits on access panels to prevent accidental contact with high voltage. Some EIK collector designs operate at depressed voltage potential. Forced air-cooled systems must accommodate these depressed voltages with insulated and shielded ducting. Liquid-cooled depressed voltage collectors use plastic coolant tubing for electrical isolation; but, all metal components in the cooling system must be grounded to prevent charge transfer through the coolant.

Microwave Radiation

Caution; prevent the exposure of personnel to millimeter wave radiation from any EIK equipment waveguide circuits. EIKs have specified RF load requirements to prevent oscillation; never operate with unterminated waveguides.

EIK millimeter wave waveguide circuits employ high power density RF that may radiate from any waveguide flange gaps. Refer to "American National Standard Safe Levels of Microwave Radiation" (ANSI C95.1 published by IEEE, 345 East 47th Street, New York, NY, 10017) for safe radiation levels.

Equipment

Grounding

Ensure that all components of the EIK sub-system are suitably grounded. While every effort has been made to ensure adequate electrode spacings within the EIK and it's CW power supply, occasional electrical breakdowns are possible. Arc currents can be very large in value and induce undesirable voltage drops in marginal ground leads. Do not rely on ground connections through removable connectors.

The EIK leads are not ground shielded and therefore personnel barriers should be utilized.

Approved Operation

Caution; never operate the EIK sub-system with any of the connectors not connected; irreparable damage may result.

The prime power applied to J1 must be within voltage ratings and fused to prevent a fire hazard; see Specifications for fuse ratings.

Servicing, maintenance, or repairs must be performed by high voltage qualified personnel.

Interlock System

Caution; interlocks should be incorporated into the CW power supply to prevent or remove any high voltage or safety hazard if any of the EIK sub-system absolute ratings are exceeded. Do not rely on electrical interlocks for human safety.

A cooling system interlock must be used to prevent possible damage to the EIK under inadequate cooling conditions (use "EIK OVER TEMP" interlock).
