Equipment List
The EIK CW power supply is shipped with:
- a rack mountable Power Supply Unit
- a remote connection and mounting (with connecting cable) Unit
- an installation and operating instructions manual
Unpacking
Remove and identify all items listed on the equipment list from the shipping container. Retain all packing material for future EIK CW power supply transportation.
Caution; the rack mounted power supply weighs approximately 80 pounds and may require two person lifting.
Mounting
The Power Supply Unit is designed to be mounted into a standard 19" rack. It is recommended that additional support of the module (side rails) be used due to the weight of the unit. During operation, the power supply may assume any orientation that maintains air-cooling to the rear inlet and outlet ports.
The EIK may be mounted in any orientation within the Remote Connector Unit lead lengths.
Cooling
EIKs and their CW power supplies are conduction, air, or liquid-cooled. All applications must use exhaust side flow interlocks to prevent or remove operation if the cooling system is compromised. Interlocking capability is available on either the Remote Connector Unit ("EIK OVER TEMP") or directly at J2.
Liquid-cooled EIKs must use clean deionized coolant. The specified flow rate is for water and must be increased for lower heat capacity fluids. Depressed voltage collectors must use and maintain a deionized coolant with a minimum of 1 M? cm resistivity.
Caution; all metal components of the liquid-cooling system (except the EIK collector) must be grounded to prevent charge accumulation (potentially collector-to-body voltage) through the coolant, posing an operator hazard.
Connections
Grounding
Ground both the Power Supply Unit and the Remote Connection Unit to safety grounds at the rear grounding studs.
Caution; do not rely on electrical connectors to fulfill grounding connections.
Prime Power Connections
Prime power is applied to J4 (if used or a line cord) using the following pin assignments:
- Pin A - 220 ±5% Vac, 48 – 62 Hz, 1 phase (wrt to pin C) (or neutral)
- Pin B - no connection
- Pin C - 220 ±5% Vac, 48 – 62 Hz, 1 phase (wrt to pin A)
- Pin D - ground
User supplied prime power must be externally fused for product protection. See the Specifications section for operating / fusing current requirements.
EIK Electrical Connections
The electrical lead connections to the EIK are color coded as follows:
YELLOW - HEATER(-ve)
WHITE - CATHODE & HEATER (+ve)
RED - ANODE
BLUE - COLLECTOR
BROWN - BODY (may be BLACK in some applications)
High voltage leads should be kept away from ground planes to reduce the possibility of corona. Keep the leads as short as possible. Restrict personnel access to unshielded leads.
High voltage connections to the EIK are made through flying leads, which may be connected to the binding posts of the Remote Connector Unit. Refer the the applicable EIK Final Test Results for correct collector voltage connection (either virtual ground or 25% voltage depression) and anode connection (either Divided Anode or Regulated Anode). Within the Remote Connection Unit, dress and secure low voltage leads away from the high voltage terminals.
Remote Connector Unit
The Remote Connector Unit is connected to the Power Supply Unit through plugs P2 and P3 connected to jacks J2 and J3.
Caution; high voltage connector J3 is an air exclusion type connector which requires repeated "wiggling" while turning the locking ring. Inadequate tightening may result in unrepairable damage due to an arc internal to the connector.
Caution; keep the high voltage connectors covered when not in use.
If the user makes direct connections to J3, take appropriate safety precautions with personnel shielding.
Control and Monitoring
EIK interlock functions are available at J2 and within the Remote Connection Unit. A cooling system interlock must be employed to protect the EIK from operation with inadequate cooling (see Figure 2 – Remote Unit Connections).
All control and monitoring functions may be implemented through the RS-422/RS-485 connector on the rear of the Power Supply Unit.
