Page 8: Installation
INSTALLATION SAFETY PRECAUTIONS DANGER – HIGH VOLTAGE High, potentially lethal, voltage is present within this equipment and at end of the high voltage cable. Great care must always be exercised when working with this equipment. Only qualified and properly trained personnel may test or work with this equipment. - Page 9 66″ will impair the Power Supply’s function. Only use the ribbon cable supplied by Niles Electronics Inc. This cable carries both analogue and digital signals. Using different type of cable may cause "crosstalk" among the conductors. The signal crosstalk can...

Page 10: Rack Asswmbly
RACK ASSEMBLY NOTE: All NE, NEU and NEDG series are using the same rack. Even though the pictures may not show exactly the model you purchased, the assembly procedures are the same. NOTE: Leaving the bolts slightly loose until all of the bolts are in position will make minor adjustments easier to make. - Page 11 4. Line up the two bottom holes in the front panel to the holes in BRKT-P2. Screw in two ½″ bolts with nylon washers, attaching these two pieces together. 5. Place the Power Module to the right of the HV Module so that it is lined up in the FRONT, RIGHT corner of the two bottom pieces.
- Page 12 8. Place BRKT-EAR-L to the left of the HV module with the six FEX nuts lined up with the holes in BRKT-P2 and BRKT-P3. The slanted edge should be going downwards towards the back, and the front flap should bend to the left away from the modules.
- Page 13 The Completed Rack - 1 The Completed Rack - 2 Once assembled, the Rack Assembly will fit easily into a standard 19″ rack. It is designed with the ease of Module removal in mind. To remove a Module, simply remove the four front bolts...

Page 14: Cable Connections Between Modules
The connections are also labeled on the back panels of the Modules. FILAMENT TRANSFORMER CONNECTION Niles Electronics Inc. accommodates a filament transformer, since April 2005, with each power supply. The filament resistance, at room temperature, should not be less than 5 mOhms (5 thousandth Ohms). -
Page 15: High Voltage Cable Connection
resistance is corrected or the short-circuit of filament block is resolved. Should any customer have questions regarding this issue, please do not hesitate to contact Niles Electronics Inc. The core of the Filament Transformer must be connected to the Tank ground. It is advisable to remove the paint/varnish from a small area around the mounting holes of the Transformer and the frame. -

INTERLOCK CONNECTIONS D-SUB 15 RIBBON CABLE CONNECTOR CONDUCTOR PIN NO. SOURCE INTERLOCK INTERLOCKS The external interlocks are connected to the Power Supply and their installation is described below. WARNING All statements pertaining to operator and equipment safety apply only if the external interlocks are installed as specified below and only if the operator does not disable the safety features, inherent in the interlocks, by bypassing the switches. -
Page 18: High Voltage Interlocks
HIGH VOLTAGE INTERLOCKS The E-Beam Gun Power Supply has two groups of interlock connections: one for the High Voltage and another for the Emission Current (Source Current). The High Voltage has the following interlocks: AIR VACUUM TANK ... -
Page 19: Fuse
The interlocks for the Emission Current are: FUSE HVAC WATER AUX 2 FUSE: This fuse is in series with the Filament Transformer Primary Winding. If the Filament Transformer is overloaded, the fuse will be burnt and its LED indicator will turn off. However, if the LED indicator is off, the Fuse is not necessarily burnt as there is a Surge Current Sensor Circuitry that can also turn off this LED indicator. -

This is where the two jumpers are located at the time of shipment from Niles Electronics. Moving the jumpers so that each contacts a center pin and a pin closest to the label “R78” on the other side of the 6-pin DIP Header will give the user the option of adjusting the high voltage from the Remote Control Unit when the Remote is selected.

Page 26: Power Module
POWER MODULE SWITCHES: There are two Magnetic Hydraulic Circuit Breakers. One for control electricity while another for power electricity. Flipping them upwards will turn electricity and their pilot lights on. Flipping them downwards turns electricity and their pilot lights off. PILOT LIGHTS: There are four Pilot Lights. -
Page 27: High Voltage Module
HIGH VOLTAGE MODULE There are no controls that can be touched on the front panel of the High Voltage Module. The output connection is to be made on the back panel. Please note that the NE-4 and the NE-6 models have different power ratings (4 KW and 6 KW, respectively) but are otherwise identical in outward appearance and in operation of these modules. -
Page 28: Control Module
CONTROL MODULE FUNCTIONS The front panel of the Control Module consists of four distinct functions that are clearly labeled at the top of each section. They are, from left to right: MAIN POWER HIGH VOLTAGE OUTPUT POWER & CONTROL SOURCE ... - Page 29 HIGH VOLTAGE: The High Voltage Interlock Indicator Lights, from left to right, are: AIR: Temperature inside HV Module VAC: Vacuum TANK: Tank High Voltage Access AUX 1: Auxiliary External Interlocks The Interlock LED Indicators (Air, VAC, Tank, Aux 1) light when the conditions these LEDs reflect are correct for operation of the system.
