3.4.4 SYSTEM INTERCONNECTION
Turn OFF all front and rear panel circuit breakers.
Connect the bottom ground stud on the rear panel of the HVPS chassis to a common
ground on the vacuum system. See Figure 3-4 for Grounding information, wire gauges,
and connections. This vacuum system ground must be the common point of all ground
connections.
Ground the ST Controller directly to the top HVPS ground stud.
Connect the supplied 25pin Sub-D M-M cable between J1 on the HVPS and J1 on the
Controller.
Connect the supplied 25pin Sub-D F-F cable between J2 on the HVPS and J2 on the
Controller.
Connect the supplied 15 pin Sub-D M-F cable between J3 on the HVPS and J3 on the
Controller.
Connect the supplied HV Output cable (RG Coax) between J4 on the HVPS and J4 on
the supplied Filament Output Transformer (see Figure 3-5). It is good practice to keep
the HV cable away from sharp objects, machinery, and high traffic areas. This will
minimize the possibility of damage to the cable.
Connect the supplied Filament Power cable between J7 on the HVPS and J7 on the
Filament Output Transformer (see Figure 3-5).
The ends of the red HV cables need to be custom configured to connect to the High
Voltage Feedthroughs for the E-Beam Source.
DO NOT SEPARATE the pair of red cables except at the connecting ends, keep these
separations as short as possible.
Connect the safety interlocks to J6 of the ST controller as described in Chapter 3.6
according to the connection diagrams in Figure 9-1(208V) or Figure 9-2(400V).
With input AC line voltage OFF, and a lockout/tag out in place, terminate the AC line
feed wires with the supplied terminals (P/N 124-1440-1), connector shell (P/N 124-
1441-1), and cable clamp (P/N 124-1442-1). It is mandatory to use 600V insulated,
stranded wire of sufficient gauge (10AWG (6mm²) for 208VAC, 12AWG (4mm²) for
400VAC). Strip about 0.4 inch (~10mm) of insulation from the wires before crimping
them to the terminals. Refer to the pinout in Chapter 3.4.5 for proper insertion
connections.
Connect the completed connector assembly to J8 on the HVPS.
