4mm² for 208VAC,
min. #14AWG / 2.5mm² for 400VAC). Strip about 0.4 inch (~10mm) of insulation from the
wires before crimping them to the terminals.
Connect the completed connector assembly to J6 POWER IN on the HVPS.
TT-10/15/20: With input AC line voltage OFF, terminate the AC line feed wires with
ferrules. It is mandatory to use 600V insulated stranded wire of sufficient gauge (min.
#10AWG / 6mm² for 208VAC, min. #12AWG / 4mm² for 400VAC; except for TT-15
208VAC: min. #8AWG / 10mm²).
Strip about 0.4 inch (~10mm) of insulation from the wires before crimping them to the
ferrules. Connect the completed cable to the terminal block at the rear of the HVPS
cabinet and tighten the strain relief.
9. Connect the safety interlocks to J7 INTERLOCKS of the controller as described on page
20 and in section 6, Figures 6-A through 6-E.
10. Install the two supplied ¾" NPT flexible Strain Relieves 110-0052-4 in the openings of the
Filament Transformer Box, run the supplied red HV Cable Set 122-0031-1 through them,
connect the ring lugs to the output bolts of the Filament Transformer (see Figure 4-J),
and connect the shields to the internal GND bolt. Keep the shield wires away from the
HV.
The other ends need to be custom configured to connect to the High Voltage
Feedthroughs for the E-Beam Source. Make sure to strip back the shield by at least 2"
(50mm) and keep it away from the hot conductor.
11. When all connections have been double checked, apply AC power from the AC line input
and turn both rear panel circuit breakers ON. The unit is now ready for operation.
