16. Remove the four (4) 1/4-20 x 3/4" socket head cap screws, flat
washers and lock washers securing the High Voltage Tank to Gen-
erator Chassis.
17. Carefully lift the High Voltage Tank out of the Generator Chassis.
If the High Voltage Tank is to be shipped, be sure to tighten the
vent screw in the front right corner of the tank.
High Voltage (H.V.) Tank A17 Installation
When installing H.V. Tank A17, keep tank upright at all times. Refer to
Figure 2-10 and 2-11 and proceed as follows:
WARNING! After completing the following proce-
dure, double-check the H.V. Tank wiring connec-
tions to make sure they are correct. Incorrect
wiring can cause damage to the generator.
1. Position H.V. Tanks on H.V. Tank Mounting Brackets so that
mounting holes in H.V. Tank align with those in mounting brack-
ets. Secure tank to brackets using four (4) 1/4-20 x 3/4" socket
head cap screws, flat washers and lock washers.
2. Loosen the vent screw (located in the front right corner of the
tank) two full turns.
3. Connect yellow/green ground wires to H.V. Tank ground stud
(GND) using 8/32 kep nut and fasten securely.
4. Connect H.V. Tank cable PC1 to Power Module A19 lower right
IGBT terminal.
5. Connect H.V. Tank cable PC2 to right terminal on Capacitor C7.
6. Connect H.V. Tank cable PA1 to the left terminal on Capacitor C4.
7. Connect H.V. Tank cable PA2 to Power Module A18 lower left
IGBT terminal.
8. Plug Feedback connector A17P1 (16-pin connector on Cable
Assembly AY51-017) into connector A17J1 on the H.V. Tank and
tighten connector securely.
9. Connect the anode and cathode high-voltage cables to the High
Voltage Tank.
10. Re-install the clear plastic high-voltage protection panel on the
Generator Chassis and re-tighten four (4) mounting screws.
11. Carefully slide the Generator Cover down onto the Generator
Chassis cover screws, taking care not to damage the circuit
