Connect terminals AUX-AC H and L of terminal block BT04 on the
main power supply to the color CRT power supply terminals AC H and
AC L, which are located on the rear of the color operator panel, using the
power supply cable C03.
Important: The chassis ground terminal connects to the operator panel
chassis and designated cable shields. Power supply common is AC
coupled to chassis ground. It is the user’s responsibility to determine if a
direct connection to cabinet ground bus is required.
