76 Neut Wht
Notes: 1X1 designates connector on rear of power supply. Lug numbers designate wire numbers on end of Interface cable.
* These functions are available only on MAX200s equipped with Torch Height Control option.
** Note that resistor R150 and capacitor C78 are connected in series across the contacts. In some cases one lead of
R150 must be cut from the control PC board as the R-C circuit may provide enough current flow to maintain machine
motion input to cutting machine.
*** Note that resistor R155 and capacitor C79 are connected in series across the contacts. In some cases one lead of
R155 must be cut from the control PC board as the R-C circuit may provide enough current flow to maintain machine
motion input to cutting machine.
