PWB assembly Sensor

Pass this through a notch of the 
PWB holder.

Install the PWB assembly Sensor upon completion of the work shown below.

Affix TAP3 after checking connection of E950 
connector (so that it will not come off).

CNPOW

CNTH

When connecting the CNPWR connector to the CN1 
connector, make sure they are completely locked.

Let the CNPOW and TSW cables cross each other 
(so that the TSW will not approach the primary side 
power circuit).

Connect CNTH to E950 connector of PWB 
assembly Sensor
