Removing Power Sensor Shell

Disassembly Procedure

Disassemble the power sensor by performing the following steps:

CAUTION:

Disassemble the power sensor only in a static free workstation. Electrostatic
discharge will render the power sensor inoperative.

1

At the rear of the power sensor, insert the blade of a screwdriver between the plas-
tic shells (Figure 4). To prevent damage to the plastic shells use a screwdriver
blade as wide as the slot between the two shells.

2

Pry alternately at both sides of the connector J1 until the plastic shells are apart.
Remove the shells and the magnetic shields.

Reassembly Procedure

1

Replace the magnetic shields and the plastic shells as shown in Figure 3. Snap the
plastic shells together.
