4. Remove the power supply.
Remove the AC power harness
Note
Before you begin, remove the following as described in this manual:
• Battery
• Rear housing
• Power supply
Disconnect the AC power harness from the IEC connector and grounding plate.
Reassembly notes
When replacing the rear case or AC power harness, route the wiring as follows:
• Connect blue to neutral (N), green to ground (GND), and brown to line (L).
Note
Note
Do not disconnect the AC power harness from the IEC connector unless
you are replacing it. Once you disconnect the AC power harness, you
cannot reuse it.
N
GND
L
The power supply harness to IEC connector is rated for a single
connection. Replace the power supply harness if it has been disconnected
from the IEC connector.
In older devices, color coding of the line and neutral wires was reversed.
The color of the wiring has no impact on the functionality of the device and
does not require reversing the connection to the IEC connector. Reversing
the connection to the IEC harness would also require replacement of the
power harness.
The risk of not replacing the harness is considered minimal as the manual
contains a warning to disconnect the device from AC power before
opening the case.
