Subtask 23-73-41-020-052-A ** ON A/C NOT FOR ALL
A. Removal of the Passenger Interface and Supply Adapter (PISA) with audio function and the Passenger Call Switches
(1) Open the Passenger Service Unit (PSU).
(a) Remove the section hose (1) from one side of the mounting rail (2).
(b) Pull and lower the related PSU (3).
(b) Put identification on the electrical connectors (7) and carefully disconnect them from the Printed Circuit Board (PCB) of the PISA (8).
(c) Put the CAP-BLANKING on each disconnected electrical connector and receptacle.
(e) Put the PISA (8) into a BAG - ANTISTATIC.
(3) Remove the Passenger Call Switch.
(b) Hold the horizontal PCB with the Passenger Call Switch on it (9) on its sides and remove it from the PSU (3).
(c) Put the PCB (9) into a BAG - ANTISTATIC.
Subtask 23-73-41-020-053-A ** ON A/C NOT FOR ALL (1) Open the Passenger Service Unit (PSU).
(a) Remove the section hose (1) from one side of the mounting rail (2).
(b) Pull and lower the related PSU (3).
CAUTION:
OBEY THESE PRECAUTIONS TO PREVENT ELECTROSTATIC DISCHARGE (ESD) DAMAGE TO THE COMPONENTS:
- STAY ON A CONDUCTIVE SURFACE THAT IS ELECTRICALLY GROUNDED.
- USE A CONDUCTIVE WRIST-STRAP THAT IS ELECTRICALLY GROUNDED. (CONNECTED TO A BONDING-POINT NEAR THE WORK AREA).
- BEFORE YOU USE THE TOOLS, MOMENTARILY HOLD THEM AGAINST AN ELECTRICAL GROUND TO RELEASE STATIC ELECTRICITY.
CAUTION:
BE CAREFUL WHEN YOU REMOVE OR INSTALL A PRINTED CIRCUIT BOARD. DO NOT TOUCH IT DIRECTLY. IT IS EASY TO CAUSE DAMAGE TO THIS COMPONENT.
(2) Remove the PISA. NOTE: Be careful when you work on the lowered PSU. If you use too much force, it is easy to move the PSU in the mounting rail too much. This can cause damage to the hinge in the mounting rail.
CAUTION:
MAKE MATCH MARKS ON ALL THE ELECTRICAL WIRES BEFORE YOU DISCONNECT THEM. INCORRECT CONNECTION OF WIRES WILL CAUSE DAMAGE TO EQUIPMENT.
(a) Carefully release the latches (5), then carefully lift the cover (4) and remove it. (b) Put identification on the electrical connectors (7) and carefully disconnect them from the Printed Circuit Board (PCB) of the PISA (8).
(c) Put the CAP-BLANKING on each disconnected electrical connector and receptacle.
NOTE: Touch the edges of the PISA (8) to lift it. Try not to touch the PCB directly.
(d) Carefully release the latches (6) of the PSU (3) and carefully lift the PISA (8) from the PSU (3). (e) Put the PISA (8) into a BAG - ANTISTATIC.
(3) Remove the Passenger Call Switch.
CAUTION:
BE CAREFUL WHEN YOU REMOVE OR INSTALL A PRINTED CIRCUIT BOARD. DO NOT TOUCH IT DIRECTLY. IT IS EASY TO CAUSE DAMAGE TO THIS COMPONENT.
(a) Carefully release the latches (10) of the PSU (3). (b) Hold the horizontal PCB with the Passenger Call Switch on it (9) on its sides and remove it from the PSU (3).
(c) Put the PCB (9) into a BAG - ANTISTATIC.
B. Removal of the Passenger Interface and Supply Adapter (PISA) without audio function and the Passenger Call Switches
