Please read these instructions carefully before beginning the assembly. Failure to understand and
follow assembly instructions may result in injury to technician and/or end user and may void the
warranty. If you have any questions call Sunrise Medical Technical Support at [phone].
Before beginning the PCB replacement,
ensure you heed the following warnings.
WARNING
Minimal electronics experience is required to
complete Shroud Replacement.
WARNING
Ensure your work surface is free of any build
up of liquids and/or static electricity. Touch a
metal surface to bleed off static electricity
prior to touching the PCB (Printed Circuit
Board).
WARNING
Keep the new PCB in the ESD (Electrostatic
Discharge) protective packaging bag until it is
ready to install.
WARNING
Limit touching of the PCB to outer edges
with as light a touch as possible, minimizing
pressure on the PCB.
WARNING
If the PCB must remain outside of the
enclosure, place it in a static protective bag
until ready for reassembly.
WARNING
Attach the ground cord from the ESD Field
Kit to the uncoated metal shown in Figure 1.
Follow all instructions provided in the ESD Field
Kit to ensure not to damage the PCB.
1. To remove skid plate (B), use an M2 Allen
wrench to remove screws (A). (Fig. 1)
2. To remove battery plate hardware, use
a T-20 t-handle to remove torx screws (C)
and loosen the battery plate (Fig. 2)
3. To loosen PCB mounting hardware, use a
T-15 t-handle to loosen screw (D). (Fig 3)
4. To remove hardware on side of shroud,
use a T-20 t-handle to remove screws (E).
(Fig. 4)
5. To remove hardware on front of shroud,
use a M4 Allen wrench to remove
socket head screws (F). (Fig. 5)
6. To remove the left shroud, disconnect the
charger port harness (G). Then, remove
the shroud. (Fig. 6)

7. To remove the PCB (K) from the
right shroud, loosen the screw (L).
(Fig. 7)
Note: for reassembly, ensure
screw is aligned with PCB
mounting hole.
8. Disconnect the connectors from
the top of the PCB (Fig 8). Pull
the 9-Pin connector from the
motor (Fig 9) through the right
shroud before disconnecting.
Ensure the motor harness stays on
the outside until the new PCB is
connected.
9. Disconnect the connectors (I)
from the bottom of the PCB
(Fig 9), and remove the battery
plate (J). (Fig. 7)
10. Note the orientation of the PCB
shown in Figure 8 and 9 before
installing the new PCB. Incorrect
installation will result in damage
to the PCB. Connect the motor
connector from the new PCB
first. Push the motor connector
back through the hole in the right
shroud.
11. Connect the connectors on the
top of the PCB (Fig. 8). Connect
the connectors from the battery
plate (J) to the bottom of the
PCB (Fig. 9). Re-connect the
connector from the charger port
(G) (Fig. 6) to the battery plate
(J).
12. Complete reassembly by
following steps 1-8 in reverse.
