1. Switch off power to the Islander and disconnect all AC power to the unit. Remove the screws that secure the side
covers on the pedestal and remove the covers. Switch off AC and battery power on the PCU power supply.
2. Install the C06593 Relay Control Cable. This
cable has four connectors in graduated
lengths. On the left side of the pedestal,
start with the longest of the four connectors
and attach it to the rightmost square opening
in the support bracket so that the pins are
pointing away from the center of the
pedestal. Repeat for all connectors from
longest to shortest. Run the cable between
the two support brackets to the card cage
side. See drawing at right.
3. Install the C06594 relay module assemblies. Connect the cables to the relay control cable installed in Step 2. Apply
the numbers from the C02952 decal to the relay modules. Numbering is 5 6 7 8 from left to right.
4. Install the C06600 card cage assembly using the three C04037 screws, 067126 washers, and 068842 locking washers.
Connect the relay control cable 12-pin connector to P2 of the motherboard in the card cage assembly.
5. Remove cover from the power supply. Remove the DC power cable that connects P1 of the power supply to P1 of the
motherboard on the existing PCU card cage. Install the C06590 DC power cable. Connect the cable from P1 of the
power supply to P1 of the existing PCU card cage and P1 of the newly installed card cage. Replace power supply
cover.
6. On the new PCU CPU board, set the address switches to match to site’s configuration. Set the jumpers on the new
Pump I/O board to match the pulsers being used. Refer to the Islander II Installation Manual C35963. Install the
C32731 escutcheon plate using the C04035 screws and the 068843 washer. The washer goes on the screw closest to
TBR connector. Apply the number 2 of the C02293 decal to the escutcheon plate.
7. Remove the PCU Comm. cable that connects P3 of the RS485 Protection board to TBK on the existing Pump I/O
board. Install the C06608 PCU comm. cable from TBK on the existing Pump I/O board to TBK on the new Pump I/O
board and to P3 on the RS485 Protection board. If the unit has 2 protection boards, the cable connects to the upper
board.

NOTE: If a C06757 surge protector already exists (see pedestal left side view for location), skip Step 8 and proceed
with Step 9. Keep surge protector supplied in kit as a spare.
8. While facing the terminal block/bracket assembly, with TB2 on it, locate an unused captive nut in the sheet metal
(several inches below and to the right). Install the C06757 surge protector using a C04037 screw and 068842
lockwasher. Terminate the green/yellow wire from the surge protector to Ground of TB2 and the black wires from the
surge protector to Hot and Neutral on TB2.
9. For pump wiring to the Pump Control Unit, refer to the Islander II Installation Manual C35963. Once wiring is complete
and verified, re-connect the AC power to the Islander. Switch on AC power to the Islander and PCU power supply. After
wiring has been completed and tested, replace pedestal side covers.
