Low Voltage (4-wire RS485) Surge Suppression PCB
Indoor Controller/Auxiliary Power Center(s)/TeleLink
Use the Low Voltage Surge Suppression PCB to protect the PCBs in any devices connected to the 4-wire
cable in the RS485 system. Inside the indoor controller, there is a specific area where the Surge Suppression
PCB can be mounted. To properly install the PCB and make sure that it does not interfere with other
components, use the template provided. Wire the PCB according to Figure 3.

Low Voltage (4-wire RS485) Surge Suppression PCB Wiring Diagram
Accessory PCB's
Each accessory added to the RS485 system will require its own Surge Suppression PCB (P/N 6585)
unless the accessory is wired "in series" and "downstream" of another accessory that already has a Surge
Suppression PCB installed. Figure 4 illustrates a typical RS485 system. Notice that the 3 controllers are
wired "in series" and are all protected by a Surge Suppression PCB installed in the first controller. The
TeleLink J-box requires its own Surge Suppression PCB because it is wired directly to the Power Center ("in
Parallel" to the controllers).
NOTE All wiring that exits the house, including wiring inside a screened porch, is susceptible to pick up and transfer
power surges to the controller(s) or the Power Center. Buried cables (in or out of conduit) from spa side
switches are also susceptible to transfer power surges. Ensure all low voltage wiring that runs outside the
house or Power Center is connected to a surge suppression board before it connects to other PCBs.
Proper bonding and grounding is necessary for surge suppression to protect the AquaLink RS system.
