Wi-Fi/GPS Unit
For the IntelliRupter fault interrupter R3 communication module, with the Wi-Fi/GPS
Unit comes congured to be a direct replacement for the Wi-Fi/GPS Unit in the R0
communication module. This is the default wiring for the R3 Communication Module.
To obtain remote access to the Wi-Fi/GPS User Interface the WAN must be routed
through the Wi-Fi/GPS Unit. Doing so will enable remote firmware updates and will be
required for some cybersecurity features provided in future releases of the Wi-Fi/GPS
firmware.
To configure the R3 Communication Module with the alternate wiring needed to route
WAN traffic through the Wi-Fi/GPS, follow these steps to convert the R3 Communication
Module from the default R0 Communication Module wiring to the alternate R3 Commu-
nication Module wiring:
STEP 1. Open the R3 Communication Module by unscrewing the thumb screw for the
battery access panel and removing the ve ⅜-inch hex bolts retaining the
communication device carriage.
STEP 2. Pull the communication device carriage out from the outer shell.
STEP 3. At the communication device, unplug the RJ45 cable that runs between the
communication device and the control module.
STEP 4. At the Wi-Fi/GPS Unit, plug the RJ45 cable from the control into Ethernet 1 on
the Wi-Fi/GPS Unit. See Figure 20 on page 22.
STEP 5. Locate the Ethernet patch cord provided with the R3 Communication Module
and plug one end into Ethernet 2 on the Wi-Fi/GPS Unit and the other into the
Ethernet port on the communication device.
STEP 6. Reassemble the communication module by inserting the communication
device carriage into the outer shell.
STEP 7. Insert and tighten the ve ⅜-inch hex bolts retaining the communication
device carriage. Then, close the R3 Communication Module by screwing in the
thumb screw for the battery access panel.
STEP 8. Use the R3 Communication Module Web user interface to reassign the existing
IntelliRupter Control Module IP address setpoint to the R3
communication module Ethernet 2 interface Static IP address setting. See
Figure 11 on page 14.
STEP 9. Use IntelliLink Setup Software to change the IntelliRupter Control Module
IP address setpoint to 192.168.1.2. See S&C Instruction Sheet 766-530 for
information about setting the IntelliRupter fault interrupter IP address.
This will be a private IP address. The R3 Communication Module performs
network-address translation to hide this private address.
This allows remote access to the Wi-Fi/GPS Unit user interface and will be
required for some cybersecurity features provided in future releases of the Wi-Fi/GPS
firmware.
NOTICE
Proper grounding with a wrist strap connected to ground is required when
touching any components within the communication module or contacts on the R3
Communication Module connector.
