RSU-503 Redundancy Switch Unit Introduction
Rev. 8 1–3
Although there are no external indicators or switches (due to the nature of the
weatherproof housing), there is an access panel that can be removed, allowing use of
internal switches and indicators (refer to Chapter 4 for more information).
Note: The internal indicators and switches are only used for factory testing and
troubleshooting.
The system, during setup and while running, is intended to be controlled remotely.
Refer to Figure 1-2 for an interconnection block diagram of the switch.
