What is the first step to take before disconnecting the eRCT from the ATG for remote operation?

The first step to take before disconnecting the eRCT from the ATG for remote operation involves ensuring that the RCT 28 VDC switch is turned off. This is crucial because the 28 VDC power supply is essential for the operation of the Remote Control Terminal (RCT). Turning off this switch ensures that power is safely cut off from the RCT, thereby preventing any potential electrical hazards or damage to the system. Disconnecting power before performing maintenance actions or disconnections is a standard safety protocol, promoting safe operations and minimizing the risk of accidental short circuits or operational issues once the eRCT is reconnected in the future.

While stopping all signals, powering down the radar system, or unplugging the power supply might seem relevant actions, they are not the immediate first step necessary for a safe disconnect process. The priority is to manage the power to the RCT first, ensuring that the system is in a safe state before proceeding with any disconnection.
