Chapter 3: Rewiring and Enclosure Installation

Rewiring

The MyDro features removable terminals. Your strategy may involve removing 

one wire at a time from the Legacy RTU and immediately terminating it onto the 

corresponding removable terminal. Nevertheless, it is a good idea to photograph 

the existing installation and label wires before decommissioning the Legacy RTU.

1. Turn AC power off to the Legacy RTU, remove the leads and either terminate 

them to the corresponding terminal or temporarily insulate them. Repeat for 

battery leads.

2. Unscrew the SMA connector from the antenna connector.
3. Remove the four screws holding the PCB down. These screws will be reused.
4. Refer to the appropriate section for reassembly information based on your 

enclosure.

5. Reterminate remaining conductors into their respective removable terminals. 

You may choose to power up the RTU and insert one bank of removable    

terminals at a time so that any wiring problems can be more easily identified. 

The removable terminals have been labeled to assist you with this step.
