RDR2S Module Components
The RDR2S module consists of two electrical printed circuit boards (PCBs) in a
plastic enclosure. The bottom PCB is a wiring base and the top PCB is an electronics
board.
The electrical printed circuit boards are interconnected via a 2x25 pin header. The
bottom board (wiring base) is mounted onto
the bottom enclosure with four No 3
screws. The top board (electronics board) is mounted onto the top enclosure with
four No 3 screws. The separation between the two boards is approximately 1 inch.
The RDR2S module is shipped fully assembled.

CAUTION
If DC power has already been connected to the unit, disconnect the DC
power before separating the electronics board from the wiring base.
