Proceed to Step 5 following 5500 DO sensor wiring directions page 52 to complete
sensor wiring.
4. On 5500D instruments there are two terminal strips at location H. Wire
system DO-1 and system DO-2 sensors to the upper terminal strip. Wire
system DO-3 and system DO-4 sensors to the lower terminal strip - see
figures 3.19a and 3.19b. The upper and lower DO sensor terminal strips are
inverted. Be sure ODO sensor wires follow the wire coding below.

• YSI 6060250 ODO DO sensor wires are red, green, white and black.
-Terminate red wire to 1R (“1”=DO1 “R”=red) and/or 2R, 3R, 4R.
-Terminate green wire to 1G (“1”=DO1 “G”=green) and/or 2G, 3G,
4G.
-Terminate white wire to 1W (“1”=DO1 “W”=white) and/or 2W,
3W, 4W.

-Terminate black wire to 1B (“1”=DO1 “B”=black) and/or 2B,
3B, 4B.
-Terminate bare ground/drain wire to E or F on metal plate.
Notes ground/drain wire termination:
- Install a ring (eyelet) or spade (fork) terminal onto the ground bare wire before
terminating ground wire to E or F.
- Multiple ODO ground/drain wires can be terminated to the same ground
location on the metal plate.
- Return screw at E or F over terminal connection of ground wire.
