Wiring Installation in 4838 Reactor Controller
Warning: Take care not to apply too much torque when tightening down on wires.
This can cause them to weaken and break.
1. Take the black and white cable, with both ends stripped, from the kit and attach one end to
the 2082E meter. Connect the white wire #6 to pin 11 and black wire #7 to pin 12.
Attach the other stripped end of white wire #6 to the 2083E Primary Temperature Meter in
position 10 and the black wire #7 to the 2083E Meter position 9.
2. Find the free black wire #4 from the kit and attach one end to pin 1 on the 2082E meter.
The other end attaches to terminal block position #4.
Note: The terminal block position can be opened up using a small flat head screw driver to
release the tension from the spring inside the block so you can press the wire against the
spring.

3. Find the free white wire #3 from the kit and attach one end to pin 2 on the 2082E meter.
The other end attaches to terminal block position #3.
4. Find the free orange wire #1 from the kit and attach one end to pin 8 on the 2082E
meter. The other end attaches to the 2083E Meter position 14.
5. Find the free blue wire #2 from the kit and attach one end to pin 7 on the 2082E
meter. The other end attaches to terminal block
position #3.
6.
Locate the thermocouple jack on the back of the 4848
controller labeled "TEMPERATURE INPUT". Slip one
1541E bead on the red and the white wire. Attach the
1398E2 internal thermocouple wire to the jack by
wrapping the wires around the posts and tightening them.
Attach the other end to the 2082E meter; the red wire to
Pin 6, and the white wire to Pin 4.
