3. Wiring
Chlorine Digital (S 3 L) Wiring
• Remove approximately 10 mm (0.4 in.) of insulation and tin each conductor before inserting into terminals.
• Refer to the wiring diagram above to connect the 2650 cable to the terminals on the
8630 Chlorine Transmitter.
• Maximum cable length is 30 m (100 ft).
• Cable should have noise immunity for the sensor signal of up to 30 m (100 ft).
• Cable capacitance must be less than 30 pF/foot.
