Installation
Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the
document.
Connect the sensor to the module
Potential Electrocution Hazard. Always disconnect power to the instrument when making electrical
connections.
Electrocution Hazard. High voltage wiring for the controller is conducted behind the high voltage barrier in the
controller enclosure. The barrier must remain in place except when installing modules, or when a qualified
installation technician is wiring for power, relays or analog and network cards.
Potential Instrument Damage. Delicate internal electronic components can be damaged by static
electricity, resulting in degraded performance or eventual failure.
To install the module and connect the sensor, refer to the illustrated steps that follow and the
applicable wiring table:
• pH and ORP sensors with attached cables:
• pH and ORP sensors with removable cables:
• D5500 series dissolved oxygen sensor:
Note: Some combination sensors do not have wires for temperature measurement. If the metal braid of a
combination sensor is tinned, cut off the tinned area.
Note: When additional immunity is needed, connect the clear wire with the black band (pHD sensors only) to the
controller chassis.
Note: If the sensor cable is not long enough to reach the controller, an interconnect cable and junction box are
required to extend the distance.
