● Terminals accept 16 to 28 AWG wire.
● Sensor cable length can be extended to 30 m (100 ft) (except 2819
and 2839, limited to 4.6 m (15 ft).
● Strip 10 to 12 mm (0.4 to 0.5 in.) of insulation from wire tips
and tin bare ends to eliminate fraying.
● Insert wire tip or ferrule completely into the terminal and
secure with the screw.
● Do not allow any AC leads that may be connected to the
internal relays to come in contact with low voltage wiring.

If the 9900 Base Unit will be mounted in a panel, plug-in modules may be
installed either before or after the base unit is mounted. If the 9900 Base
Unit will be mounted using the accessory wall mount bracket, install plug-in
modules fi rst.
The Conductivity/Resistivity module plugs in and attaches with a screw.
1. It may be helpful to use a standard screwdriver to gently pry
removable terminals away from the receptacle on the plug-in modules.
Reverse this step to reinstall the panel after the plug-in modules are
installed.
2. Remove terminals from the receptacle of each plug-in module prior to
installation.
To interface a stand-alone conductivity sensor (2819-2823 or 2839-2842) to the 9900, the 3-9900.394 Direct
Conductivity Module must be used.
CAUTION:
Exercise care when
installing module.
Do not bend connecting pins.
Align pins and connectors then push
module fi rmly into place, then attach with
screw.
Avoid Electrostatic Discharge (ESD):
● Minimize handling of module to
reduce the possibility of damage
due to ESD.
● Handle module by the edges. Never
touch any exposed circuitry
or contacts.
● Wear an anti-static wristband or
stand on an anti-static mat, or
keep one hand touching a properly
grounded pipe or other properly
grounded piece of metal when
handling module.
