●
Minimize handling of the plug-in modules to reduce the
possibility of damage due to ESD.
●
Handle modules 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
piece of properly grounded metal when handling modules.
CAUTION
Avoid Electrostatic Discharge (ESD).
CAUTION
Exercise care when installing modules.
Do not bend connecting pins.
CAUTION
LOOP as well as DC power MUST be removed
BEFORE installing or removing ANY Module.
If the 9900 Base Unit will be mounted in a panel, the plug-
inmodules may be installed either before or after the base unit
is mounted. If the 9900 Base Unit will be mounted using the
wall mount accessory kit (3-9900.392), install plug-in modules
fi
rst. If installing both the Conductivity/Resistivity (Cond/Res)
and the H COMM Modules, install the H COMM Module
fi
rst,
then the Cond/Res Module on top of it.
To install modules:
Remove power from the 9900. Carefully align pins and
connectors (do not bend connecting pins) and push module
fi
rmly into place, then attach with screw(s) (except H COMM
Module).
