Installing the Module
CAUTION! Electrostatic discharge (ESD).
The modules' signal inputs are sensitive to electrostatic discharge.
Take measures to protect against ESD before inserting the module and wiring
the inputs.
Note: Strip the insulation from the wires using a suitable tool to prevent dam-
age.
