Field Wiring Connections
Grounding the Module
In solid-state control systems, grounding and wire routing helps limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from the ground screw of the
controller to the ground bus prior to connecting any devices. Use AWG #14 wire. For
AC-powered controllers, this connection must be made for safety purposes.
You must also provide an acceptable grounding path for each device in your application. For
more information on proper grounding guidelines, refer to the Industrial Automation Wiring
and Grounding Guidelines, publication
1770-4.1 .
Output Type Selection
The output type selection, current or voltage, is made by wiring the appropriate terminals, Iout
or Vout, and by the input type/range selection bits in the Configuration Data File (see page 16).
WARNING EXPLOSION HAZARD
• In Class I, Division 2 applications, the bus connector must be fully seated and
the bus connector cover must be snapped in place.
• In Class I, Division 2 applications, all modules must be mounted in direct
contact with each other as shown on page 10. If DIN rail mounting is used, an
end anchor must be installed ahead of the controller and after the last
1762 I/O module.
ATTENTION
To comply with the CE Low Voltage Directive (LVD), all connected I/O must be
powered from a source compliant with the Safety Extra Low Voltage (SELV) or
Protected Extra Low Voltage (PELV).
