Grounding the Module
This product is intended to be mounted to a well-grounded mounting surface such
as a metal panel. Additional grounding connections from the module's mounting
tabs or DIN rail (if used), are not required unless the mounting surface cannot be
grounded. Refer to Industrial Automation Wiring and Grounding Guidelines,
Allen-Bradley publication 1770-4.1, for additional information.

Sinking/Sourcing Inputs - Sourcing/sinking describes the current flow between the I/O
module and the field device. Sourcing I/O circuits supply (source) current to sinking field
devices. Sinking I/O circuits are driven by a current sourcing field device. Field devices
connected to the negative side (DC Common) of the field power supply are sinking field
devices. Field devices connected to the positive side (+V) of the field supply are sourcing
field devices. Europe: DC sinking input and sourcing output module circuits are the
commonly used options.

Miswiring of the module to an AC power source will damage the
module.
Be careful when stripping wires. Wire fragments that fall into a
module could cause damage at power up. Once wiring is
complete, ensure the module is free of all metal fragments.
