WARNING: If you insert or remove the module while power is on, an electrical arc can occur. This could
cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
WARNING: The local programming terminal port is intended for temporary use only and must not be
connected or disconnected unless the area is assured to be nonhazardous.
WARNING: When used in a Class I, Division 2, hazardous location, this equipment must be mounted in a
suitable enclosure with proper wiring method that complies with the governing electrical codes.
WARNING: If you connect or disconnect wiring while the field-side power is on, an electrical arc can
occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or
the area is nonhazardous before proceeding.
WARNING: The USB port is intended for temporary local programming purposes only and not intended for
permanent connection. If you connect or disconnect the USB cable with power applied to this module or
any device on the USB network, an electrical arc can occur. This could cause an explosion in hazardous
location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
The USB port is a nonincendive field wiring connection for Class I, Division2 Groups A, B, C and D.
WARNING: Exposure to some chemicals may degrade the sealing properties of materials used in the
Relays. It is recommended that the User periodically inspect these devices for any degradation of
properties and replace the module if degradation is found.
WARNING: To comply with the CE Low Voltage Directive (LVD), this equipment must be powered from a
source compliant with the following:
Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV).
WARNING: To comply with UL restrictions, this equipment must be powered from a source compliant with
the following:
Class 2 or Limited Voltage/Current.
WARNING: Do not wire more than 2 conductors on any single terminal.
WARNING: Be careful when stripping wires. Wire fragments that fall into the controller could cause
damage. Once wiring is complete, make sure the controller is free of all metal fragments.
ATTENTION: Do not remove the protective debris strips until after the controller and all other equipment
in the panel near the module are mounted and wired. Remove strips before operating the controller. Failure
to remove strips before operating can cause overheating.
ATTENTION: Electrostatic discharge can damage semiconductor devices inside the module. Do not touch
the connector pins or other sensitive areas.
ATTENTION: This product is intended to be mounted to a well-grounded mounting surface such as a metal
panel. Additional grounding connections from the power supply'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.
ATTENTION: The USB cable is not to exceed 3.0 m (9.84 ft).
