Install The I/O Module - Allen-Bradley 1756-IF8I User Manual

Install the I/O Module

WARNING:
• This equipment shall be mounted in an ATEX-certified enclosure with a
minimum ingress protection rating of at least IP54 (as defined in IEC60529)
and used in an environment of not more than Pollution Degree 2 (as defined in
IEC 60664-1) when applied in Zone 2 environments. The enclosure must have a
tool-removable cover or door.
• This equipment shall be used within its specified ratings defined by
Rockwell Automation.
• Provision shall be made to prevent the rated voltage from being exceeded by
transient disturbances of more than 140% of the rated voltage when applied in
Zone 2 environments.
• This equipment must be used only with ATEX certified Rockwell
Automation backplanes.
• Secure any external connections that mate to this equipment by using screws,
sliding latches, threaded connectors, or other means provided with
this product.
• Do not disconnect equipment unless power has been removed or the area is
known to be nonhazardous.
You can install or remove a module while chassis power is applied. Removal and
Insertion Under Power (RIUP) provides the flexibility to maintain modules
without having to stop production.
WARNING: When you insert or remove the module while backplane 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.
Repeated electrical arcing causes excessive wear to contacts on both module and
its mating connector. Worn contacts may create electrical resistance that can affect
module operation.
ATTENTION: The module is designed to support Removal and Insertion Under
Power (RIUP). However, when you remove or insert an RTB with field-side
power applied, unintended machine motion or loss of process control can occur.
Exercise extreme caution when using this feature.
