Rockwell Automation 1771-CFM Config. Flowmeter Installation Instructions - Manual (Page 7)

Configurable Flowmeter Module 7
Publication 1771ĆIN043B-EN-P - July 2002
Install the Module
When you insert or remove the
module while backplane power is
on, or you connect or disconnect
the wiring arm with field power
applied, an electrical arc can
occur. This could cause an
explosion in hazardous location
installations. Be sure power is
removed or the area is
nonhazardous before proceeding.
Remove power from the 1771 I/O
chassis backplane before you
install the CFM module. Failure
to remove power from the
backplane could cause:
•
injury
•
equipment damage due to
unexpected operation
•
degradation of performance
At power-up, the active and fault indicators
are on. An initial module self-check occurs.
If there is no fault, the fault indicator
turns off. See page 16 for information on
interpreting the status indicators.
The 1771–CFM module is a modular
component of the 1771 I/O system requiring a
properly installed system chassis. Refer to
publication 1771–IN075 for detailed
information on acceptable chassis, proper
installation and grounding requirements. Limit
the maximum adjacent slot power dissipation
to 11W maximum.
!
ATTENTION
!
WARNING
Place the module in the card guides on the top and bottom ofthe
chassis that guide the CFM module into position.
Important: Apply firm even pressure on the module to seat it into its
backplane connector.
