I/O Module Installation
Purpose/Scope
This procedure gives the steps required to install an I/O mod-
ule. The installation procedure is the same for all I/O modules.
Also, the procedure is the same whether installing modules on
redundant or nonredundant bases.
NOTE: Always follow the instructions given in
Special Handling
in Section 5
when handling an I/O module.
Parts
None.
To o l s
• Flat-blade or Phillips screwdriver.
Safety Considerations
Procedure
□
1. Verify the block location. I/O modules are keyed to compat-
ible bases to prevent a mismatch.
□
2. Grasp the retractable handle when inserting the I/O mod-
ule. Insure the handle is extended completely so that the fas-
tening screw does not stick out from the back of the module
(Fig. PR3-1).
□
3. Position the I/O module on the base. The I/O module is
properly positioned when the posts protruding from the base
line up with the alignment holes on the back of the I/O
module.
NOTE: Do not use the fastening screw to align the I/O module.
□
4. Gently push the module in until the front of the base and
the front of the I/O module are flush. This should not require
1 min.
WARNING
1. An I/O module should not be inserted or removed with power
applied when located in a class I, division 2 hazardous location
unless the area is known to b e nonhazardous.
