I/O Block Base Installation
Purpose/Scope
This procedure gives the steps required to install a termination
base for an I/O block. The procedure is the same whether
installing a nonredundant or redundant base. A redundant
base, however, requires a redundant mounting column.
Parts
None.
Tools
•
Phillips screwdriver.
Procedure
□
1. Verify the block location. I/O blocks can be located any-
where within an enclosure in any available, empty mounting
position.
□
2. Position the base on the mounting column. Insert the tabs
at the back, left side of the base into the slots in the column as
shown in Figure
PR2-1 . Tilt the base slightly to properly insert
the tabs. The base is properly positioned when the posts on
the back of the base line up with the alignment holes in the
column. The mounting column connectors should protrude
through the base.
□
3. Tighten the two captive screws to attach the base to the
column. A redundant base has four captive screws.
□
4. Verify the back of the base is flush with the mounting
column.
