UM353-1 Installation
March 2003
8-5
Installation:
1. Using a straight blade screwdriver with a 1/8" blade width, turn each
unused terminal screw clockwise until it is just tight - do not over
tighten.
2. Read the letters/numbers on the connector to be inserted and refer to
the adjacent figure for the connector location. Each connector is
keyed for the appropriate plug-in location.
3. Visually check that all 12 pins in the Connector Socket are straight.
If a pin is only slightly bent, very gentle straightening can be tried.
Excessive straightening may cause the pin to break requiring
replacement of the Connector Socket.
4. Align the connector with the pins in the Connector Socket and push
the connector straight in. See the adjacent figure.
5. Two pairs of rectangular tabs extend from the cover. Install the cover
by fitting one pair of tabs extending from one side of the cover into
two of the rectangular slots in a pair of terminals. Now, compress the
U-shaped extrusion slightly and fit the other pair of cover tabs into
the slots in the remaining pair of terminals.
6. The cover can be secured with two screws. Holes in the cover align
with holes in the connector socket assembly. Use 3-48 x ¼ long or
M2.5 x 6 long screws to secure the cover.
8.3.2 Panel and Rack Mounting Guidelines
The panel face should provide a flat and rigid mounting surface. Reinforce the back of the panel if there is a
possibility that the panel face will bow. Raceways, conduit, and wiring should not interfere with the removal or
accessibility of the instruments, control devices, alarms, and related equipment.
