Installation instructions

Installation

1. Attach the 872 mounting bracket to a desired solid surface, in any orientation, using standard avail­able hardware such as machine screws. Avoid locating directly on high vibration equipment such
as air handling units.

2. Remove the standard 264/C264 back-plate/mounting bracket by removing the one Phillips head screw.
Caution: The circuit board of the 264/C264 is now exposed. DO NOT TOUCH - Electrostatic
Discharge (ESD) could damage the unit.

3. Mount the 264/C264 pressure transducer/transmitter onto the 872 bracket just as it was
mounted to the standard bracket with the same Phillips head screw.

4. Install conduit and wire per the 264/C264 operating instructions.

5. Snap the plastic cover into place over the bracket.

6. Be sure to ground cable shield wire to metal mounting bracket. Any of the screws that attach to the
mounting bracket can be used to secure the shield wire.

7. VERY IMPORTANT: (For 872-RFI only) in the Model 872-RFI there is a .156” DIA. hole on front of
cover and # 6-32 tapped hole in the bracket. Insert #6-32 screw included to provide an electrical
ground between base plate & cover.
