INSTALLATION
Inspection Inspect the package for damage. If damaged, notify the
appropriate carrier immediately. If undamaged, open the
package and inspect the device for obvious damage.
Return damaged products.
Requirements • Tools (not provided)
- Digital Volt-ohm Meter (DVM)
- Appropriate screwdriver for mounting screws
- Appropriate drill and drill bit for mounting screws
• Appropriate accessories
• Two #8 self-tapping mounting screws (not provided)
• Training: Installer must be a qualified, experienced technician
Warning:
• Do not use on oxygen service, in an explosive/hazardous
environment, or with flammable/combustible media.
• Disconnect power supply before installation to prevent
electrical shock and equipment damage.
• Make all connections in accordance with the job wiring diagram
and in accordance with national and local electrical codes. Use
copper conductors only.
Caution:
• Use electrostatic discharge precautions (e.g., use of wrist
straps) during installation and wiring to prevent equipment
damage.
• Avoid locations where severe shock or vibration, excessive
moisture or corrosive fumes are present. NEMA Type 4
housings are intended for outdoor use primarily to provide
a degree of protection against wind-blown dust, rain, and
hose-directed water.
• Do not exceed ratings of the device.
Mounting The PR-264 must be mounted on a vertical surface with the 1/8"
NPT connection pointed downward. Refer to Figure 7 for
mounting dimensions.
1. Remove the transducer cover using a Phillips head
screwdriver.
2. Select the mounting location.
3. Mount transducer on a vertical surface with two #8 self-tapping
screws (not provided).
4. Pull wires through bottom of enclosure and make necessary
connections.
5. Replace the unit cover and make pneumatic connections.
Wiring
Use maximum 12 AWG wire for wiring terminals. Use copper or
stainless steel tubing for the connection to the transducer. Refer
to Figures 1, 2, 3, & 4 for wiring information and Figures 5 & 6 for
switch designations.
