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.
• 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.
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 cover and make pneumatic connections.
Use maximum 12 AWG wire for wiring terminals. Refer to Figures
1, 2, 3, & 4 for wiring information and Figures 5 & 6 for switch
designations.
