OVERVIEW
This section contains a flowchart (Figure 4-1 on Page 4-2), installation procedures,
and a wiring diagram (Figure 4-8 on Page 4-10), to guide you to a successful Model
PX2088 installation. Shielded cable should be used for best results in
electrically noisy environments.
Safety Messages
Instructions and procedures in this section may require special precautions to
ensure the safety of the personnel performing the operations. Please read all
warnings before proceding.
Explosions could result in death or serious injury:
Do not remove the transmitter cover in explosive atmospheres
when the circuit is alive.
Before connecting a HART-based communicator in an explosive atmosphere, make
sure the instruments in the loop are installed in accordance with intrinsically safe or
non-incendive field wiring practices.
Verify that the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
Both transmitter covers must be fully engaged to meet explosion-proof requirements.To
avoid output shifts in critical applications, do not plug the low side with a solid plug.
To avoid process leaks, install and tighten all four flange bolts before applying
pressure, or process leakage may result. When properly installed, the flange bolts will
protrude through the top of the module housing. Attempting to remove the flange bolts
while the transmitter is in service may cause process fluid leaks.
Failure to follow these installation guidelines could result in death or serious injury:
Make sure only qualified personnel perform the installation.
