Chapter 4 Installation
4.1 Overview
The information in Chapter 4 explains installation.
4.2 Safety Messages
Procedures and instructions in this chapter may require special
safety measures to ensure the safety of the personnel performing
the operation. Potential installation safety issues are indicated by a
safety alert symbol ( ). Refer to the following safety messages
before installing the 3100 pressure transmitter.
4.3 Warning
4.4 Commissioning on the Bench with Hand-Held Terminal
The 3100 Pressure Transmitter can be commissioned before and
after installation. Commissioning is easier if the transmitter is
configured on a bench with an HHT before installation.
4.5 General Considerations
The transmitter can be mounted near the process to minimize piping.
Keep in mind that easy access is required for personnel, field
calibration, and installation. Install the transmitter in an area with
minimal vibration, shock, and temperature fluctuations.
4.6 Electrical Considerations (Power Supply)
The transmitter housing is composed of two parts. One side is
electronics, and the other side is terminal block. The terminal block
side is the transmitter’s front side and is labeled “Field Terminal” on
the housing. The terminal block can be accessed by removing the
front cover. When wiring the power supply to the transmitter make
sure the positive and negative wires are connected correctly.
A HHT configurator can be connected directly across the (COMM)
pin terminal located just below the power supply (PWR) terminal
block connections.

Electrical shock can result in serious injury: Only qualified
personnel can wire the pressure transmitter. WARNING
Process leaks can cause death or serious injury: Install and
tighten before applying pressure. If you don’t, it can cause
process leaks.
WARNING
Explosion can result in death or serious injury: Do not remove
the transmitter covers in an explosion-proof environment when
the circuit is powered. Both transmitter covers must be fully engaged to meet the
explosion-proof requirements.
DANGER
Electrical shock can result in death or serious injury:
Avoid contact with the leads and terminals. DANGER
