4.1 Overview
This section describes how to install QTA DIN rail mount transmitters. The following general steps are
required:
•
Determine the location of the transmitter and other flowsensor components (see Section 4.2)
•
Mount the transmitter (see Section 4.3)
•
Ground the transmitter (see Section 4.4)
•
Supply power to the flowsensor (see Section 4.5)
4.2 Determining an Appropriate Location
See Figure 4.2.5 for the DIN rail mount installation architecture.
To determine an appropriate location for the transmitter, you must consider the temperature
requirements of the transmitter, hazardous area issues, location of power source, cable lengths, and
accessibility for maintenance.
Figure 4-1 Installation Architecture
4.2.1 Temperature Requirements
Install the transmitter in an environment where ambient temperature is between –40 and +131 °F
(–40 and +55 °C).
Different ambient temperature requirements may apply, depending on your installation. Refer to the
approvals documentation included on the CD shipped with the transmitter.
4.2.2 Hazardous Area Classifications
The QTA DIN rail mount transmitter is designed for installation in a safe area. It can be connected to
a sensor located in a hazardous area.
For more information about hazardous area classifications, see Appendix A.
4.2.3 Power Source
The transmitter must be connected to a DC voltage source. Do not use an AC power supply.
