INSTALLATION
Mechanical Installation
The Model 340N2 transmitter can be surface mounted onto a panel, attached to DIN rails using adapter clips or wall mounted
using optional enclosures
Location
Although the device is encapsulated, all wiring connections are made to exposed terminals The unit should be protected
from weather and moisture in accordance with electrical codes and standard trade practices
In any mounting arrangement, the primary concerns are ease of wiring and attachment of the programming cable The unit
generates very little heat so no consideration need be given to cooling or ventilation
Surface Mount Installation
The Model 340N2 transmitter can be mounted to the surface of any panel using double-sided adhesive tape or by attaching
fasteners through the holes in the mounting flanges of the unit
Din Rail Mounting
Optional clips snap onto the mounting flanges allowing the transmitter to be attached to DIN 15, 32, 35 mm DIN rail systems
Wall Mounting
Optional metal and plastic enclosures are available for the Model 340N2 transmitter The enclosure is first attached to the wall
using fasteners through its mounting holes
After wiring, the transmitter may be attached to the enclosure with the terminal headers facing in using the slots in the
mounting flanges As an alternate mounting arrangement, the Model 340N2 transmitter can be fastened to the box cover
using double-sided adhesive tape

TEMPERATURE SENSOR INSTALLATION
The location of the temperature sensors with regard to the flow sensor is important to the accuracy of the energy calculation
Temperature sensor T1 must be located closest to the flow sensor.
A distance of 5 pipe diameters will give the greatest
accuracy
Always install the temperature sensor downstream of the flow sensor.
