Installation
WARNING
Always wear protective clothing, gloves, and eyewear when performing any installation operations to avoid personal
injury.
To avoid personal injury or property damage caused by the sudden release of process fluid, be certain the service
conditions do not exceed the sensor pressure limits. Use pressurelimiting or pressurerelieving devices to prevent service
conditions from exceeding these limits.
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
If installing this into an existing application, also refer to the WARNING at the beginning of the Maintenance section of this
instruction manual.
CAUTION
If the L2e electric level controller is installed on a vessel that is to be shipped to a different location (e.g. skid mounted
units), remove the displacer and displacer rod extensions before shipment. Failure to do so could result in damage to the
instrument and or the displacer rod due to vibration and impact loading during shipment. After the vessel is installed at its
final location, reassemble the displacer and displacer rod extension.
Note
Use with easyDrive electric actuator after first being used in other high power application is not recommended.
