•
Install the device to exclude any mechanical damage or friction during the application.
Pay particular attention to flow conditions and tank fittings.
•
Support extension tube of the device if a dynamic load is expected.
Intrinsic safety
•
The device is only suitable for connection to certified, intrinsically safe equipment with
explosion protection Ex ia.
•
The intrinsically safe input power circuit of the device is isolated from ground.
The dielectric strength is at least 500 V
rms
.
Potential equalization
•
Integrate the device into the local potential equalization.
•
