Grounding
The SmartRadar housing must be properly grounded to the ground reference
(generally the tank), according to local regulations. This is a safety grounding
requirement.
4.11.2
Introduction
Location
The terminal compartment is located at the rear, inside of the device (refer to figure
4.7). If there is a SmartConn present, you use the terminals of the SmartConn (refer
to figure 4.6). These terminals are numbered identical to the terminal compartment in
the device.
Warning!
When measuring the ground resistance, use a suitable instrument
which is approved for use in hazardous areas.
Caution!
Safety depends on proper grounding. Check the resistance of the
ground connection directly after installation. The measured ground
resistance must be below the maximum prescribed by local and/or
national grounding requirements.
Caution!
The intrinsically safe options have been certified for use in hazardous
areas. Make sure that the certificate of approval is available on site
and act in accordance with the instructions as given in the certificate.
Caution!
Intrinsically safe wiring must be separated from all other wiring. The
cable lay-out must be in accordance with local and/or national
regulations.
NOTE
Connect the armouring of the cable externally in the cable gland at
both ends of the cable.
