Radar Tank Gauge

 

 

4.3Equipotential bonding

Connect the Equipotential bonding to the external ground terminal of the transmitter.

Caution!

In Ex applications, the instrument must only be grounded on the sensor side. Further safety instructions are given in the separate documentation for applications in explosion hazardous areas.

4.4Degree of protection

housing: IP 65, NEMA 4X (open housing: IP20, NEMA 1)

antenna: IP 68 (NEMA 6P)

4.5Overvoltage protector

The level transmitter 7500 RTG is equipped with an internal overvoltage protector (600 Vrms electrode). Connect the metallic housing of the 7500 RTG to the tank wall directly with an electrically conductive lead to ensure reliable potential matching.

Installation with additional overvoltage protector HAW 262 Z (see XA 081F-A "Safety instructions for electrical apparatus certified for use in explosion-hazardous areas").

–Connect the external overvoltage protector and the 7500 RTG transmitter to the local potential matching system.

–Potentials shall be equalised both inside and outside the explosion hazardous area. –The cable connecting the overvoltage protector and the 7500 RTG transmitter shall

not exceed 1 m in length;

–The cable shall be protected e.g. routed in an armoured hose.

4.6Post-connection check

After wiring the measuring instrument, perform the following checks:

Is the terminal allocation correct (see page 25)?

Is the cable gland tight?

Is the housing cover screwed tight?

If auxiliary power is available:

Is the instrument ready for operation and does the liquid crystal display show any value?
