The RTG 3900 version without Integrated Junction Box is delivered with

 

a 2 m long cable. If the distance between the transmitter and connected

 

devices is longer than 2 meters, a junction box must be used to connect

 

an extension cable. The extension cable must not be longer than 50 m.

 

An external junction box can either be customer supplied or supplied by

 

Emerson Process Management/Rosemount Tank Gauging as an option.

 

 

Note!

For safety reasons unused wires must be properly insulated and

 

terminated.

 

 

 

 

A flexible protective hose for the wires is delivered with the transmitter. If

 

a DAU is used, it is very important that a continuous metal shield covers

 

the wires between the Transmitter Head and the DAU to avoid

 

electromagnetic interference between cables. If an extension cable is

 

used, both the cable and the junction box must provide good shielding.

 

 

Note!

Select external fuse rating with respect to area temperature classification

 

(T1-T6) and maximum expected ambient temperature to prevent

 

overheating of the internal wiring in the JBI junction box (0.5 mm²).

 

Example: Max. allowed (fault) current in a T4 installation with 70°C

 

ambient is 7.5 A acc. to the lead seal component certificate PTB 97

 

ATEX 1047 U.
