3.3  Board connections 

This  instrument  is  an  electrical  apparatus:  it  must  therefore  be  installed  by 
trained  personnel.  Start-up,  maintenance  and  the  following  tests  must  be 
carried out by qualified personnel. 

3.3.1 

Power supply 

Use  a  power  supply  cable,  with  suitable  protection  to  the  environment  in  which 
they are installed, with a maximum diameter of 1,5 mm

2

. 

3.3.2 

Load cell 

The load cell provides a  low-level signal (a few millivolts); it  is therefore essential 
for  a  correct  application,  use  good  quality  shielded  cables.  For  single-cell 
applications  with  distance  equal  to  or  less  than  8  meters  is  enough  the  4-wire 
connection. 
 

The  connection  to  the  load  cells  must  be  done  with  high  quality  shielded 
cable.  The  cable  CAB-TS6  Logic  model  is  recommended  for  all  industrial 
applications including areas with risk of explosion. 
 

In  applications  with  more  load  cells  (platforms,  tanks,  silos,  etc.),  It  is 
recommended the use of junction boxes that minimize differences in impedance or 
compensation on the signal branches. The junction boxes JBOX series have been 
designed for this purpose and properly solve the problem. 
 
The maximum cable length between the junction box and the instrument, depends 
on the specific situation of electrical noise in the plant, which potentially can induce 
noise on the signal cable. In normal situations cable lengths up to 300 meters can 
be used without problems. 
The shielded cable must be positioned preferably in metal conduit grounded and in 
any case away from any other power supply cable or power cable. 
Verify,  before  and  during  the  installation  of  the  cable  cells,  which  do  not  occur 
entry  of  moisture  in  the  same  cable,  causing  loss  of  insulation  and  consequent 
malfunction. 

3.3.3 

Ground connections 

The  ground  connection  is  very  important  for  compliance  with  electromagnetic 
compatibility and therefore for the reliability of the apparatus. 
Respect  and  carefully  check  ground  connections  indicated  on  the  attached 
diagrams in order to prevent possible malfunctions. Connect the shielded cable to 
the  GND  terminal  of  the  terminal  blocks;  the  other  end  of  the  screen  normally  is 
isolated. 
 

In  presence  of  strong  interferences  (inverter  etc.),  connect  to  ground  both 
heads of the screen. In this case it is important to have low values of ground 
resistance.
