Figure 13: Wiring diagram for VDOT-UB4 and VDOT-UB4-6

 

 

SLC Line impedance is 50Ω at maximum and the maximum length is 2km. 
Refer to the manual of control panel series

 

to determine correct maximum loop load and maximum loop resistance 

for devices connected to each loop. 

 Use  cable  AWG12-20  for  wiring.  Do  not  connect  different  gauge  cables  at  one 
terminal in order to prevent loosening. 

  !   CAUTION  

 

Do  not  connect  cables  in  reverse  polarity.  Failure  to  connect  the  polarity  correctly 
could result in damage to other equipment.

  !   CAUTION

For system monitoring 

 For terminals 1 and 6 do not use looped wire under 

terminals. Break wire run to provide monitoring of connections. 

  !   CAUTION
