INSTALLATION OF DYNAMIC BRAKING UNIT
25
Connections between multiple DB Units (‘Master’ and ‘Slaves’)
To connect the dynamic braking unit configured as ‘Master’ with
one of the dynamic braking units configured as ‘Slave’:
o
Connect terminal ‘OUT+’ of DB Unit ‘Master’ to terminal
‘IN+’ of DB Unit ‘Slave’.
o
Connect terminal ‘OUT-‘ of DB Unit ‘Master’ to terminal ‘IN-‘
of DB Unit ‘Slave’.
See figure 4.8.
To connect two dynamic braking units configured as ‘Slaves’
between them:
o
Connect terminal ‘OUT+’ of the first DB Unit ‘Slave’ to
terminal ‘IN+’ of the second DB Unit configured as ‘Slave’.
o
Connect terminal ‘OUT-‘ of the first DB Unit ‘Slave’ to
terminal ‘IN-‘ of the second DB Unit configured as ‘Slave’.
See figure 4.8.
The following figure shows the correct wiring between the drive and
several dynamic braking units connected in parallel with their
corresponding braking resistors each one. One DB Unit will act as
‘Master’ and the others will act as ‘Slaves’.
