Example:
The priority drive direction in the event of a bus fault ("UP", "DOWN" or no movement)
can also be preset for all relays with the hand encoder depending upon the A-B bridge.
Normally this bridge is inserted and the priority direction is "UP" (channel setting "1"). If
"0" is set, the DRO 4 will - in the event of a bus fault - activate the drive direction "DOWN"
provided the bridge is in place.
If the A-B bridge is removed, the DRO 4 will not activate the motors when a bus fault oc-
curs.
9. Putting into Service
9.1. Connections
Only an authorized expert is allowed to carry out the installation. When installing, the
connection diagram has to be observed. All conductors that shall be connected have to
be free of voltage. Following table shows the connections:

a. On bus fault - please see chapter 8 "Coding".
Short circuits between Dupline signal conductors and the 24 V operating voltage or con-
nections to the grounding lead to malfunction and are not allowed. The correct polarity
of operating voltage and Dupline signal conductors has to be ensured.
In order to meet the requirements for protective low voltage, VDE 0100, Part 410, should
be observed and put into practice during installation.
When connecting please observe that the maximum torque of the terminals of 0.6 Nm
