can also be preset with the hand encoder; the standard setting is „UP".

9. Putting into Service

Installation may only be carried out by an authorized technician. Observe the connection
diagram when installing. All leads to be connected must be dead.
The phase input serves to supply the unit as well as the actuating output.
In order to avoid malfunctions, the length of the line between push-button and the
DRO 1U should not exceed 3 m under normal environmental conditions and 1 m in in-
dustrial environments.
In order to make sure that the Dupline signal conductors have identical length,
please always lay both leads (Dupline + and -) towards the push buttons or
contacts!
The Dupline signal conductor (Dupline -) should be used as common potential, with the
connection being made directly at the terminal. The following table illustrates the connec-
tion configuration:

Connections between the Dupline signal and earth potential will cause malfunctions and
are not permissible. Attention should be paid to the correct polarity of the Dupline signal.
Because of the integrated power pack, the DRO 1U will warm up slightly after a short run-
ning time. This is, however, no cause for concern.
In order to meet the requirements for protective low voltage, VDE0100, Part 410, should
be observed and put into practice during installation. For safety reasons mains cables
may not be routed through the same installation box.
