7.5 Electrical interface assignment
▶
For electric installation, proceed according to applicable regulations for electrical
engineering.
▶
You must ensure that the power supply is disconnected and also safeguarded
against being switched on unintentionally.
▶
Unintended activation should be prevented by means of a warning sign indicating
that work is carried out at the electrical system.
For operation of the hydraulic power unit, at least the following electrical
connections are required:
1. 12X1: Feed-in/voltage supply (fig. 13)
2. 15X1: Enable signal 24 VDC (fig. 14 and 16).
3. 21X1: Multi-Ethernet interface ("Premium" configuration only)
In "Basic" configuration, the filling level and temperature sensor as well as the filter
contamination sensors (fig. 15) must also be connected for respective evaluation via
the machine control system.
Make sure that the switch-off signals of the oil temperature, filling level and filter
contamination initiate deactivation of the hydraulic power unit "Basic"
configuration. For example, by means of deactivation of the 24 VDC enable or the
electric power supply.
The CytroPac is equipped with the Rexroth EFC 5610 frequency converter that
can be connected via Mini USB cable to an external PC.
The frequency converter can be accessed and configured via the ConverterWorks
or IndraWorksDS software.
The software is available for download on the Bosch Rexroth website. See
chapter 17.3 "Accessories".
