05 INSTALLATION
Connection of the separate protective earth conductor and the power supply cable
The Xcontrol-E is to be operated stationary, and it is not allowed to connect it via plug socket, but directly.
DANGER: High leakage current
High leakage currents may occur. The Xcontrol-E must is to be operated stationary. It is not
allowed to connect it via power supply plug, but directly. The separate protective earth
conductor must be attached in any case. Otherwise, there is a risk that the high leakage
currents will flow through people and, in the worst case, can lead to death.
The separate protective earth conductor must be installed in such a way that there is permanent electrical
patency between the protective earth conductor and other equipment. In addition, sufficient mechanical
protection and strength of the protective conductor must be ensured. The protective earth conductor must be
connected as follows:
Connecting motor connection cable and sensor connection cable
The connection of the motor supply cable and the sensor connection cable to the spindle can be found in the
operating manual of X22.
Control line customer
The control cable, via all signals run from the machine control to the Xcontrol-E, must be connected to the terminal
block by the customer. For this purpose, the terminal block positions X1:17 and X1:18 as well as X1:23 and X1:43
and X1:55 are provided. Depending on the spindle configuration, not all terminals are necessary, but they are
already installed in case that the spindle should be upgraded in the future.
The control cable must have a cable cross-section in the range of 0.08 to 1.5 mm². It is recommended that the
wires are fitted with ferrules to ensure optimum contact. The terminals are to be operated as explained in the
following picture, e.g. with a screwdriver. Afterwards the wire can be inserted into the terminal and the
screwdriver can be removed again. (Check if the wire is firmly seated).
