Connecting cables to the system periphery
To obtain a better overview when connecting cables, only use as many
leads as necessary.
To connect cables to the system periphery, proceed as follows:
ü Use only the specified cables for wiring. Note the cable recommendation
[► 38].
► Connect the lines to be wired to the device to the system periphery as
shown in the connection diagrams supplied.
Supplying the voltage regulator using auxiliary voltage
The device is normally supplied by the voltage transformer. If the voltage
transformer does not provide the supply voltage and power (see "Technical
Data") needed for operation, the device must be supplied via a 88...265V
AC/DC, 50...60Hz auxiliary supply .
Proceed as follows to supply the device with auxiliary voltage:
1. NOTICE! Voltage transformer damage Connecting an auxiliary voltage
when bridges are present between the X2:1/3 and X2:2/4 terminals can
result in voltage transformer damage. Remove the bridges between the
terminals X2:1/3 and X2:2/4.
2. Connect the voltage transformer to terminals X2:1 and X2:2.
3. Connect the auxiliary voltage using the following terminals: X2:3 and
X2:4.
