Control terminal block and serial interface

The common rectifier must be isolated before connecting the control leads to the CUR.
You can control the common rectifier over the following interfaces:
♦ Control terminal block on the CUR electronic module
♦ RS 485 serial interface on the CUR electronic module
♦ Operator control panel OP1S (see Chapter 9 Options)
♦ RS485 and RS232 serial interface on the PMU X300
The CUR incorporates ESD-endangered components that may be destroyed if improperly
handled.
See also under the measures recommended to protect ESD-endangered components in
the introductory chapter entitled "General".

Connectors for the control terminal block

Conductors with cross-sectional areas of 0.14 to 1.5 mm
stranded with core end ferrules, can be connected to the connectors (Recommended: 0.5 mm
3.3.2

Connecting the control leads

In general, control wires connected directly to the converter should be shielded to ensure that the highest
level of noise immunity is achieved. The shielding must be grounded at both ends. On the unit's housing,
the shield is connected with shield clamps. Handling of these clamps is shown in Figure 3.4.
To prevent the injection of disturbance, control wires connected directly to the unit must be laid separately
from power cables. Minimum distance 20 cm.
If they intersect, control and power cables must be run at an angle of 90° to each other.
If converters are installed in systems by authorized workshops, noise immunity can also be provided by
other appropriate wiring practices.
