You can control the rectifier/regenerating unit over the following interfaces:
♦ Control terminal block on the CUR electronic module
♦ RS 485 serial interface on the CUR electronic module
♦ Operator 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.

Connecting the control leads

When installed, control leads must be shielded and isolated from the power cables, laying them at a minimum
spacing of 20 cm. The shield must be connected at both ends. On the unit's housing, the shield is
connected with shield clamps. Handling of these clamps is shown in Figure 3.6.
If they intersect, control and power cables must be run at an angle of 90° to each other.
