1.3.3 V.24 (RS-232) Interface for External Management

The 6-pos. Mini-DIN female connector provides a serial interface to connect a local

management station. Use the "PRG CAB MINI DIN" programming cable

(Order No. 2760611). It can be used to connect a VT100 terminal or a PC with

corresponding terminal emulation to the management interface (for an appropriate cable,

please refer to "Ordering Data" on page 6-2). Set the following transmission parameters:

1.3.4 Grounding

All Factory Line devices must be grounded so that any possible interference is shielded

from the data telegram and discharged to ground potential.

A wire of at least 2.5 mm

must be used for grounding. When mounting on a DIN rail, the

DIN rail must be connected with protective earth ground using grounding terminal blocks.

The module is connected to protective earth ground via a metal clip on the rear of the

housing.

Grounding protects people and machines against hazardous voltages. To avoid these

dangers, correct installation, taking the local conditions into account, is vital.

Option: In an environment particularly prone to EMI, noise immunity can be increased

by an additional low-impedance connection to functional earth ground via terminal 7

("Assignment of the COMBICON Connector" on page 1-6).
