NOTICE!
Risk of damaging the PLC modules!
The PLC modules must not be removed while the plant is connected to a power
supply.
Make sure that all voltage sources (supply and process voltage) are switched
off before you
– connect or disconnect any signal or terminal block
– remove or replace a module.
NOTICE!
Risk of damaging the PLC modules!
Overvoltages and short circuits might damage the PLC modules.
– Make sure that all voltage sources (supply voltage and process supply
voltage) are switched off before you begin with operations on the system.
– Never connect any voltages or signals to reserved terminals (marked with
---). Reserved terminals may carry internal voltages.
The module provides several diagnosis functions Ä Chapter 1.6.2.1.4.6 “Diagnosis”
on page 388.

The output signal is undefined if the supply voltage at the L+ terminal is below
10 V. This can, for example, occur if the supply voltage has a slow ramp-up /
ramp-down behavior and must be foreseen when planning the installation.
If the output is configured in current mode, the voltage output signal is unde-
fined and must not be connected.
If the output is configured in voltage mode, the current output signal is unde-
fined and must not be connected.
