Information
Larger terminal blocks may be used to group multiple signals. The current
carrying capacity of the terminal block is thus, however, reduced (according
to derating curve of the terminal block manufacturer.)
The technical data for the terminals are contained in the technical data
sheet of the manufacturer of the female connectors.
17.4 Connections and wiring
CAUTION!
• When switching off the control, the power supply of the module must be
disconnected before or at the same time as the power supply of the
CPU module. In case of non-observance the outputs of the module may
have undefined states for a short time
17.4.1 Power Supply
!
WARNING!
Danger of personal injury due to electric shock!
• Supply the device exclusively from power sources that have an extra
low voltage (e.g. SELV or PELV according to EN 61131 2:2007)
• Connect only voltages and power circuits to connections, terminals and
interfaces up to 50 V rated voltage that have a secure disconnect for
hazardous voltages (e.g. with sufficient isolation).
