The internal power supply voltage for the module's circuitry is carried out via the I/O bus
(provided by a communication interface module or a CPU). Thus, the current consumption from
24 V DC power supply at the terminals UP/L+ and ZP/M of the CPU/communication interface
module increases by 5 mA per AI563.
The external power supply connection is carried out via the UP (+24 V DC) and the ZP (0 V DC)
terminals.
NOTICE!
Risk of imprecise and faulty measurements!
Analog signals may be distorted seriously by external electromagnetic influ-
ences.
Use shielded wires when wiring analog signal sources. The cable shield must
be grounded at both ends of the cable. Provide a potential equalisation of a
low resistance to avoid high potential differences between different parts of the
plant.
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.
