2.6.4 Connection and wiring
For detailed information such as technical data of your mounted devices (AC500 product family)
refer to the hardware device description of the appropriate device.
NOTICE!
Attention:
The devices should be installed by experts who are trained in wiring electronic
devices. In case of bad wiring, the following problems could occur:
–
On the terminal base, the terminals L+ and M are doubled. If the power
supply is badly connected, a short circuit could happen and lead to a
destruction of the power supply or its fuse. If no suitable fuse exists, the
terminal base itself might be destroyed.
–
The terminal bases and all electronic modules and terminal units are pro-
tected against reverse polarity.
–
All necessary measures should be carried out to avoid damages to modules
and wiring. Notice the wiring plans and connection examples.
NOTICE!
Attention:
All I/O channels (digital and analog) are protected against reverse polarity,
reverse supply, short circuit and continuous overvoltage up to 30 V DC.
NOTICE!
Attention:
Due to possible loss of communcation, the communication cables should be
fixed with cable duct or bracket or clamp during application.
2.6.4.1
Power supply
As soon as the power supply of the processor module (CPU) is higher than the minimum
Process and supply voltage (see
Chapter 2.6.1.1 “Environmental conditions” on page 971
the power supply detection is activated and the processor module is started. Power supply
of processor module and I/O modules should be powered on the same time, otherwise the
processor module will not switch to run after startup.
When during operation the power supply is going down lower than the minimum Process and
supply voltage (see
Chapter 2.6.1.1 “Environmental conditions” on page 971
) for more than
10 ms, the processor module is switched to safety mode (display shows “AC500”). A restart of
the processor module only occurs by switching the power supply off and on again.
If an I/O module is disconnected during normal operation from power supply while processor
module is still powered, the processor module will continue its normal operation on all other
powered peripherals (I/O modules, communication modules and communication interfaces), but
freezes the input image. After recovery of I/O Module power supply it will continue normal
operation and inputs and outputs were updated.
Logic Controller Supply: AC500 logic controller power supply is provided through terminals L+ /
M.
Process Power Supply: S500 process power supply is provided through terminals UP / ZP.
Logic Controller Supply is galvanic isolated from Process Power Supply.
As system power supply for AC500/S500, the ABB CP power supply series can be used.
