Note, information
Refer to IEC 61131-4, User's Guideline, for general installation instructions to be
complied with to ensure that hardware interface factors and the ensuing noise
voltages are limited to tolerable levels.
Electrical immission safeguard
To eliminate electromagnetic interference, connect the control system to the protective earth
conductor. Practice best cable routing.
Cable routing and wiring
Keep power circuits separate from control circuits:
•
DC voltages
60 V ... 400 V
•
AC voltages
25 V ... 400 V
Common laying of control circuits is possible in the following cases:
•
shielded
data signals
•
shielded
analogue signals
•
unshielded
digital I/O lines
•
unshielded
DC voltages < 60 V
•
unshielded
AC voltages < 25 V
CAUTION
The safe wiring method depends on the application
The safety function may be lost
Safely wire up the signal lines if the application requires it. Take heed of the in-
formation in
►
section 6.
Location of installation
Ensure that temperatures, contaminations, impact, vibration or electromagnetic interference
are no impediment to the installation.
Please also note
►
6.2 Mechanical Installation.
Temperature
Consider heat sources such as general heating of rooms, sunlight, heat accumulation in assem-
bly rooms or control cabinets.
Contamination
Use suitable casings to avoid possible negative influences due to humidity, corrosive gas, liquid
or conducting dust.
Impact and vibration
Consider possible influences caused by motors, compressors, transfer lines, presses, ramming
machines and vehicles.
