Installation and cabling
5.1.
Introduction
Installation and cabling of the IPC/RSL8 system has to be done with great care; the correct
cabling is essential for high operational reliability and the correct grounding is necessary for
protection. To meet the requirements of "CE"-certification all cables have to be shielded. The
enclosure has to be connected to ground via the DIN-rail or mounting kit.
Important note
Before applying power to the RSL8 system, the main board must be configured
correctly.
Important notes
To meet the requirements of EMI/RFI "CE"-certification, correct mounting, installation
and cabling of the RSL8 system according to these guidelines is absolutely necessary.
5.2.
Powering the RSL8 System
The "logic supply voltage", i.e. the power driving the electronic circuits (CPU and base board)
is internally generated from the 24VDC power supply input. Remember that the power supply
is isolated. For a non-isolated version please contact the manufacturer.
The power supply has to be connected according to paragraph 3.3.12. Maximum allowed cable
length between ac/dc power supply and system power input is 30 m. If the cable is longer than
30 m or routed outside the building, special overvoltage and filtering elements have to be
installed to comply with the requirements of EMI/RFI "CE"-certification. Use
AWG18/0.75mm
2
wires at minimum to comply with the safety requirements and follow the
connector manufacturers instruction guide.
When selecting the external power supply the maximum power dissipation of the system has to
be considered.
Important notes
Please make sure that the input voltage does not exceed the recommended operating
range otherwise the electronics board could get damaged and correct operation cannot
be guaranteed.
Use an overload protected power supply to prevent damage in case of a short inside the
system.
The ac/dc power supply must fulfill the requirements for EMI/RFI "CE"-certification.
