Notes on electrical installation
IMPORTANT
Device damage due to incorrect supply voltage!
An incorrect supply voltage may result in damage to the device.
• Only operate the device using a protected low voltage and safe electrical insulation
as per protection class III.
IMPORTANT
Equipment damage or unpredictable operation due to working with live parts.
Working with live parts may result in unpredictable operation.
• Only carry out the wiring when the power is off.
• The voltage supply must be disconnected when attaching and detaching electrical
connections.
•
Only qualified electricians are allowed to perform the electrical installation work.
•
Always comply with standard safety requirements when working on electrical sys-
tems.
•
Only switch on the supply voltage for the device when all connections have been
established and the wiring has been thoroughly checked.
•
When using extension cables with flying leads, make sure the bare wire ends do
not touch (risk of short-circuit when the supply voltage is switched on). All cables
must be properly insulated from each other.
•
The wire cross-section of the supply cable from the user’s voltage supply system
must be designed in accordance with the applicable standards. In Germany, the
following standards must be observed:
DIN VDE 0100 (Part 430) and DIN VDE 0298 (Part 4) or DIN VDE 0891 (Part 1).
•
Circuits connected to the device must be designed as circuits with safety extra-low
voltage (SELV) and protective extra-low voltage (PELV).
•
Protect the device with a separate fuse at the input of the supply circuit.
NOTES REGARDING the layout of data cables:
• Use only shielded data cables with twisted wires.
• Make sure that the shielding is correct and complete.
• To avoid interference, e.g., from switching power supplies, motors, clocked drives
and contactors, always use suitable EMC cables and layouts.
• Do not lay cables in cable ducts in parallel with voltage supply cables or motor cables
over longer distances.
The IP67 and/or IP69 enclosure rating of the device is only achieved under the following
conditions:
•
The cable connected to the M12 connection is screwed tight.
If this is not the case, the device will not meet the specified IP enclosure rating.
