Notes on the electrical installation
IMPORTANT
Equipment damage due to incorrect supply voltage!
An incorrect supply voltage may result in damage to the equipment.
• 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 wiring work when the power is off.
• Only connect and disconnect electrical connections when the power is off.
•
The electrical installation must only be performed by electrically qualified person
-
nel.
•
Standard safety requirements must be met when working on electrical systems.
•
Only switch on the supply voltage for the device when the connection tasks have
been completed and the wiring has been thoroughly checked.
•
When using extension cables with open ends, ensure that bare wire ends do not
come into contact with each other (risk of short-circuit when supply voltage is
switched on!). Wires must be appropriately insulated from each other.
•
Wire cross-sections in the supply cable from the user’s power system must be
designed in accordance with the applicable standards. In Germany, observe the
following standards:
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 SELV circuits
(SELV = Safety Extra Low Voltage).
•
Protect the device with a separate fuse at the start of the supply circuit.
Notes on layout of data cables:
•
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 over long distances in parallel with voltage supply cables and
motor cables in cable channels.
The IP 67 enclosure rating for the device is only achieved under the following conditions:
•
The cable on the M12 connection has been screwed on.
If this is not done, the device does not fulfill any specified IP enclosure rating!
