Preparation for electrical installation
5.3.1
Supply voltage
The user will require the following to commission and operate the NAV210:
NAV210
•
10.8 to 30 V DC according to IEC 60 364-4-41
The NAV210 consumes the following:
•
Power consumption of the NAV210 with maximum output load of 20 W
•
Power consumption of the NAV210 with maximum heating power of 60 W
5.3.2
Wire cross-section
▸
All connections must be wired with copper cables.
▸
Use the following wire cross-sections:
•
Supply voltage: at least 0.25 mm² if local power supply (power supply unit) is in the
immediate proximity
•
Supply voltage: at least 1.0 mm² with a maximum length of 20 m when connected to
available 24 V DC network
•
Switching outputs: at least 0.25 mm², maximum length of cable 50 m at 0.5 mm²
•
Data interface: at least 0.25 mm²
•
With the NAV210, the external diameter of the joint cable must not exceed 9 mm due to
the cable entry.
Important
If you use flexible connecting cables with strands to connect to the terminals of the NAV210,
then you do not have to use ferrules.
5.3.3
General requirements of the data interfaces
The following table shows the maximum recommended lengths of cables depending on the
selected data transmission rate.
Table 11: Maximum lengths of cables for the data interfaces
Important
•
Use shielded cables (twisted pairs) with at least 0.25 mm².
•
To prevent interference factors, do not lay data cables over a longer route in parallel with
power supply cables and motor cables, in cable channels, for example.
WARNING:
Use safety transformer
There must be safe electrical separation between the output current circuit of the
power supply and the input current circuit. This is usually generated by a safety
transformer conforming to the IEC 742 standard (VDE 0551).
