Preparing the electrical installation
5.3.1
Supply voltage
DC 24 V ±15% as per IEC 60364-4-41 (pay attention to permitted cable lengths in
tab. 12
on page 47
)
The NAV350 draws the following power:
•
on switching on without switching outputs wired maximum 36 W
•
in operation typically 12 W, plus a maximum of 12 W with switching output wired
The supply of power/the external power supply for the supply of power must be able to
provide at least 40 W continuous power, if the switching output is wired at least 48 W
continuous power.
