5.3 Installation lines
5.3.1 Power supply line
Power can be supplied in the following ways:
• From the host control device (power supply and data line in one cable)
• From a separate power supply
NOTICE
Voltage drops, caused by line resistance, must be taken into consideration for
long lines.
The given cable types and diameters are examples and serve as recommendations.
The technical specifications of the cable manufacturer are authoritative for the pre-
cise determination of the cable diameter/cross section and the resulting maximum
cable lengths. The voltage drop across the cable length is decisive in this case. As
such, the voltage that is available at the end of the cable may, under no circum-
stances, be less than the minimum permitted supply voltage of the connected com-
ponents. This always applies in consideration of the maximum power consumption
of the connected components.
Only connect the terminals when the power is switched off.
Notice: The device may only be supplied with SELV (Safety Extra Low Voltage) and
LPS (Limited Power Source), according to IEC/UL/CSA 60950-1.
5.3.1.1 Power supply from the host control device
(Central power supply)
Power is supplied from the host control device.
In the case of bus wiring, the power supply and data line can be carried in one cable
(maximum total length of 350m).
In the case of star wiring, the power supply and data line can be carried in one cable
(maximum length per stub of 20m).
A separate power supply must be used for greater distances.
