Prerequisites:
All of the following requirements are complied with:
•The supply voltage corresponds to the voltage specified on the type plate of the device.
•The power supply complies with the requirements for a safety extra-low voltage (SELV) according
to IEC60950-1 or ES1 according to IEC/EN62368-1.
•The power supply has an easily accessible disconnecting device (for example a switch or a plug).
This disconnecting device is clearly identified. So in the case of an emergency, it is clear which
disconnecting device belongs to which power supply cable.
•The wire cross-section of the power supply cable is at least 0.75mm2
(North America: 18AWG)
on the supply voltage input.
The wire cross-section of the power supply cable is at least 1mm2 (North America: 16AWG) on
the supply voltage input for PoE device variants.
•The cross-section of the ground conductor is the same size as or bigger than the cross-section of
the power supply cables.
•There are fuses suitable for DC voltage in the positive conductors of the supply lines, or the volt
age sources are appropriately current-limited. Regarding the properties of this fuse:
See Supply voltage 24VDC on page 58
See Supply voltage 48VDC(PoE) or 54VDC (PoE+) on page 59
•The negative conductors of the voltage inputs are on ground potential.
•For PoE device variants LRS32, LRS42, LRS42-HP, the power sources are electrically isolated
from the ground potential. According to specification IEEE802.3, the insulation voltage must be
1500VAC or 2250VDC. For non-PoE device variants LRS30, and LRS40, there is no need of iso
lated power at the input.
