5.0 LPI-10
5.1 General Warnings
The LPI-10 is a regulated power supply, designed for use in single-phase AC power
networks. Furthermore, it is a built-in device, so that it is intended for installation in a
distribution box or control cabinet. You must comply with the relevant DIN/VDE
regulations or the regulations that apply to your country when installing the device.
You must connect the supply voltage in compliance with VDE 0100 and VDE 0160.
You must provide a protective device (fuse) and a power supply disconnecting
device.
Correct and safe operation of this device requires proper transport and professional
storage, assembly and installation.
5.1.1 Risk of Electric Shock
Operation of electrical devices inevitably requires that certain parts of these devices
carry hazardous voltage. Improper handling of these devices can therefore result in
death or serious bodily injury, as well as in considerable property damage.
5.2 LPI-10 (Version: open printed circuit board with external plug-in power supply)
5.2.1 Method of Operation
You need at least one LPI-10 for each network segment in order to supply the
LockNodes. The LIP-10 also needs a separate supply voltage of 48 Volts DC.
There are two models available for this, depending on the size of the network:
 LPI-10 with 48V plug-in power supply for max. 40 LockNodes
 LPI-10 with 48V plug-in power supply for max. 62 LockNodes
Larger networks use proportionately more LPI-10 modules.
