range from about 2 MHz up to about 28 MHz. By the same token, the device demodulates
the data telegrams it receives from the other end.
1.3
Rated conditions
●
The operation of Power Line Booster devices in public supply networks is not permitted.
●
The operation of standard powerline components in the PLB system environment is not
permitted, because real-time requirements can no longer be guaranteed in this case.
●
Only devices that are connected to a PLB master can communicate with devices that are
connected to a PLB slave. Inter-device communication, that is, direct data exchange,
between devices connected to different PLB slaves is not possible.
●
We recommend operating the Power Line Booster in a separate communication network.
1.4
Insulation
The Power Line Booster or Power Line Booster system is intended for operation in low
voltage systems with up to 500 V AC. The recommended components require that all
voltages within the system are within the following limits:
●
Low voltage: Max. 500 V AC +15% line-to-line voltage with symmetrical ground
This high limit applies to the system supply lines, e.g. L1, L2, L3 (not for the
communication cables), and refers to the insulation system of the PLB system.
●
Extra-low voltage: Max. 42 V AC +15%
This restriction applies to the communication cables. Operation of the system is also
possible when these rails or cables are de-energized. Operation is not possible when
both communication cables are short-circuited.
●
PLB supply voltage: 24 V DC ± 20%
The power supply unit for the supply voltage of the Power Line Booster must meet the
"Safety Extra Low Voltage" (SELV) or "Low Voltage / Current" (LV/C) specification. The
device cannot be supplied over the communication cables.
