5.5.1 Power supply specifications
Please refer to the Instruction Manual Power Supply PSU RF SERIES 15VDC-60W for
information and safety instructions of this power supply.
5.5.2 Power supply restrictions
Local laws and regulations must be respected when installing and servicing this device.
A maximum of three (3) RF Mono antennas can be powered using one (1) power supply.
The RF mono antenna, to which the power supply is connected directly, will distribute the
power through the Field bus (UTP cable). When an RF Mono receives the power through
the UTP cable, it will not apply power to the next antenna.
It is not necessary to install separate power supply wiring, as the power supply is
distributed by the UTP cable to the next antenna.
