3.6 Mains power
The power switch on the power supply unit (PSU) of the Nokia MetroSite
EDGE Base Station does not disconnect it from the power network (AC or
DC), but leaves it in a stand-by mode. The switch has two positions: ON and
stand-by. A separate main switch on the site is considered to be the
disconnect device for safety and service purposes.
Follow the national legislation when working with the power supply. The
Nokia MetroSite EDGE Base Station must be permanently wired to a
disconnect device (such as a circuit breaker) in accordance with your current
local and national wiring standards.
All ground connections must be secure and non-removable.
All power cabling must meet the requirements of the appropriate national
standard.
The Nokia MetroSite EDGE Base Station has four power supply options: 230
VAC, 110 VAC, -48 VDC and +24 VDC. The permitted voltage fluctuation for
the different options is presented in Table 5.
It is recommended that the AC mains be protected with a lightning and transient
overvoltage protector (mains wire-in protector). This protection is not included in
the Nokia MetroSite EDGE Base Station.
