5.2 AC power cable
5.2.1 Introduction
The Alternating Current (AC) power cable ranges from 85 V AC to 264 V AC and 50/60 Hz.
The power cable transmits the AC to the terminal block of the Secure Router 8012 power
module to supply power to the entire Secure Router 8012.
Nortel recommends that you use the grounding single-phase three-line power supply. The
grounding point of the power supply in the building must be reliable grounding. The power
grounding cable of the power supplying system is buried in the ground during the
construction of the building. You must ensure that the power supplies are grounded before you
connect the AC power cable of the Secure Router 8012 routers.
