we should configure the AC power mine (C-class mine) with the
discharge current no less than 20KA.
3
The protection ground of the communications power should share
one group of ground body with the protection ground of the
communication device. When the communication power and the
communication device are at the same equipment room, they should
share the protection ground bar of the same equipment room.
4
AC power port should be added with lightning protection circuit.
5
The positive polarity of -48V DC power (or the negative polarity of
the 24V DC power) should be grounded at the DC power output site.
6
The working ground and PGND of the DC power should share the
same grounding body with the AC device PGND. When the
communication power and the communication device are in the
same equipment room, it is recommended for them to share the
same protection grounding bar in the same equipment room.
