Figure 2.3-2 AC Power Cable
Caution:
The three-pole plug actually used may differ from that in the preceding figure
due to the different standards adapted by countries. Appropriate power cables
will be delivered with the alarm box; otherwise a junction board can be used.
3. Connect the DC power cable of the adaptor to the power supply terminal
that is in the right part of the bottom panel of the alarm box. Connect the
bare wire marked with GND to the -48VRTN terminal block of the power
supply terminal. Connect the other bare wire to the -48V terminal block.
Then fix the bare wires with in-built bolts.
4. According to the installation location of the alarm box and the layout of
the cables, install the PVC cable tray on the wall.
If the other ends of the cables need to be placed at the same place (for
example, inside the cabinet). Lay the PVC cable tray along the wall to
the wiring ladder and then to the cabinet (upper cabling method).
