Cumberland EDGE 2 System - Page 26

Chapter 2: Pre-Installation Planning
WARNING
The maximum distance of the DC power cable is 500ft (150m) with a wire of 16AWG
from the EDGE Expansion Box to the last EDGE 2 Controller on the EDGE network.
Over this distance, use an EDGE PSU 24V 36W to supply power to the EDGE 2
Controllers. In this case, do not use the 24Vdc from the EDGE Expansion Box.
Figure 2-1 Distance > max. distance with 16 AWG — no redundant power
EDGE 2 Controller Screenless
The EDGE 2 Controller Screenless can be used only as a Redundant Main Controller in a redundancy
system scheme.
NOTE: Use only Ethernet cables with EDGE 2 Controller Screenless for Ethernet network. The router
must have DHCP function when using this type of controller.
EDGE 2 Remote Display
Use the EDGE PSU 24V 36W to power the EDGE 2 Remote Display. This will make sure the EDGE
Expansion Box power supply is not overcharged.
The EDGE 2 Remote Display needs an EDGE 2 Main Controller to control the EDGE system indirectly.
An EDGE network without a Main Controller is impossible.
