Summit WM20 Controller
WARNING!
You should avoid operating the Summit WM20 Controller in a LAN in which the DC volatage is overlaid on the data
lines because the LAN may have switches that connect directly without checking the supply voltage. Depending
upon the transformer at the LAN interface, voltages of upto 500 Volts can be induced. Such peak voltages can
destroy the physical LAN controller’s logic.
NOTE
The Summit WM20 Controller can operate with either 110 or 230 V AC.
No electrical connection exists between the Wireless Access Points (Wireless AP) and the Summit
WM20 Controller. The Summit WM20 Controller and the Wireless AP communicate with each other via
the IP network. For more information, see the Summit WM20 User Guide.
