Summit WM Controller WM200/2000 maintenance

WARNING!
The Summit WM Controller WM200/2000 system may not be operated in a LAN in which a DC voltage is overlaid
on the data lines, since there are still switches that connect directly without checking the supply voltage first.
Depending on the transformer at the LAN interface, voltages of up to 500 V can be induced. Such peak voltages
usually lead to destruction of the physical LAN controller's logic.
