OverVoltage to the earth when Voltage is over 230V.

as you know that the voltage for
Cat5e Patch Panel,Cat6 Keystone Jack
the PBX and PSTN is lower than 230V for its
own operation voltage,
the LPU will only work

the PBX and PSTN is working
well,why the LPU will provide the Overvoltage Protection?
If your PBX and PSTN is 130/140/150V type,and you need the LPU provide the

protections at this Voltage,we could make the tolerate Voltage and its
working OverVoltage protection at 130V,this is ok.Install the Disconnection module on
