(Nodes)

• The M-RESTER is applicable to networks which consist only of FTT-10A.

Not applicable to the ones connected to Link Power network.

• The maximum number of nodes connectable to the network segment is reduced by one

when one unit of M-RESTER is added.

• When the distance between nodes are relatively long (e.g. grouped and separated by cabinets),

install the M-RESTER by each group of devices. Insert the M-RESTER at the surge side of the network.
