How many types of Electrode Separators are there, and how are they mounted?

There are three types: F03-14 1P, F03-14 3P, and F03-14 5P.
They are mounted to the coupling part of 1-m Electrodes.
F03-14 1P is a one-pole type and there are no restrictions on its mounting intervals, so any Electrode Holder can be used.
F03-14 3P and F03-14 5P can be used only with PS-[]S Electrode Holders.
