because it is for the V Series model 3000.
Do not use it alone or for other applications.
Failure to observe this can cause electric
shock, injuries or module trouble.
6F8C0904 iii
Mandatory
1.In configuring a system using 10BASE5,
make sure not to exceed the maximum
cable length of 500 m per segment and the
maximum number of MAUs(100)
2.In configuring a system using 10BASE5,
make sure that MAU intervals will not be
less than 2.5 m.
3.In configuring a system using 10BASE5,
make sure that AUI cable length will not
exceed 50 m.
4.Configuring a system using 10BASE5
requires MAU and AUI cables.(See 3.6
Network Component.) Purchase them as
necessary for your system.
Mandatory
1.In configuring a system using 10BASE2,
make sure not to exceed the maximum
cable length of 185 m per segment and the
maximum number of MAUs (30).
2.In configuring a system using 10BASE2,
make sure that node intervals will not be
less than 0.5 m.
3.Configuring a system using 10BASE2,
requires terminators and T-adaptors. (See
3.6 Network Components.) Purchase them
as necessary for your system.

it is difficult to simultaneously switch
external power and T3H power on/off,
observe the following sequence.
Switching power on: T3H power first,
then external power
Switching power off: External power
first, then T3H power
Failure to observe the above sequence of
switching power on/off could cause trouble,
malfunction and/or shortcircuit.
Mandatory
1.ASK a qualified company for 10BASE5/
