4.3 Additional 3X AS400 Interface (# 100201120008)
This board is connected (piggy back style) directly via connector X1
on to the Interface board connector X2 of # 100201120003, in the
same place of # 100201120007. This board can only be used in
conjunction with the Interface board # 100201120003.
It is not possible to fit both # 100201120007 and #
100201120008 boards.
The Additional 3 x AS400 Interface connects the UPS upto three IBM
AS400 computers, all they are totally insulated (ground and signals).
Alarm logic and contact rating are the same as the section AS400 of
#100201120003. This circuit is repeated 3 times on #
100201120008 so it possible to connect upto 4 AS400 to the UPS.
