Connectlng
the
AIPUE
to
an
AWU
Although the A8PUE can be connected
to
an ACPU even while it is running,
Mitsubishi recommends connecting
the
ABPUE
to
an ACPU while it is in the
STOP state.
If
it must be connected while
in
the RUN state, make sure
to
insert the connector properly.

Connection using the add-on method
In this method, the A8PUE is installed directly onto the ACPU module.
However, the add-on method cannot
be
used
for
connecting an AIS and
A2CCPU(C24/PRF) because screws cannot be tightened.
Connect then using the hand-held method.
