Use only compatible options. Connect the SI-N3 to CN5-A. For other option connections refer
to the Installation Manual for those options.
Option Fault (CN5-B)
oFb02
Two of the same option are connected simultaneously.
Only one of these options, AI-A3, DI-A3 or SI-
same time. The SI-N3 must be connected to CN5-A.
Non-Compatible Option connected to drive port CN5-C
oFc00
