ATTENTION!
The isolation of the analog input AI3 and the analog outputs AO1
designed only to interrupt the ground loops. Do not connect these inputs to
high potentials.
ENCODER CONNECTION: Refer to item 8.2.
INSTALLATION
The EBB board is installed on the CC9 control board, secured with spacers
and connected via Terminal blocks XC11 (24 V) and XC3.
NOTE!
For the CFW-09 Size 1 Models (6 A, 7 A, 10 A and 13 A / 220-230 V and 3.6 A,
4 A, 5.5 A and 9 A / 380-480 V) the plastic cover must be removed to install the
EBB board.
