CHAPTER 8 - CFW-09 OPTIONS AND ACCESSORIES
ENCODER CONNECTION: Refer to item 8.2.
INSTALLATION
The EBA 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 (6A, 7A, 10Aand 13
A/220-230 V and 3.6A,
4A, 5.5Aand 9A/380-480 V) the plastic cover must be removed to install the
EBAboard.
Mounting Instructions:
1.
Set the board configuration via S2 and S3 dip switches (Refer to
t
able 8.2);
2.
Carefullyinsert terminalblock XC3 (EBA) into the female connector XC3
of the CC9 control board. Check that all pins fit in the XC3 connector;
