2 INSTALLATION

XC25 Terminals
1 STO1
2 GND1
3 STO2
4 GND2
NOTE!
Both input circuits (for K1 and K2) are electrically isolated from each other. XC25:2
and XC25:4 terminals are not connected internally to inverter +24 V power supply
reference. In most of cases, those terminals are connected to XC1:11 control terminal
in CFW-11 and CFW-11M inverters and to XC1:36 in CFW70X inverters.
NOTE!
Follow the instructions provided on Chapter 3 INSTALLATION AND CONNECTION
of User's Manual.
For XC25 control cabling consider the following:
Use wire gauge from 0.5 mm
„
torque of maximum 0.50 N.m (4.50 lbf.in).
Use shielded cables connected to ground only on inverter side (use the provided metallic
„
pieces as shown on
Run the cables separated from the remaining circuits (power, 110 V/220 Vac control, etc.).
„
It is recommended not to exceed 30 m of cable length.
