XC25 Terminals
Function
Specifications
1
STO1
Terminal 1 of safety relay K1 coil
Coil rated voltage: 24 V, range: 20…30 Vdc
Coil resistance: 960 Ω ± 10 % @ 20 °C (68 ºF)
2
GND1
Terminal 2 of safety relay K1 coil
3
STO2
Terminal 1 of safety relay K2 coil
Coil rated voltage: 24 V, range: 20…30 Vdc
Coil resistance: 960 Ω ± 10 % @ 20 °C (68 ºF)
4
GND2
Terminal 2 of safety relay K2 coil
NOTE!
Terminals XC25: 2 and XC25: 4 are not internally connected to the reference of the inverter power
supply +24 V. These terminals are often connected to the control terminal XC1:11.
NOTE!
Follow recommendations of
Item 3.2.5 Control Connections on page 3-29
.
For XC25 control cabling considers the following:
Use wire gauge from 0.5 mm2 (20 AWG) to 1.5 mm2 (14 AWG) and maximum tightening 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
Figure 3.21 on page 3-35
.
Run the cables separated from the remaining circuits (power, 110 V / 220 Vac control, etc.).
