NOTE!
If the degree of protection of the used inverter is lower than IP54, it must be installed inside an IP54
(minimum) cabinet.
Table 3.15 - XC25 terminals (Safety Stop terminals) signals
XC25 Terminals Function Specications
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 3-45.
For XC25 control cabling considers the following:
Use wire gauge from 0.5 mm
2
(20 AWG) to 1.5 mm
2
(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 3.41 on page 3-51.
Run the cables separated from the remaining circuits (power, 110 V / 220 Vac control, etc.).
