3.3.1 Installation
NOTE!
The inverter must be installed inside an IP54 panel (at least).
Table 3.25: Signals from the terminals XC25 (terminals for Safety Stop)
Connector XC25 Function Specifications
1 STO1 Terminal 1 of the coil of relay 1
Coil rated voltage: 24 V, range from 20 to 30 Vdc
Coil resistance: 960 Ω ±10 % @ 20 °C (68°F)
2 GND1 Terminal 2 of the coil of relay 1
3 STO2 Terminal 1 of the coil of relay 2
Coil rated voltage: 24 V, range from 20 to 30 Vdc
Coil resistance: 960 Ω ±10 % @ 20 °C (68°F)
4 GND2 Terminal 2 of the coil of relay 2
NOTE!
Follow the recommendations of Item 3.2.12 Control Connections on page 3-29 .
For control cabling XC25 consider:
„
Use gauge from 0.5 mm² (20 AWG) to 1.5 mm² (14 AWG) and maximum tightening torque of 0.50 N.m (4.50 lbf.in).
„
Use shielded cables connected to the ground on the inverter side only. Use the metal parts supplied as shown
in
Figure 3.49 on page 3-44 .
„
The cables must run separately from the other circuits (power, control 110 V / 220 Vac, etc.).

Safety Stop
Function
Inverter Behavior
0 (0 V) 0 (0 V)
Activated
(enabled)
The inverter remains in the STO state and does
not accept commands. To leave such condition,
it is necessary to have STO1 = 1 and STO2 = 1
simultaneously
0 (0 V) 1 (24 V)
Fault
The inverter is tripped by fault F160 (fault related
to the Safety Stop). To leave this condition, it is
necessary to reset the inverter
1 (24 V) 0 (0 V)
1 (24 V) 1 (24 V) Disabled The inverter accepts commands normally
NOTE!
Maximum delay between signals STO1 and STO2: 100 ms (otherwise, fault F160 will occur).
The Safety Stop function has priority over the other functions of the inverter.
This function must not be used as control to start and/stop the inverter.
