CAUTION
Do not short-circuit terminal P24 to either 11
or CM. Damage may result.
NOTES
1 Terminal DB not available for VXS20-1.
2 Input to terminal THR, (N/C contact)
from external protection relay.
TRIP/ALARM RELAY
Relay is shown with the inverter in either the
power-off or power-on state, condition
‘healthy’.
5.4 Terminals Functions List continued
Terminal Terminal Function Description
Control Outputs
Y1E Open emitter output; 50mA max.
Six different functions are available according to
preset selection; refer to Function 54.
CMC Reserved for Y1E output only Refer to the illustration on page 13.
30A, 30B,
When no trip, N/O circuit 30A-30C; N/C circuit
30C
Alarm output, all trips 30B-30C. When inverter trips, 30A-30C closes.
Rating 48V DC, 0.3A.
