outputs.
DIGITAL OUTPUTS
Q1
Multi-function Terminal (Open- collector). 26VDC, ≤100mA.
Default value: Run.
EG
Common ground contact for an open collector (with external
power source).
24 External 24V power source. 150mA maximum output current.
A1
Fault signal output. Sends out alarm signals when the
inverter safety features are activated (AC 250V <1A, DC 30V
< 1A).
-
Fault condition: A1 and C1 contacts are connected (B1
and C1 open connection).
-
Normal operation: B1 and C1 contacts are connected
(A1 and C1 open connection).
