Programmable relay contacts Relay output
240VAC - 6A resistive load
Contact closed when :
- the inverter is switched on and not tripped
(b50 = 0),
- the inverter is not faulty and the frequency is
above P0 (b50 = 1).
A3 Programmable output Logic output
24VDC - 100 mA open collecter
Output at 0V when :
- the inverter is running (b53 = 0),
- when the frequency is at a minimum (b53 = 1).
Connect a 24VDC relay between A3 and A4.
