230 VAC
115 VAC
Charging circuit monitoring
For each inverter module in the system (one to three) there is a charging current
monitoring on the ASFC unit. Switch S1 enables the monitoring for inverter 1, S2 for
inverter 2 and S3 for inverter 3. All enabled monitoring circuits must detect current
less than 0.7 A (= capacitor bank nearly full) to allow the release of the switch fuse
locking solenoid and to allow the inverter power switch-on.

Note: The ASFC unit does not control the main contacts of the switch fuse closed
unless at least one of switches S1 to S3 is in enabled position.
