5.2.6 Return from Manual Bypass to normal Operation
This procedure describes how to start the UPS and how to transfer the load from the maintenance bypass to the UPS
inverter.
Hinet is restored back to operation after connecting the Maintenance (manual) by-pass switch in the following order:
1. switch on INPUT RESERVE switch ?;
2. switch on INPUT MAINS switch ?;
3. switch on BATTERY fuses switch ?;
4. switch on OUTPUT switch ?;
5. switch off MAINTENANCE BYPASS switch (manual);
6. switch on the inverter, pressing ENTER in the INVERTER ON-OFF display
