6.2.4 Isolating One UPS for Service/Maintenance

In a redundant system, one UPS may be isolated for service/maintenance without affecting other UPSs.

1.Check that remaining UPS(s) is capable of carrying the load in the event that one UPS is isolated

2.Switch off system to be isolated for maintenance purposes by pushing green “ON” and red “OFF” buttons simultaneously

3.To disconnect battery, mains and output, open battery MCCB/fuse and set input switch (Q001) and output switch (Q002) to position “0”

With Q002 in position “0”, UPS will be operational and may be tested as a single system without affecting other parallel UPS(s).

H002a

6.2.5 Switching Back to Normal Parallel/Redundant Operation

1.Turn input switch (Q001) and output switch (Q002) to position “1”

2.Charge capacitor, connect battery and start up UPS

UPS will automatically switch to normal operation and start load-sharing with other parallelled UPS(s).

WARNING!

System will discharge built-in capacitors, but check terminal voltage before proceding.
