The procedure described needs no further manual settings via the operator panel; the UPS automatically recognises the
new power module and reconfigures automatically.
As far as identification of the modules is concerned, bear in mind that the first module at the top left is always identified
with zero. The adjacent module is, therefore, number 1 and the others follow in sequence.
9.5.3 Manual exiting from maintenance bypass
To restart the UPS from the maintenance bypass to the On-line status, follow these steps.
1. Ensure that the output disconnector is open and start the UPS, pressing the ON/OFF push button.
2. Wait until the UPS is on completely and the main screen page displayed. In this case the UPS is on but the load is
powered directly by the bypass mains; the message “Manual bypass” appears on the panel. In this condition the
backlit status indicator on the front panel turns orange.
3. Close the output disconnector by putting it in the ON position.
4. Open the manual maintenance bypass disconnector by putting it in the OFF position; the UPS goes automatically to
working on-line.
5. At the end of the procedure the load is powered by the UPS. In this condition the backlit status indicator on the front
panel turns green.
6. Close the Archimod® door.
9.6 Installing/replacing battery boxes
There are two different ways to install/replace Archimod® UPS 20, 40 and 60kVA and Archimod® BATTERY battery boxes.
Please read carefully all the following instructions prior to working on the equipment.
The battery boxes must always be added/replaced in multiples of 3 (1 KB).
Note: if the installation/replacement procedure has altered the total number of KBs installed in the UPS their setting will
need to be updated by means of the front panel.
Once the above steps have been done we recommend a battery calibration in order to know exactly what the UPS’s
total autonomy is.
9.6.1 Replacing battery boxes with the UPS On-line (Hot Swap)
If, in total, the UPS has more than 1 KB for each 10kVA of rated power supplied in output (example: at least 5 KBs for one
Archimod® supplying 40kVA), it is possible to replace the battery boxes 1 KB at a time with the UPS On-line.
This can be done on the Archimod® UPS and on the Archimod® BATTERY.
Remember that 1 KB consists of 3 battery boxes.
The procedure for replacing is the following:
1. Ensure that the UPS has at least 1KB installed for each 10kVA of rated power supplied in output plus one;
2. Ensure that the UPS is not running on battery and that the battery charger is either in the maintenance or standby
status. To check battery charger status, access the UPS Status
➝
Measurements
➝
Batteries menu and check the
fourth item displayed.
3. Extract the 3 battery boxes of just one KB. To add another KB do not remove any battery boxes;
4. Insert the 3 new battery boxes and screw them into place with the screws supplied;
5. Repeat steps 2, 3 and 4 for each KB to install/replace.
If just KB is added simply follow the steps described in points 2, 4 and 5.
ATTENTION
Always replace just 1 KB at a time
Note: if the UPS goes over to running on battery while you are doing this, stop and neither extract or insert any battery
boxes! You can continue when the UPS returns working On-line.
Note: if mains input should fail during the operation, autonomy will be reduced: you will need to carefully evaluate such
an eventuality occurring before you start.
