9.4.3 Battery Drawers
There are two different procedures for installing/replacing battery drawers inside UPS Trimod® and UPS BATTERY Trimod®.
Carefully read all instructions before operating on the equipment.
The drawers batteries must always be added/replaced in multiples of 4 (1 KB).
Note
: if the installation/replacement has changed the total number of KB installed in the UPS, you must update the
number of KB via the front panel.
After completing the procedure above described, we recommand to calibrate batteries in order to get correct informations
about UPS runtime.
If the UPS has more than 1 KB for each 10kVA output power, you can replace 1 KB at a time with UPS Online.
This operation can be done inside UPS Trimod® and/or UPS BATTERY Trimod®.
Remember that 1 KB consists of 4 battery drawers.
The replacement procedure is as follows:
1. Make sure the UPS has installed at least every 1KB 10kVA output power output plus one;
2. Make sure the UPS is not operating on battery and the charger is maintenance or standby state. To check the status of
the charger, enter the state ups -> Measures -> batteries, and check the fourth item shown on the display.
3. Remove the four battery drawers (n° 1KB).
4. Insert the new 4 batteries drawers and secure them with the screws provided;
5. Repeat steps 2, 3 and 4 for each KB to install/replace.
In the case of simple addition of KB is enough to follow the steps 2, 4 and 5.
WARNING
Always replace only 1 KB at a time
Note
: If the UPS switches to battery while you are performing the operation, stop and do not remove or insert battery
drawers! it is possible to resume operation when the UPS returns to work on-line.
Note
: if during the operation mains is missing, you will have a reduced autonomy: you should therefore carefully consider
such cases in relation to the application before starting.
