INDICATION
The battery drawers must always be added/removed in multiples of 4 (1 KB consists of four battery drawers for
models with internal battery or external modular battery units). If a KB is added, start from the free slots at the
bottom and covered with the plastic covers of the kit 3 108 65. If a KB is completely removed, cover the free slots with the
empty battery slot covers of the kit 3 108 65.
If the installation/removal procedure changes the total number of KB installed in the UPS, it is necessary to update this
setting from the control panel.
After concluding the installation/replacement operations, calibrate the batteries through the control panel to get precise
indications regarding the total autonomy of the UPS.
To perform this operation, enter the main menu and follow the path Tools Batteries Batt. Calibration.
Press the ENTER key to confirm the choice.
INDICATION
Always replace only 1 KB at a time
7.5.1 Installation/replacement of battery drawers with UPS on-line
If the UPS has more than 1 KB every 10kVA of power supplied on the output, it is possible to replace 4 battery drawers (1
KB) a time with the UPS functioning on-line.
This operation can be carried out on models with internal batteries and on modular Trimod HE BATTERY.
The replacement procedure is the following:
1. Check that the UPS has installed more than 1KB every 10kVA of power supplied.
2. Check that the UPS is not functioning in battery mode and that the battery charger is in the "maintenance" or "standby"
state.
To check the status of the battery charger, go into the menu UPS Status Measures Batteries and check the
fourth item shown on the screen.
3. Extract the four battery drawers relative to just one KB. To add another KB, do not remove any battery drawer.
4. Insert the four new battery drawers and fix them with the screws provided with them.
5. Repeat steps 2, 3 and 4 for every KB to install/replace.
INDICATION
If the UPS switches to battery mode during the operation, do not extract nor insert battery drawers. It is possible to
resume the operation when the UPS returns to the on-line mode.
If during the operation the input mains power fails, the autonomy is reduced: it is therefore necessary to carefully assess
this circumstance in relation to the application before beginning the procedure.
7.5.2 Installation/replacement of battery drawers with UPS in maintenance manual bypass
This procedure is valid for both models with internal batteries and for modular Trimod HE BATTERY.
1. Check that the procedure for placing in maintenance bypass mode described in paragraph 7.4.1 has been applied.
2. Extract the four battery drawers relative to just one KB. To add another KB, do not remove any battery drawer.
3. Insert the four new battery drawers and fix them with the screws provided with them.
4. Repeat steps 2 and 3 for every KB to install/replace.
5. To leave the manual maintenance status actuate the procedure described in paragraph 7.4.1.
CAUTION
During maintenance bypass operations, the load is not protected because it is supplied from the bypass input line.
7.6
Extraordinary maintenance
Contact the LEGRAND Technical Support Service if there are failures that require the access to internal parts of the UPS.
