EPLACEMENT OF THE BATTERY PACK
As indicated in the presentation, the UPS is provided with a dedicated battery pack that permits easy
replacement of the batteries (hot swap), entirely safely for the operator, thanks to the protected connection
system.
WARNING: for your own safety and that of your product, it is important that you follow the instructions
given below exactly.
WHEN THE BATTERY PACK IS DISCONNECTED, THE LOADS CONNECTED TO
THE UPS ARE NOT PROTECTED AGAINST A MAINS FAILURE.
THE BATTERY PACK IS VERY HEAVY. TAKE ALL DUE CARE WHEN
PERFORMING SUBSTITUTION.
1 - The battery pack is located behind the front panel of the UPS. Take the
panel centrally by the sides and pull gently outwards as shown in the
figure to the side. In doing so, do not force the panel fastening pins too
much.
2 - Put the manual bypass switch located under the front panel to position
“II” (see figure to the side).
WARNING: in this condition, the load is powered by the bypass and
the display must show the message FAULT: C02.
WARNING: For proper operation of the UPS, it is recommended that
you replace the battery pack only with the UPS switched on.
3 - The battery pack is connected to the rest of the UPS by means of a
cable with terminal. See the figure on the side:
press the 2 tabs on the sides of the terminal ( A ) and take it out
pulling gently upwards. With your thumbs, together press the 2
fastening catches (
B ) and, keeping them pressed, put your index
fingers into the slot located under the connector ( C ).
4 - Maintaining the position described in the previous step, take out the
battery pack pulling outwards as shown in the figure to the side.
Take great care when extracting the battery pack as it is very heavy.
WARNING: the new battery pack and the one to be replaced must
contain the same number and type of batteries (see the label next to the
connector on the battery pack).
5 - Insert the new battery pack in its seat by sliding until it clicks into the
UPS. Connect the cable with terminal again to its connector, put the switch back to position “I” and
close the front panel. Make sure that the display returns to the normal display mode.
