THE CONNECTION BETWEEN THE UPS AND THE BATTERY BOX MUST BE MADE WITH THE DEVICES
SWITCHED OFF AND UNPLUGGED FROM THE MAINS
UPS SHUTDOWN PROCEDURE:
¾
Turn off all the devices connected to the USP, or use (if installed) the remote bypass option.
¾
Turn off the UPS following the correct procedure (see “Switching off the UPS”, in the “USE” section).
¾
Open all isolators and fuse holders in the UPS.
¾
Isolate the UPS completely from the mains power supply, by opening all the external protection devices located on the
input and output lines.
¾
Wait a few minutes before working on the UPS.
¾
Remove the UPS terminal cover (see “Operations to access the terminals of the UPS").
CONNECTING THE BATTERY BOX:
¾
Make sure that the battery voltage of the Battery Box corresponds to that allowed by the UPS (check the data plate on
the Battery Box and the UPS manual)
¾
IMPORTANT:
make sure that SWBATT fuse holders of the UPS and Battery Box are open.
¾
Before making any connection read carefully the instructions in the Battery Box manual.
¾
Connect the cables coming from the Battery Box to the UPS terminal board (see figure below), making sure to respect
the polarisation. The first connection to be made is that of the yellow-green protection cable.
¾
Once all these operations have been carried out, replace the previously removed terminal covers on the UPS and on
the Battery Box
CHECKING INSTALLATION:
¾
Insert the fuses in the SWBATT fuse holders of the Battery Box.
¾
Close the SWBATT fuse holders of the Battery Box and the UPS.
¾
Carry out the UPS start-up procedure indicated in this manual.
¾
After about 30 seconds, check that the UPS is operating correctly: simulate a black-out by opening the SWIN input
isolator of the UPS. The load should continue to be powered, and the “battery power” LED should light up on the UPS
control panel. The latter should beep at regular intervals. Once the SWIN input isolator has been closed again, the
UPS should resume operating on mains power.
