THE CONNECTION BETWEEN THE UPS AND THE BATTERY BOX MUST BE MADE WITH THE DEVICES
POWERED OFF AND UNPLUGGED FROM THE MAINS
UPS POWER-OFF PROCEDURE:
Ø
Turn off all devices connected to the UPS or use the remote bypass option (if installed).
Ø
Turn off the UPS following the relevant power-off procedure (see the "USE" section of the "Powering off the UPS"
paragraph).
Ø
Open all the isolators and fuse holders present in the UPS.
Ø
Isolate the UPS completely from the electricity network by opening all the external protective devices situated on the
input and output lines
Ø
Wait a few minutes before proceeding to work on the UPS.
Ø
Remove the terminal cover of the UPS (see "Opening the UPS and the Battery Box").
CONNECTING THE BATTERY BOX:
Ø
Check 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 manual of the UPS)
Ø
IMPORTANT: make sure that the SWBATT fuse holders of the UPS and the Battery Box are open.
Ø
Remove the terminal cover of the Battery Box (see "Opening the UPS and the Battery Box").
Ø
Connect the earth terminals of the UPS and the Battery Box using the yellow/green wire of the cable provided.
Ø
Connect the terminals to the UPS and the Battery Box:
- terminals marked with the + symbol with the red cable
- terminals marked with the N symbol with the blue cable
- terminals marked with the – symbol with the black cable
respecting the correspondence indicated by the symbols print on the terminal cover of the Battery Box and the UPS.
Ø
Reposition the terminal covers removed previously.
CHECKING INSTALLATION:
Ø
Insert the fuses in the SWBATT fuse holders of the Battery Box.
Ø
Close the SWBATT fuse holders of the Battery Box and the UPS.
Ø
Carry out the UPS power-on procedure described in this manual.
Ø
After about 30 sec., check that the UPS is working properly: simulate a black-out by opening the SWIN input isolator of
the UPS. The load must continue to be powered, the "battery power" LED must light up on the control panel of the
UPS, and the latter will emit a beep at regular intervals. When the SWIN input isolator is closed again, the UPS must
resume operation on mains power.
