Visual check of the connection
Check that all the connections have been made strictly following the indications given in the "Connections" paragraph.
Check that the "1/0" button is in its "0" position (see "Front Views of the UPS" point 5).
Check that all the isolators are open.
Close the battery fuse holders
Close the 4 battery fuse holders (SWBATT) present in the position indicated in the figure below.
WARNING: if a battery expansion (Battery Box) has been installed incorrectly (by not following the
information as provided in the "Connecting the Battery Box to the UPS" paragraph) this can lead to the
battery fuses becoming damaged. If this happens, contact the customer services department immediately to
avoid further damage to the UPS. Note: - When the fuses are closed, small arc flashes may occur due to the
charge of the capacitors present inside the UPS. This is normal and does not cause faults and/or damage.
Power on the UPS
Close the protective devices upstream from the UPS.
Close the input and output isolators
Close all the input (SWIN) and output (SWOUT) isolators except for the maintenance isolator (SWMB), which is to
remain open.
Note:
if the separate bypass option is present, close also the bypass isolator (SWBYP).
