PERATIONS
 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 TRIPOWER X31 HE" 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 TRIPOWER X31 HE" 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 TRIPOWER X31 HE
Close the protective devices upstream from the TRIPOWER X31 HE.
 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).
