7.1 PROCEDURES FOR SINGLE LP 33 Series
7.1.1 Start-up of the LP 33 Series
Before connecting hazardous voltages, make sure that:
• The connection to the electrical system has been performed by qualified personnel;
• The equipment frame has been correctly grounded to the main earth;
• Make sure that mains input protection is removed;
• All the panels removed to allow the UPS connection have been correctly reinstalled;
• The UPS switches Q1 and Q2 are OFF (Pos. 0);
• The battery fuses F5, F6, F7 (and eventual external fuses in case of external battery)
are removed.
This procedure must be performed for the first start-up following the installation, with the UPS
completely switched Off and not powered.
This procedure presupposes that the load is not yet supplied by the UPS system.
NOTE !
The UPS can be started-up using the battery supply in case the input mains should be
unavailable.
To avoid an incidental battery discharge, it is recommended to proceed to the UPS
start-up having the input mains available.
1. Switch ON the mains power at the input distribution panel.
As a result the UPS performs a self-test and the LCD will show
the following screen:

SELF TEST OK!
NOTE !
In case the alarm “4410 - Mains bypass out of
tolerance” persists, please contact your Service
Center.
2. Insert the battery fuses F5, F6, F7 and eventual external fuses in case of external battery.
