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:
x The connection to the electrical system has been performed by qualified personnel;
x The equipment frame has been correctly grounded to the main earth;
x Make sure that mains input protection cover is removed;
x All the panels removed to allow the UPS connection have been correctly reinstalled;
x The UPS switches Q1 and Q2 are OFF (Pos. 0);
x The battery Breaker Q3 in Battery cabinet in OFF position.
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 started-up can be done on battery supply in case the input mains is
unavailable.
To avoid an incidental battery discharge, it is recommended to do UPS start-up when
input mains is 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:
EXECUTING MAINBOARD

NOTE !
In case the alarm “4410 - Mains bypass out of
tolerance” persists, please contact your Service
Center.
2. Make connection between battery breaker in battery cabinet and battery terminals in UPS in
case of external battery.
