It is compulsory to ground the UPS according to the Safety Standards.
To guarantee safety it is necessary to be sure that the local electric plant is supplied
with GROUND (in compliance with the Safety Standards), and that a valid connection is
guaranteed between the GROUND of the UPS and the GROUND of the local electric
plant, through the Input/Output cables, as explained in this section.
Any interruption of the GROUND conductor is absolutely prohibited.
We recommend to use dedicate Input/Bypass/Output power Lines for the UPS.
Risk of electric shock at the Output lines if the UPS is ON, even when the UPS is not
connected to AC utility line.
Risk of electric shock at the Output lines while the unit is connected to the AC utility
line.
Risk of electric shock: do not remove the cover. The UPS contains internal parts, which
are at a high Voltage and are potentially dangerous, capable of causing injury or death
by electric shock.
There are no internal parts in the UPS, which are user serviceable. Any repair or
maintenance work must be performed exclusively by qualified technical personnel
authorized by TECNOWARE. TECNOWARE declines any responsibility if this warning is
disregarded.
Disregard for these warnings may lead to a risk of electric shock to operators.
Do not start the UPS until the installation is completed.
Make sure the wiring is correct and the power cables are fixed firmly (refer to chapter
10.3 “Wiring” for details).
Make sure the Power Modules ID has been correctly configured for each Power Module.
Make sure the Ready Switch on each Power Module has been moved to the “Locked”
position.
Make sure all the Breakers are switched OFF.
11.1 AC Startup
Use the following procedures when turning ON the UPS from a fully powered-down state:
1. ONLY IF THERE IS AN EXTERNAL BATTERY BOX: switch ON the Battery Breaker of Battery Box.
2. Switch ON the Battery Breaker on the rear side, if it is present.
3. Switch ON the external Input Breaker to connect the Main AC Input Line to the UPS. The Static Transfer
Switch (STS) Module starts running and the Control Panel lights up (see Figure 11.1).
