8 OPERATION
This symbol refers to the operations of a parallel system.
These steps are not applicable for single units.
8.1 START-UP PROCEDURES
Verify that the input/output connections have been performed by qualified personnel before connecting
mains input voltage and verify that the equipment is correctly grounded.
Only open the front door, do not remove any panels.
Now you can initiate the start-up procedure of the UPS system.
There is no need for any specific knowledge if you carefully follow the step by step instructions given
here, but we recommend that at least the initial procedure should be performed by trained personnel
only.
Check after every step for correct reaction of the UPS, eventually measuring voltages and currents
for confirmation, before you proceed to the next step.
If you encounter any problems following the procedures contained in this section, you should contact
the Service dept of the distributor from whom the equipment was purchased.
There are different start-up procedures, as described on the following pages, depending on the
configuration and the initial state of the UPS system:
•
Initial Start-up of UPS single and parallel system.
This procedure describes how to switch on a single UPS or a complete UPS parallel system.
Initial start-up following the installation means that the load is not being initially supplied and the
system is still completely powered OFF.
•
Start-up single and parallel system following maintenance shut down.
In case of previous maintenance shut down procedure, the load is still powered by the
maintenance switch(es)
Q2
.
This procedure describes how to transfer the load back on to the UPS.
•
Start-up an additional unit in a redundant parallel system.
The load is fully supplied by the other units connected to the parallel bus.
The unit on which we are operating will be connected on the parallel bus bar sharing the load with
each other’s.
WARNING!
Do not allow unattended operation of the inverter with the output switch
Q1
open.
This is an abnormal operating mode and some important protective functions are
disabled!
Do not allow the inverter to continue running after the
“load off”
button is
activated!
