7.2. Commissioning
After all connections and settings have been done, UPS can be started-up.
7.2.1. Start-Up UPS with Internal Battery
1.
Put the battery fast fuses into the battery circuit breaker on the UPS
(F5)
.
Do not close the circuit
breaker yet!
2.
Switch the bypass circuit breaker on the distribution panel to
“ON”
position.
3.
Switch the mains supply circuit breaker on the distribution panel to
“ON”
position.
4.
Switch the bypass circuit breaker on the UPS
(F4)
to
“ON”
position.
5.
Switch the input circuit breaker on the UPS
(F1)
to
“ON”
position.
6.
Switch the inrush circuit breaker on the UPS
(F6)
to
“ON”
position.
7.
Touch Battery icon to see
Battery / DC
menu measurement. Do not close the battery circuit
breakers
(F5)
until the difference between DC bus and Battery voltages decreases below 10V.
8.
Switch the output circuit breaker on the UPS
(F2)
to
“ON”
position.
9.
Switch the output circuit breaker on the distribution panel to
“ON”
position.
Afterwards UPS starts to supply the loads.
7.2.2. Start-Up UPS with External Battery
1.
Put the battery fast fuses into the battery circuit breaker on the UPS
(F5)
.
Do not close the circuit
breaker yet!
2.
Switch the bypass circuit breaker on the distribution panel to
“ON”
position.
3.
Switch the input circuit breaker on the distribution panel to
“ON”
position.
4.
Switch the bypass circuit breaker on the UPS
(F4)
to
“ON”
position.
5.
Switch the input circuit breaker on the UPS
(F1)
to
“ON”
position.
6.
Switch the inrush circuit breaker on the UPS
(F6)
to
“ON”
position.
7.
Switch the circuit breakers on the external battery cabinet to
“ON”
position.
8.
For the first start up after external battery cabinet installation, you need to check if no polarity
inversion between battery cabinet and UPS. You can control voltages with multimeter on external
battery connection terminals.
9.
Touch Battery icon to see
Battery / DC
menu measurement. Do not close the battery circuit
breakers
(F5)
until the difference between DC bus and Battery voltages decreases below 10V.
10.
Switch the output circuit breaker on the UPS
(F2)
to
“ON”
position.
11.
Switch the output circuit breaker on the distribution panel to
“ON”
position.
Afterwards UPS starts to supply the loads.
Even with no connections have been done, hazardous voltages may exist on connection
terminals and inside the UPS. Do not touch these parts.
If you work on terminals; all circuit breakers in the input/bypass distribution panel, and if any
the battery circuit breakers in the external battery cabinet should be brought to “0” position.
Units with internal batteries have hazardous voltages on the battery connectors even if the
battery circuit breaker is at
“0” position.
Do not touch the battery connectors!
