Buzzer 1

The buzzer sounds in the following

situations:

◗ load supplied by Mains 2;

◗ load on battery;

◗ operating problems.

It beeps at a low decibel level and slow

rate for minor problems and when the

load is supplied from battery power.

When the "low battery shutdown

imminent" warning is received, the

beeps

increase in decibel level and rate.

Finally, if the inverter shuts down, the

beep is loud and continuous. A buzzer

reset button is located on the hidden

control panel. If the buzzer is reset, a

higher level alarm will set it on again.

"Load not protected" light

This red light 2 signals that:

◗ the load is supplied by Mains 2

following inverter shutdown (initiated by

the user or by a protective device or a

sudden overload) or the opening of the

inverter output switch Q5N;

◗ battery circuit breaker QF1 has

opened, thus making battery power

unavailable.

Note:

In a parallel system, this light concerns

only the specific UPS. The load may still

be protected by the other lines.

Note:

In parallel systems, this light concerns

only the specific UPS.

The load may not be protected if it

depends on the other lines. It is

necessary to take into account all the

"load protected" lights 5 for the

different system lines or the light on the

control panel of the Static Switch

Cubicle, if it exists.

"Inverter on" button

This green button 6 is used to locally

start the inverter. When it is pushed,

the green "load protected" light 5

blinks for 3 seconds, indicating that the

start-up order has been received. When

the inverter has synchronized with

Mains 2, it supplies the load and the

green "load protected" light 5

remains on. The load is supplied by the

UPS and the system is functioning

normally. If the transfer to Mains 2

conditions are not correct (Mains 2

voltage, frequency or phase conditions

outside tolerances), the inverter will not

start and the system awaits a special

order (see the "Hidden control panel"

section).

Note:

◗ for modular UPSs with external

maintenance bypass or parallel UPSs

with SSC, transfer of the load to the

inverters takes place only when the

number of operating lines required to

supply the load has been reached;

◗ for frequency converters, inverter

start-up must take place with the load

off or drawing a quantity of power equal

to or less than that supplied by a single

UPS.

"Operating problem" light

This orange light 3 signals an

operating problem or an environment

fault, however the load is still supplied

by the inverter.

◗ operating problems:

◗◗ static switch ventilation fault,

◗◗ static switch control system fault;

◗ environment faults:

◗◗ battery temperature outside

tolerances,

◗◗ overload greater than 5%,

◗◗ Mains 2 up but with voltage,

frequency or phase characteristics

outside tolerances with regards to the

inverter.

"Battery operation" light

This blinking orange light 4 signals

that the load is on battery power

following:

◗ a Mains 1 outage or voltage drop;

◗ insufficient power on Mains 1, for

example power supplied by an engine

generator set requiring additional

battery power;

◗ battery problem.

"Load protected" light

This green light 5 signals that the

load is supplied by the inverter and that

the specified battery time is available

in the event of a Mains 1 outage. In

short, it signals that the system is

operating normally.
