操作说明
以下为设备自带英文操作说明：
A
）
Starting up sequence:
1)
Ensure that
force transfer to bypass switch S4 is at
“
inverter
”
position.
2)
Ensure that Manual
Bypass
Switch is at inverter/Static Bypass position and
Total
Output
Breaker/Switch
is in
“
ON
”
position.
3)
Switch
“
ON
”
Bypass
Breaker/Switch
,
load
gets
connected
to
Bypass
through
Static
Switch
(Not applicable for system without
bypass)
.
4)
Switch
“
ON
”
input
Breaker/Switch
,
dc
voltage
rises
and
inverter
gets
“
ON
”
.O
bserve
output
output
voltage
on
display.
After
synchronization
load
gets
retransferred to
inverter automatically.
5)
Observe
Battery
voltage
on
display,and
then
swtich
“
ON
”
Battery
Breaker/Switch
.
B)
Static bypass
operation:
1)
In
the event of failure of inverter, load gets
transferred to Static Bypass
automatically.
2)
To put load on Static Bypass when
inverter is
“
ON
”
,
change force transfer to
bypass
switch
S4
from
“
inverter
”
to
“
Static
Bypass
”
position,
load
will
get
connected to Static Bypass.
C)
Manual bypass
Operation:
1)
Change
force
transfer
to
Bypass
Switch
S4
from
“
Inverter
”
to
“
Static
Bypass
”
position.
(Not for
applicable for system without bypass).
2)
Switch the
Bypass Switch to Manual Bypass position.
3)
Switch
“
OFF
”
Output
Breaker/Switch.
D)
To shut down
the system:
1)
Switch
“
OFF
”
Output
Breaker/switch
.
2)
Switch
“
OFF
”
Bypass
Breaker/switch
.
3)
Switch
“
OFF
”
Battery
Breaker/switch
.
4)
Switch
“
OFF
”
input
Breaker/switch
.
NOTE:
1.
Press reset switch to reset inverter
fault.
2.
If
system is without Bypass then do not follow bypass
related instructions.
3.
If system is with only manual bypass,
then do not follow static bypass related
instructions.
4.
connect same Bypass Source to UPS for
all parallel & common bus systems.
For
parallel systems operating instrutions will
remains same as above.
Caution :
1.
Do
not
operate
Battery
Breaker/Switch
in
Mains
fail
or
Rectifier
trip
condition.
2.
Do
not
operate
inverter
“
