This connector is different if used with option -J.Refer to Fig. 5.3
for pin arrangements.
¡
When external power source is in the range of 4.5 - 12.5V, cur-
rent limit resistance R is not required. However, when external
power source exceeds 12.5V, current limit resistance R must be
connected.
To calculate the current limit resistance, use the following equa-
tion:
R [
W
] =
Vcc- (1.1+Ri
X
0.005)
0.005
Where ;
Vcc = External Power Source
Ri = The internal resistance (780
W
)
¡
A wrong connection may damage the internal components of the
unit.
¡
Remote ON/OFF circuit (RC (+), RC (-) ) is isolated from input,
output and FG.
¿
-N1
-
A type with a fi tting supporting a dedicated DIN rail.
-
Consult us external view in details.
-
A type in which terminal block screws are aligned vertically (op-
tion: -T).
¿
-W
(It is not possible to combine with option -J)
-
-W is available for detecting low input alarm (PF), detecting low
output voltage (LV) and operating N+1 redundancy.
-
Alarm specifi cation is shown Table 5.2.
-
Special harness is prepared, refer to option parts.
-
Consult us external view in details.
-
Each alarm (PF,LV) is isolated from input, output and FG.

When line voltage is abnor-
mal (low input voltage out of
range), the alarm outputs from
CN3.
If the output voltage drops be-
low the rating, the alarm signal
is output from CN3.
Note :
1
This becomes un-
stable in the event
of output overcur-
rent (intermittent
overcurrent).
2
The alarm signal is
not output for paral-
lel operation that
does not use OR
diodes.
