ing and indication on page 5). An LED holder and a green LED with wire and female
quick connect terminal are provided with the new module for connecting to the
front panel. The vacant hole(s) for the front panel LEDs are closed with plastic plug(s).
Remove the plastic plug from the vacant hole for the LED under the existing bottom
most LED. Insert the LED holder in this hole from the outside. Insert the green LED
from the inside and push it till it locks. Connect the female quick connect terminal of
the LED to the male quick connect terminal marked LED 2 (fig.1). If remote indication
is also required, then connect the female quick connect terminal of the corresponding
colour coded wire for the remote indication connection to the male quick connect
terminal marked LED 1 (fig.1).
6. All the connected modules operate under forced current share control through a
daisy chained share bus formed by interconnecting each module through the male
quick connect terminal marked Jump 1 (fig.1 & 2). A wire with 5 female quick connect
terminals is provided for the above connection. Locate the unused female quick con-
nect terminal(s) of this wire and connect it to the male quick connect terminal marked
Jump 1 (fig.1).
7. use cable ties to secure all loose wiring.
8. As explained under "output Voltage Adjustment" on pages 13-14, the output volt-
age at the individual modules (measured at points S5 & S6 of the module as shown at
fig. 1 on page 21) is required to be set exactly at the same voltage for proper current
share control. Each module is factory preset at a voltage of 14.2V with the help of
potentiometer VR1. Although the optional module SEC-2012MPSB is factory preset at
14.2V, it may differ slightly due to tolerance. It is, therefore, necessary to ensure that
the voltage of all the individual paralleled modules {the existing modules and the
additional optional module(s)} is set exactly at 14.2V. for this, follow instructions given
under "procedure" on page 14.
9. Replace the top cover. Power on the unit and confirm that the "PSM status" LEDs of
all the installed modules are lighted.
Removing A defective module
1. Remove the top cover plate by unscrewing the 10 screws.
2. Locate the defective module. Remove the 6 screws from S1 to S6.
3. Remove the input power supply wires from terminals "l" and "n". Insulate the wire
terminals with insulating tape.
4. Remove connectors from terminals "LED 1 & LED 2" .
5. Remove the "share bus" wire female socket connector from the terminal "Jump
1" and if the defective module is not being replaced immediately and if the unit is
required to be operated without this defective module.
it is mandatory to short the two female sockets on this unused female connector
with a shorting link. (See Fig. 3 ) this will ensure that there is no break in the "share
bus" daisy chain and that all the "Jump 1" terminals are interconnected.
6. The module can now be removed.
