
Connect J1-25 (IPGM) of the Master unit to J1-10 (P) of all Slave
units.

Connect J1-12 (COM) of the Master unit to J1-23 (IPGM_RTN) of all
Slave units.
Single-Wire Method

Set SW1-2 to the DOWN position for the Master unit and UP for all
Slave units.

Connect a wire jumper between J1-8 (LOC/REM) and J1-12 (COM)
for all Slave units.

Connect J1-25 (IPGM) of the Master unit to J1-10 (P) of all Slave
units.
The "Daisy-Chain Connection for Shutoff" is required for Advanced Parallel
operation. These setup connections will shut down all the paralleled power
supplies when a fault condition occurs in any single power supply (See Fig.
6-6).
In Advanced Parallel mode the fault reset function by 'OUT' button & by
RS232 is not activated for Slave units.
2. Connection to the Load
Two-Wire Method
In parallel operation, power supplies can be connected for local or remote
sensing. Refer to Fig. 6-7 and 6-8 for typical connections of parallel power
supplies. The figures show the connections for two (2) units, however the
same connection method applies for up to four (4) units.
With local sensing, it is important to minimize the wire length and
resistance. Also, the positive and negative wire resistance should be as
close as possible to each other to achieve current balance between power
supplies.
Single-Wire Method
In parallel operation, power supplies can be connected for local or remote
sensing. Refer to Fig. 6-9 and 6-10 for typical connections of parallel
power supplies. The figures show the connections for two (2) units,
however the same connection method applies for up to four (4) units.
With local sensing, it is important to minimize the wire length and
resistance. Also, the positive and negative wire resistance should be as
close as possible to each other to achieve current balance between power
supplies.
3. Setting the Units as Master or Slave
a) Depress and hold the FINE button for 3 seconds. The Master/Slave
configuration will be displayed on the Current Display. Rotate the
CURRENT encoder to obtain the desired mode. Refer to Table 6-1 for the
CURRENT display and modes of operation.
b) When the desired configuration is obtained, depress and release the FINE
button or wait approximately 5 seconds.
