CAUTION Make sure that the connection between –V terminals is reliable to avoid disconnection
during operation. Disconnection may cause damage to the power supply.

NOTE

With local sensing it is important to minimize the wire length and resistance. Also the positive and
negative wire resistance should be close as possible to each other to achieve current balance be-
tween power supplies

*OVP to its maximum value
*AST On
*OUT On
*Foldback protection Off

c) The Master and Slave modes are stored in the power supply EEPROM when the AC power is turned
off. The system will return to the Master/Slave mode upon re-application of AC power.
5. CURRENT display accuracy
In the advanced parallel mode, the Master unit calculates the total current by multiplying the Master output
current by the number of Slave units. In this method, the CURRENT display accuracy is 2% +/- 1 count. In
cases that higher accuracy is required, it is recommended to use the basic parallel operation mode.
6. To release units from Slave mode
Slave units can be released using the following procedure:
a) Depress FINE button for 3 seconds. The Master/Slave configuration will be displayed on the
CURRENT display.
b) Select H1 mode using the CURRENT encoder.
c) Depress FINE button again or wait 5 seconds.
d) Turn the AC power Off to store the new setting.
e) After exiting from Slave operation the unit’s parameters will be set to:

*Programmed Voltage to zero
*Programmed Current to zero
*UVL to zero volts
*OVP to its maximum value
*AST OFF
*OUT OFF
*Foldback protection OFF
*Locked Front Panel
