Changing a Power Supply Back To a Standalone

Unit

To release a unit from parallel operation and change it back to a

Standalone unit, do the following:

1. Turn the Power Switch on all parallel units to the OFF position.

2. Disconnect the connections to the positive terminal (labeled

“POS”), negative terminal (labeled “NEG”), and RS485 interface

(labeled “A” and B’).

3. Turn the unit’s Power Switch to the ON position.

4. In the Control Panel menu, scroll to the Parallel Settings

screen

and press Enter

5. Scroll to the Parallel Mode

setting and press Enter. Scroll and

choose Standalone

as the parallel mode setting, then press

Enter

The unit is now configured as a Standalone unit. If the unit was

previously configured as a Slave unit, the System Settings

Control Panel screen will now be unlocked. Note that when the

Parallel Mode

setting (Standalone/Master/Slave) is changed to a

different setting on a unit, the DC Output of that power supply will

automatically be turned OFF if it is currently enabled. The user

will need to verify the output voltage/current settings, then

manually enable the output.

5. TCP/IP WEB BASED UTILITY OPTION

When ordered with the TCP/IP Ethernet option “C”, this power supply

will be equipped with an embedded Web server that allows you to

monitor the status of the power supply, and change the power

supply’s settings and configuration when the unit is powered from the

AC line. (Note: Remote communication is not supported during

battery backup mode when power is being supplied from an external

battery.)

The advantage of an embedded Web server is that it provides an

interface to the power supply that can be accessed through a
