FUNCTIONMODE
The FUNCTION mode changes the output voltage configuration.
Power up all instruments. From the Set screen press the “<more>” soft key and in the
next screen press the “System” soft key.
In the System Parameters Menu, you can use the up or down arrow soft keys to
highlight the FUNCTION parameter.
When the FUNCTION parameter is highlighted, press the “Edit” soft key and use the
“Change” soft key to select the FUNCTION mode to “1Ø3W” .
To save changes made, press the “Enter” soft key and then press the “Exit” soft key
two times to get back to the Set screen.

Once all the linking cables and conductor connections have been made, you can
power up each individual 300XAC via the Power Switch on the front panel. Upon
power up, the 300XAC will go through an initialization screen to verify that the
additional sources are interconnected via the linking cable. If there is a proper
connection, a message will appear acknowledging that additional 300XAC sources
are linked and prompting the user to enable the additional sources.

POLYPHASE OUTPUT MODE (1Ø3W)
In Polyphase Mode, two (2) or three (3) instruments connected together may be used to
increase the total voltage output of the system, or change the output configuration from
1Ø to 3Ø. If two (2) instruments are interconnected 1Ø3W mode is available. This
mode allows the operator to increase the output voltage to up to 600 VAC by configuring
the two sources to output voltage at 180 degrees apart
You will only use one linking cable between the two 300XAC sources. Connect the
linking cable from the output connector labeled “Link Output” of one 300XAC source’s
linking card to the input connector labeled “Link Input” of the second 300XAC source’s
linking card. (See Figure 5)
In the configuration below, the operator must connect the NEUTRALS of both instruments
together and utilize both LINE outputs to achieve full voltage. (See Figure 5)
LINKINGSOURCES
IMPORTANT: BEFORE YOU BEGIN MAKING CONNECTIONS, YOU MUST
ENSURE THAT THE POWER SWITCH ON THE 300XAC INSTRUMENT IS IN THE
OFF POSITION.
