Getting Started
4. Check whether the power voltage matches with the supply voltage. Please
refer to 2.4 Connecting the Power Cord to select proper AC input.
5. After multiple units are connected in parallel and powered on, the error re-
lated to the fiber-optic is indicated. Please refer to the following steps for
troubleshooting.
• FIBER MULTI MASTER: Multiple units (with panel) are connected in par-
allel, please confirm whether multiple Masters are set. Select System→-
Parallel menu to reset. There can only be one single unit as the Master,
and the other single units must be set to Slave. After the setting is com-
pleted, power off and restart each single unit.
• FIBER EXT UNLOCK: Multiple units (with panel) are connected in paral-
lel, check whether the cable connection of the fiber outer ring (TX and
RX) is closed. Then confirm that whether the System→Parallel menu is
set. There can only be one single unit as the Master, and the other single
units must be set to Slave. After the setting is completed, power off and
restart each single unit.
• FIBER INNER UNLOCK: Only one master unit (with panel) and the rest
is slave unit (without panel) connected in parallel, firstly, confirm whether
the cable connection of the fiber inner ring (F-TX and F-RX) is closed.
Then confirm that whether the System→Parallel menu is set. If yes,
please restore the setting to Single mode, then power off and restart.
Then consult ITECH technical support engineers for the parallel setting
method in this case.
6. If the instrument still does not start, contact ITECH technical support
engineer.
3.2 Source Mode/ Load Mode Switch
The IT6000B series Regenerative Power System can be used as a bidirectional
power supply or a load, which can be switched by [Source] and [Load] on the
front panel.
Source Mode
The default mode when the instrument is powered on (To switch Load Mode to
Source Mode, press [Source]), indicating that the instrument serves as a bidir-
ectional power supply. The instrument can output power at the maximum rated
power indicated in the instrument specification. It can also absorb electric en-
ergy at the maximum rated power and convert electric energy into current,
which is returned back to the grid.
