To change a parameter, enter the correct data and/or click the appropriate check-boxes, then
click SUBMIT to save the change or NO CHANGE to clear and reload the page without saving.
If the data is not entered within 20 seconds after the last keystroke, the data will revert to the
previous value. If the LAN CONFIGURATION password was set, you will be prompted to enter
the password before the changes are accepted.
When SUBMIT is clicked after new IP address information is entered, the front panel LAN indi-
cator blinks rapidly while the unit validates the IP address. If the address is valid, the browser
returns to the INSTRUMENT HOME page (Figure 2-9). If the address entered is already in use,
the following note appears towards the top of the page:
NOTE: IP Address is in use.
Click CONFIGURE LAN and choose another IP to correct.
An IP address that is not already in use must be entered and submitted, otherwise the browser
will lock, requiring the browser to be closed and reopened.
2.8 MULTIPLE UNIT CONFIGURATIONS (MG MODELS ONLY)
Parallel, series and series-parallel configurations of identical BOP MG units increases the rated
voltage and current range of the power supply (BOP ME units do not support multiple unit con-
figurations.) Up to five units can be connected in parallel to increase the current: I
MAX (one unit)
x
N
P
= I
MAX (parallel combination)
where N
P
= number of units in parallel. Similarly, up to three units
can be connected in series to increase the voltage: E
MAX (one unit)
x N
S
= E
MAX (parallel combination)
where N
S
= number of units in series. In addition, identical units may be connected in both
series and parallel. The 2 X 2 configuration, two parallel branches of two series-connected
power supplies, doubles the output voltage and doubles the output current of a single unit. The
3 X 2 configuration, two parallel branches of three series-connected power supplies, triples the
output voltage and doubles the output current of a single unit. Multiple unit configurations
require the appropriate Interconnection Kit (see Table 1-4).
For all multiple unit configurations the master reports the system output parameters: voltage and
current; the slaves report the main channel parameter: voltage for series configurations or cur-
rent for parallel configurations.
Additional hex nuts are provided in the interconnection kit for sufficient cable separation so they
can be oriented as needed to fit onto the terminal.
NOTE: Multiple unit configurations require that all individual units be properly calibrated. (Units
shipped from Kepco have been factory-calibrated.) If not, refer to Section 4 to calibrate
the individual units prior to connecting them in parallel or series. Using calibrated units
ensures that the multiple unit configuration is calibrated; calibrating the multiple unit
configuration is neither needed nor possible.
