ADJUSTING GROUNDING RESISTANCE FOR POSITIVE OR NEGATIVE POLE
GROUNDING (options +F282 and +F283)
By default, the grounding resistance is set to 3 kohm. If needed,
modify the resistor configuration on the PGND-02 (A20) board as
follows:
• WARNING! Make sure that the voltage is disconnected and
the DC main switch (Q2) is open.
• Remove the shroud protecting the board.
• Rewire the jumper wires on terminals X4 and X5.
PARAMETER SETTINGS BEFORE FIRST START
Make the parameter settings needed before the first start
according to the firmware manual.
See the start-up section in the
firmware manual.
FIRST START (local control mode)
Measure and record the DC voltage from the solar generator.
-100kW un
its with optional miniature circuit breakers (+H377):
Open the miniature circuit breakers. Measure and record all DC
inputs.
Note: The expected and measured
DC voltages should be roughly
equal.
-100kW units
with optional miniature circuit breakers (+H377):
Close the miniature circuit breakers.
Close the AC and DC main switches.
Switch on the auxiliary power. The control boards and the
CDP312R control panel should
“wake up”. The inverter is in the
stand-by mode if no faults are active.
This is indicated by the STAND BY
text on the control panel. For
descriptions of the inverter modes,
refer to the firmware manual.
Note: There may be fault and
warning indications flashing on the
display. They will be reset during the
next steps.
Ensure that the control panel is controlling the master control unit
(A43) by checking the node number from the display.
See the firmware manual.
Units with optional emergency stop function (+Q951):
Release
the emergency stop button and reset the emergency stop circuit.
Units with optional positive/negative grounding (+F282/+F283):
Configure the grounding option.
See the firmware manual.
Reset all faults on both control boards. See the firmware manual.
Check that the DC voltage of the solar generator matches the
value of 01.34 PV MODULE DC MEAS in the Master control
program.
Note: If the DC voltage differs from
the parameter value, do not try to
start the inverter. Contact ABB.
