3) Check the solar panel for any physical damage or obstructions to sunlight.
4) Check the solar panel wiring to ascertain that it is correctly connected to the
5) Disconnect the solar panel from the field device.
6) Set the DMM to 20+ VDC.
7) Determine if the open circuit voltage is greater than or equal to the
8) Using the selected resistor from Table 5–2 for the solar panel wattage,
9) Clip the positive lead of the DMM to the upper side of the test resistor.
10) Clip the negative lead of the DMM to the lower side of the test resistor.
11) Determine if the loaded voltage is greater than or equal to the specification

5.3.5 AC charging system unit test

If the system setup includes an AC charger connected to the 6270 OEU Optional
Equipment Unit and is not supplying the required voltage to the G4 EX unit, the
user may need to test the AC charger.

Sunlight obstructions prevent the solar panel from receiving enough sunlight
to charge the installed battery pack. Clear any debris from the cell face of
the panel.

(see Figure 5–5).
specification listed in Table 5–2 by clipping the positive lead of the DMM to
the first wire and clipping the negative lead of the DMM to the second wire.
If the solar panel is not above the minimum, continue to the next step.

listed in Table 5–2. If the solar panel is not above the minimum, replace the
solar panel, and return to Step 3.
