Voltage Check
Once these connections are turned off, verify with a voltmeter that NO voltage is present at the DC+
to DC– terminals. Refer to Figure 34 on page 64.
WARNING: Shock Hazard and Equipment Damage
It may take time for internal capacitance to fully discharge. Ensure full discharge for at least
one minute (less than 1 Vdc) prior to continuing. The inverter’s capacitors may retain a
sizable charge, which can cause electrical shock or severe equipment damage during
normal handling. This damage is not covered under the unit’s warranty.
