Short-Circuit Protection
Should a short-circuit occur in the RV, the WF-8700 Series Power Center converter will
drop the voltage output to zero volts. If the short-circuit condition is removed and no
other fault conditions are detected, the converter will resume normal operation. However,
short-circuit conditions are dangerous, and an RV will require inspection by a qualified
service technician.
