ISOLATION TRANSFORMER OPERATION LIGHT STATUS
THERMAL PROTECTION
The optional IsoBoost unit is outfi tted with a built in
thermostat (temperature switch) that is sunk into the
transformer windings. When a sustained overload or
overheating occurs the switch kicks in to shut down the
unit. When this happens, the power to the unit shuts
down, status lights will be "Off " and there will be no
output power from the unit. Allow the unit to cool down
which may take up to 1 hour. At some point the tem-
perature switch will reset and the unit will resume normal
operation.
