WARNING! Shock hazard – The ArcticStep panel heater can store a charge. Take care to fully discharge
the heater prior to disconnecting the megger.
Turning off the power and setting the voltage selector switch to zero discharges most megger. Some megger
have a separate discharge mode.
WARNING! Fire hazard in hazardous locations megger tests can produce sparks. Be sure there are no
combustible gases or vapours in the area and obtain a hot work permit (if required) before performing this
test. Refer to site procedures for requirements regarding electrical tests in hazardous locations.
