About this chapter
This chapter lists warnings and cautions that must be followed when handling the
IED.

Warnings

Do not touch circuitry during operation. Potentially lethal voltages
and currents are present.
Always connect the IED to protective earth, regardless of the
operating conditions. This also applies to special occasions such as
bench testing, demonstrations and off-site configuration. Operating
the IED without proper earthing may damage both IED and
measuring circuitry and may cause injuries in the event of an accident.
Never remove any screw from a powered IED or from a IED
connected to powered circuitry. Potentially lethal voltages and
currents are present.
Always avoid touching the circuitry when the cover is removed.
The product contains electronic circuitries which can be damaged if
exposed to static electricity (ESD). The electronic circuitries also
contain high voltage which is lethal to humans.
