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 ground, 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 grounding 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.
