M2362-2 v1
Do not touch circuitry during operation. Potentially lethal voltages and
currents are present.
M2364-2 v1
Always use suitable isolated test pins when measuring signals in open
circuitry. Potentially lethal voltages and currents are present.
M2370-2 v1
Never connect or disconnect a wire and/or a connector to or from a IED
during normal operation. Hazardous voltages and currents are present
that may be lethal. Operation may be disrupted and IED and measuring
circuitry may be damaged.
GUID-BEDD698E-356C-4CF9-9DAE-64DB3CEADEAD v1
Dangerous voltages can occur on the connectors, even though the
auxiliary voltage has been disconnected.
M2369-2 v3
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. This is class 1
equipment that shall be grounded.
M2367-2 v1
Never disconnect the secondary connection of current transformer
circuit without short-circuiting the transformer’s secondary winding.
Operating a current transformer with the secondary winding open will
cause a massive potential build-up that may damage the transformer
and may cause injuries to humans.
M2372-2 v1
Never remove any screw from a powered IED or from a IED connected
to powered circuitry. Potentially lethal voltages and currents are
present.
SEMOD168311-3 v1
Take adequate measures to protect the eyes. Never look into the laser
beam.
