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.
GUID-11CCF92B-E9E7-409C-84D0-DFDEA1DCBE85 v2
The IED with accessories should be mounted in a cubicle in a restricted access area
within a power station, substation or industrial or retail environment.
2.3 Caution signs
IP1503-1 v1
GUID-5D1412B8-8F9D-4D39-B6D1-60FB35797FD0 v2
Whenever changes are made in the IED, measures should be taken to avoid
inadvertent tripping.
