Warning
These products are intended for use in industrial control systems only.
Do not use these products where voltage, current and temperatures
can exceed those listed under `Technical Data'.
Before using these products for non-industrial applications, life-
support systems, or other applications not within published specifi-
cations, consult NORGREN.
Through misuse, age, or malfunction, components used in control sys-
tems can fail in various modes.
The system designer is warned to consider the failure modes of all
component parts used in control systems and to provide adequate
safeguards to prevent personal injury or damage to equipment in the
event of such failure.
System designers must provide a warning to end users in the
system instructional manual if protection against a failure mode
cannot be adequately provided.
System designers and end users are cautioned to review specific
warnings found in instruction sheets packed and shipped with these
products.
