GENERAL PRECAUTIONS
In addition to the specific precautions listed throughout this
manual, the following general statements must be observed.
ATTENTION: The SMP-3 overload relay
contains ESD– (electrostatic discharge) sensitive
parts and assemblies. Static control precautions
are required when installing, testing, servicing, or
repairing this assembly. Component damage may
result if ESD control procedures are not followed.
If you are not familiar with static control
procedures, refer to A-B publication 8000–4.5.2,
“Guarding Against Electrostatic Damage,” or any
other applicable ESD protection handbook.
ATTENTION: An incorrectly applied or
installed SMP-3 overload relay can result in
damage to the components or reduction in product
life. Wiring or application errors, such as
incorrectly setting the current to correspond to the
motor full load current rating, incorrect or
inadequate AC supply, or excessive ambient
temperatures may result in malfunction of the
SMP-3 overload relay. Be sure to connect the
green pigtail wire to a solid ground or earth
conductor.
ATTENTION: Only personnel familiar with the
SMP-3 overload relay and associated machinery
should plan to install, start-up, and maintain the
system. Failure to comply may result in personal
injury and/or equipment damage.
