General Precautions If the E300 Electronic Overload Relay is being deployed in an environment with
an ambient temperature greater than 30 °C (86 °F), please refer to the
Environmental Specifications on page 325 for the appropriate temperature
derating. In addition to the specific precautions listed throughout this manual,
the following general statements must be observed.
Base Relay Assembly The following section illustrates the E300 Electronic Overload Relay base relay
assembly instructions.
ATTENTION: The E300 Electronic Overload Relay contains electrostatic
discharge (ESD) sensitive parts and assemblies. Status 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 Allen-Bradley
publication 8000-SB001_-en-p, “Guarding Against Electrostatic Damage”, or
any other applicable ESD protection handbook.
ATTENTION: An incorrectly applied or installed E300 Electronic Overload Relay
can result in damage to the components or reduction in product life. Wiring or
application errors (e.g., incorrectly figuring the FLA setting, supplying incorrect
or inadequate supply voltage, connecting an external supply voltage to the
thermistor terminals, or operating or storing in excessive ambient
temperatures) may result in malfunction of the E300 Electronic Overload Relay.
ATTENTION: Only personnel familiar with the E300 Electronic Overload Relay
and associated machinery should plan to install, start up, and maintain the
system. Failure to comply may result in personal injury or equipment damage.
ATTENTION: The purpose of this user manual is to serve as a guide for proper
installation. The National Electrical Code (NEC) and any other governing
regional or local code will overrule this information. Rockwell Automation
cannot assume responsibility for the compliance or proper installation of the
E300 Electronic Overload Relay or associated equipment. A hazard of personal
injury and/or equipment damage exists if codes are ignored during installation.
ATTENTION: The earth ground terminal of the E300 Electronic Overload Relay
shall be connected to a solid earth ground via a low-impedance connection.
