General Precautions
If the E300 relay is being deployed in an environment with an ambient
temperature greater than 30 °C (86 °F), see the Environmental Specifications on
page 626 for the appropriate temperature derating. In addition to the specific
precautions listed throughout this manual, the following general statements must
be observed.
To reduce electrical noise interference between the E300 relay and a contactor,
you should use an RC surge suppressor on AC-based contactor coils. For Allen-
Bradley® contactors, use the following RC surge suppressors.
Table 1 - Recommended Surge Suppressors
Contactor Type Surge Suppressor Cat. No.
Bul. 100-C IEC Contactors 100-FSC280
Bul. 300 NEMA Contactors 100-FSC280
Bul. 500 NEMA Contactors 199-FSMA1
ATTENTION: The E300 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, see 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 relay can result in damage
to the components or reduction in product life. Wiring or application errors (for
example, incorrectly calculating 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 relay.
ATTENTION: Only personnel familiar with the E300 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 overrules this information. Rockwell Automation cannot
assume responsibility for the compliance or proper installation of the E300 relay
or associated equipment. A hazard of personal injury and/or equipment
damage exists if codes are ignored during installation.
