It is recommended that the user of REL 352 equipment become acquainted with the information in this instruc-
tion leaflet before energizing the system. Failure to do so may result in injury to personnel or damage to the
equipment, and may affect the equipment warranty. If the REL 352 relay system is mounted in a cabinet, the
cabinet must be bolted to the floor, or otherwise secured before REL 352 installation, to prevent the system from
tipping over.
All integrated circuits used on the modules are sensitive to and can be damaged by the discharge of static elec-
tricity. Electrostatic discharge precautions should be observed when handling modules or individual
components.
ABB does not assume liability arising out of the application or use of any product or circuit described herein.
ABB reserves the right to make changes to any products herein to improve reliability, function or design. Spec-
ifications and information herein are subject to change without notice. All possible contingencies which may
arise during installation, operation, or maintenance, and all details and variations of this equipment do not pur-
port to be covered by these instructions. If further information is desired by purchaser regarding a particular in-
stallation, operation or maintenance of equipment, the local ABB representative should be contacted.
