SEL-734W and SEL Wireless Current SensorInstruction Manual Preface
Overview
The SEL-734W Capacitor Bank Control is based on the SEL-734 Advanced
Metering System platform. Devices ship with an outdoor-rated enclosure and are
programmed with control strategies via SEL design templates.
The SEL-734W Field Reference Guide provides a general overview of the
SEL-734W and describes the procedures for installation as a capacitor bank con-
trol. This guide also provides troubleshooting and testing methods.
The SEL-734W Data Sheet describes the SEL-734W and SEL-WCS system, the
features and control strategies of the SEL-734W, as well as interface.
The SEL-734W ACSELERATOR QuickSet Design Template Guide describes the
operation, details the settings, and contains logical diagrams for developers.
The SEL-734 Instruction Manual details all other features available in the
SEL-734 device, including metering, power quality, and communications.

General Safety Marks
CAUTION
There is danger of explosion if the battery is incorrectly replaced.
Replace only with Rayovac no. BR2335 or equivalent recommended by
manufacturer. See Owner's Manual for safety instructions. The battery
used in this device may present a fire or chemical burn hazard if mis-
treated. Do not recharge, disassemble, heat above 100°C or incinerate.
Dispose of used batteries according to the manufacturer’s instructions.
Keep battery out of reach of children.
ATTENTION
Une pile remplacée incorrectement pose des risques d’explosion. Rem-
placez seulement avec un Rayovac no BR2335 ou un produit équivalent
recommandé par le fabricant. Voir le guide d’utilisateur pour les instruc-
tions de sécurité. La pile utilisée dans cet appareil peut présenter un
risque d’incendie ou de brûlure chimique si vous en faites mauvais
usage. Ne pas recharger, démonter, chauffer à plus de 100°C ou inciné-
rer. Éliminez les vieilles piles suivant les instructions du fabricant. Gardez
la pile hors de la portée des enfants.
