SG Frame circuit breakers are listed per Underwriters Laboratories standard UL489 and Canadian Standards Association standard CSA22.2 No.5 and meet the requirements of the International Electrotechnical Commission standard IEC947-2.
WARNING: Danger of electrical shock or injury. Turn OFF the power ahead of equipment before installing this device or removing any other device.
IMPORTANT: Danger d’électrocution. Couper l’alimentation avant d’installer cet appareil ou avant de retirer un autre appareil.
CAUTION: This product is NOT suitable for use in equipment not specifically designed to accept it. Contact the equipment manufacturer for possible equipment modifications.
IMPORTANT: Cet appareil ne doit pas être employé dans un equipement qui n’est pas spécialement adapte a cet effet. Contactez le fabricant concernant les possibles modifications à apporter à l’équipement.
SG 600 amp Frame breaker with microEntelliGuard™ Trip Unit
Assembly
1.Unpack the circuit breaker and inspect it for any shipping damage. Ensure that the breaker has the proper ampere range, sensor rating, voltage rating, and interruption rating for the application. Since this breaker is available in a wide variety of
configurations, compare the catalog number of your purchased breaker with the catalog number key in Table 1. Installation of an incorrect breaker could result in misapplication, lack of system coordination, or reduction in system functionality.

5.Ensure that all terminals are torqued to the proper value, as listed in the lug kit instruction sheet. Install the terminal covers, ensuring that they are firmly seated.
NOTE: Aluminum wire must be used with a joint compound recommended by the wire manufacturer.
IMPORTANT: Si un cable en aluminum est employé, utilisez le lubrifiant recommandé par le fabricant.
WARNING: It is important that the terminal covers are installed correctly to ensure proper circuit breaker operation.
IMPORTANT: Il est important de vérifier que tous couvercles ou caches de protection sont correctement installés afin d’assurer le bon fonctionnement de l’appareil.
6.Finally, connect all associated components that are required for the breaker to function properly, using the instructions supplied with each component.
The following is a list of available associated components:
•Terminal board connector
•Neutral current sensor connector
•Control power connector
•Extension cable
•Control power module (control power transformer may be required)
•Voltage conditioners (potential transformers may be required)
•Voltage module
•Neutral current sensor
Mounting
All Spectra® RMS circuit breakers are suitable for reverse feed and have no line or load markings. Incoming power cables or busbars may be connected to either the upper or lower terminals as required by the application.
WARNING: Danger of electrical shock or injury. Turn OFF the power ahead of equipment before installing this device or removing any other device.
IMPORTANT: Danger de choc électrique ou de blessure. Couper l’alimentation entrant dans l’appareil avant de monter celui-ci ou de démonter d’autres appareils.
