Electrical Connections

ATTENTION INSTALLER

All electric wall ovens must be hard wired (direct wired) into an approved junction box. A plug and receptacle is NOT permitted on these products.

DO NOT shorten the flexible conduit. The conduit strain relief clamp must be securely attached to the junction box and the flexible conduit must be securely attached to the clamp. If the flexible conduit will not fit within the clamp, do not install the oven until a clamp of the proper size is obtained.

NOTE TO ELECTRICIAN: The 3 power leads supplied with this appliance are UL recognized for connection to heavier gauge household wiring. The insulation of these 3 leads is rated at temperatures much higher than the temperature rating of household wiring. The current carrying capacity of the conductor is governed by the wire gauge and the temperature rating of the insulation around the wire.

WARNING: Improper

connection of aluminum house wiring to copper leads can

result in an electrical hazard or fire. Use only connectors designed for joining copper to aluminum and follow the manufacturer’s recommended procedure closely.

AVERTISSEMENT :

Le raccordement inadéquat d’un câblage résidentiel en aluminium

àdes fils de sortie en cuivre peut entraîner un risque électrique ou d’incendie. Utilisez uniquement des connecteurs conçus pour raccorder du cuivre à l’aluminium et respectez minutieusement la procédure recommandée par le fabricant.

ZET1, ZET2 specifications

GE ZET1 and ZET2 are advanced digital protection and control relay devices developed by General Electric (GE) for various industrial applications. These high-performance relays are designed to ensure the reliable operation of power systems by offering comprehensive protection for generators, transformers, motors, and transmission lines. Both models are part of GE's commitment to advancing technology in the field of electrical protection, offering enhanced features that prioritize safety and efficiency.

One of the standout features of the GE ZET1 and ZET2 is their modular design. This allows for easy customization and scalability, meaning users can tailor the protection functions to suit specific applications. Both devices support various communication protocols, such as IEC 61850, Modbus, and DNP3, which facilitate seamless integration into smart grid environments and enable effective monitoring and control.

The ZET1 model is particularly known for its compact form factor while still providing robust protection functionality. It includes essential protection elements like overcurrent, earth fault, and differential protection, making it suitable for a variety of low- to medium-voltage applications. The built-in event recording and fault analysis features are significant assets for operators, offering valuable insights into system performance and aiding in fault diagnosis.

On the other hand, the ZET2 model expands on the capabilities of its predecessor by introducing more advanced protection and monitoring functions. It features additional algorithms that can detect not only traditional faults but also numerous abnormal operating conditions. This includes features like voltage and frequency protection, phase failure detection, and harmonic analysis. The ZET2 is particularly well-suited for industrial settings with more complex requirements, ensuring that operators can maintain system integrity under diverse operating conditions.

Both models emphasize user-friendly interfaces, equipped with high-resolution displays for easy navigation and configuration. They also come with intuitive software tools that simplify setup, diagnostics, and maintenance tasks, decreasing downtime and enhancing productivity in environments where every second counts.

In summary, the GE ZET1 and ZET2 relays are engineered for modern power system protection. With their robust features, modular designs, and advanced technologies, they provide essential solutions for safeguarding critical assets in today's fast-paced industrial landscape. These relays stand as a testament to GE's dedication to innovation in electrical protection, ensuring users can operate their facilities with confidence and reliability.
