Installation Instructions

Pre-Test Checklist

Remove all protective film, if present, and any stickers.

Check to be sure that all wiring is secure and not pinched or in contact with moving parts.

NOTE TO ELECTRICIAN: You must unplug the green wire (near where the long flexible conduit exits the unit) when conducting high-potential testing. Please replug prior to operation.

Check that the bottom trim is installed properly (see page 13).

Check to be sure the mounting screws are installed and flush with the side trim (see page 12).

Operation Checklist

Remove all items from the inside of the oven.

Check that conduit is securely connected to the junction box.

Turn on the power to the oven. (Refer to your Owner’s Manual.) Verify that the bake and broil units, and all cooking functions operate properly.

Check that the circuit breaker is not tripped nor the house fuse blown.

See your Owner’s Manual for troubleshooting list.

If "bAd" "LInE" appears in the display when the power is turned on, the house wiring connections are incorrect.

NOTE TO ELECTRICIAN: The power leads supplied with this appliance are UL recognized for connections to larger gauge household wiring. The insulation of these leads is rated at temperatures much higher than the temperature rating of household wiring. The current carrying capacity of a conductor

is governed by the wire gauge and also the temperature rating of the insulation around the wire.

NOTE: ALUMINUM WIRING

A.WARNING: IMPROPER CONNECTION OF ALUMINUM HOUSE WIRING TO THE COPPER LEADS CAN RESULT IN AN ELECTRICAL HAZARD OR FIRE.

B.Splice copper wires to aluminum wiring using special connectors designed and UL approved for joining copper to aluminum, and follow the manufacturer’s recommended connector procedure closely.

NOTE: Wire used, location and enclosure of splices, etc., must conform to good wiring practice and local codes.

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.
