3. Installation and Setup
This contact block is designed for integration into existing electrical control panels or machinery. Refer to your equipment's primary service manual for specific wiring diagrams and mounting instructions.
3.1. Pre-Installation Check
- Verify that the part number (091-3065) matches the required replacement part.
- Inspect the contact block for any visible damage or defects.
- Ensure all mounting screws are present and in good condition.
3.2. Installation Steps
- Power Disconnection: Turn off and lock out all power sources to the equipment where the contact block will be installed. Confirm zero voltage with a multimeter.
- Remove Old Component: Carefully disconnect wiring from the old contact block, noting wire positions if not clearly marked. Remove the old block from its mounting.
- Mounting: Position the new contact block (091-3065) onto the designated mounting point. Secure it firmly using the provided screws. Do not overtighten.
- Wiring: Connect the electrical wires to the appropriate terminals on the new contact block. Refer to the equipment's wiring diagram for correct terminal assignments (e.g., "3 NO" and "4" for normally open contacts). Ensure connections are secure and free from loose strands.
- Verification: Double-check all connections and mounting security.

4. Operating Instructions
The Switch, Contact Block, Et-Af (Model 091-3065) is a passive electrical component that functions as part of a larger control circuit. It does not have user-operable controls itself. Its operation is dictated by the switch or actuator it is paired with.
- Once installed and wired correctly, the contact block will open or close its electrical circuit based on the mechanical action of the associated switch (e.g., a push-button, selector switch, or limit switch).
- Ensure the associated switch is functioning correctly and is free from obstructions.
- Monitor the equipment for proper operation after installation.

5. Maintenance
The Switch, Contact Block, Et-Af is designed for durability and requires minimal maintenance. However, periodic inspection is recommended to ensure continued reliable operation.
- Visual Inspection: Regularly inspect the contact block for signs of wear, corrosion, or physical damage. Check for loose wiring connections.
- Cleaning: If necessary, gently clean the exterior of the contact block with a dry, lint-free cloth. Do not use solvents or abrasive cleaners. Ensure power is disconnected before cleaning.
- Connection Check: Periodically verify that all electrical connections are tight and secure. Loose connections can lead to overheating or intermittent operation.
Warning: Do not attempt to disassemble the contact block. There are no user-serviceable parts inside.
