4. セットアップとインストール

The HZC312 auxiliary contact is designed for straightforward installation onto compatible Hager load disconnectors. Ensure the main disconnector is de-energized before proceeding.

4.1 取り付け

1. Identify the designated mounting location on the main load disconnector.
2. Align the HZC312 auxiliary contact with the mounting points.
3. Securely attach the auxiliary contact to the main device according to the disconnector's specific instructions.

4.2 電気接続

The HZC312 utilizes screw terminals for electrical connections.

1. Prepare the wiring by stripping insulation to the appropriate length for the screw terminals.
2. Insert the wires into the designated screw terminals for the 2 NC contacts.
3. Tighten the screws firmly to ensure a secure and reliable electrical connection. Do not overtighten.
4. Verify all connections are correct and secure before re-energizing the system.

5. 操作手順

The HZC312 auxiliary contact operates in conjunction with the main load disconnector to which it is attached. Its contacts change state based on the position of the main disconnector.

• 通常閉（NC）接点： The 2 NC contacts are closed when the main disconnector is in its normal (off or open) position. They will open when the main disconnector is switched to its operating (on or closed) position.
• The auxiliary contacts are used for signaling, interlocking, or control circuits, providing feedback on the status of the main disconnector.

Refer to the instruction manual of the main load disconnector for specific operational details and how the auxiliary contacts integrate into the overall system.

6. メンテナンス

The Hager HZC312 auxiliary contact is designed for minimal maintenance. Regular inspections are recommended to ensure continued reliable operation.

• 目視検査: Periodically inspect the auxiliary contact for any signs of physical damage, discoloration, or loose connections.
• クリーニング： If necessary, gently clean the exterior of the device with a dry, lint-free cloth. Do not use abrasive cleaners or solvents.
• 接続チェック: Ensure all screw terminals remain tight. Re-tighten if any looseness is detected, ensuring power is disconnected first.

No internal user-serviceable parts are present. Do not attempt to disassemble the unit.

7。 トラブルシューティング

If the HZC312 auxiliary contact is not functioning as expected, consider the following common issues:

• 配線ミス: Verify that the auxiliary contacts are wired correctly according to the system's schematic.
• 緩い接続: Check all screw terminals for tightness. Loose connections can lead to intermittent operation or failure.
• ダメージ： Inspect the unit for any visible damage. If damage is present, the unit may need replacement.
• Main Disconnector Issue: Ensure the main load disconnector, to which the HZC312 is attached, is functioning correctly. The auxiliary contact's operation is dependent on the main device.

If problems persist after checking these points, contact qualified electrical personnel or Hager technical support.
