4. Opsætning og installation

Installation of the QMB320EX extension assembly requires adherence to specific electrical and mechanical procedures. It is imperative that installation is performed by a certified electrician or qualified personnel.

4.1 Kontrol før installation

• Verify that the QMB320EX assembly is compatible with the existing panelboard.
• Inspect all components for any signs of damage. Do not install damaged parts.
• Ensure all necessary tools and additional hardware (if required) are available.

4.2 Installationsprocedure (generelle trin)

1. De-energize Panelboard: Turn off and lock out all power sources to the panelboard where the extension will be installed. Verify zero voltage with a suitable meter.
2. Forbered monteringsområde: Identify the designated area on the panelboard for the extension. Remove any covers or obstructions as necessary.
3. Monteringsbeslag: Securely attach the extension mounting brackets (e.g., the L-shaped bracket and rectangular plate shown in Figure 1) to the panelboard structure using appropriate fasteners. Ensure they are level and aligned.
4. Connect Extension: Integrate the extension assembly with the existing panelboard bus structure or frame as per specific QMB panelboard instructions. This may involve mechanical and electrical connections.
5. Sikre komponenter: Ensure all components of the extension assembly are firmly secured and all electrical connections are properly torqued to manufacturer specifications.
6. Re-install Covers: Replace any removed covers or barriers, ensuring proper enclosure integrity.
7. Prøve: After installation, carefully re-energize the panelboard and perform functional tests as required by local codes and manufacturer guidelines.

5. Funktion og betjening

The QMB320EX Panelboard Qmb Extension Assembly functions as a structural and electrical expansion for a QMB panelboard. Once correctly installed, it provides the necessary framework and connection points to add additional QMB switches, circuit breakers, or other compatible devices, thereby increasing the panelboard's capacity or modifying its configuration. It does not have user-operable controls; its operation is passive, facilitating the function of other installed components.

6. Vedligeholdelse

The QMB320EX extension assembly itself requires minimal maintenance once properly installed. However, it is part of a larger electrical system that requires periodic inspection.

• Årlig inspektion: Have a qualified electrician inspect the panelboard and all its components, including the extension assembly, annually.
• Tjek forbindelser: During inspections, verify that all mechanical and electrical connections remain tight and free from corrosion.
• Renhed: Ensure the interior of the panelboard remains clean and free of dust, debris, or moisture.
• Skadevurdering: Look for any signs of physical damage, discoloration, or overheating on any part of the assembly.

7. Fejlfinding

As a passive extension component, the QMB320EX assembly typically does not "malfunction" in the traditional sense. Issues are usually related to improper installation or external factors affecting the entire panelboard.

• Løse forbindelser: If issues arise with devices connected to the extension, first check for loose mechanical or electrical connections within the extension assembly and the devices themselves.
• Fysisk skade: Inspect the assembly for any visible damage, bends, or breaks that might compromise its structural integrity or electrical continuity.
• Overophedning: Discoloration or signs of heat on the assembly or connected components may indicate an overload or poor connection. Immediately de-energize and investigate.
• Professionel assistance: For any persistent issues or concerns regarding the panelboard or its extension, contact a qualified electrician. Do not attempt repairs if you are not qualified.
