Installing a Cabinet

Installing a Cabinet

The procedure for installing cabinets in non-securing mode on concrete floors is the same as that on ESD floors. The installation involves positioning, leveling, combining, and securing cabinets.


The following tools are required:

  • Multimeter
  • Flat-head screwdriver, Phillips screwdriver, and adjustable wrench
  • Measuring tape, marker, powder marker, level, and right angle ruler
  • Ladder

Meters and dedicated tools must be tested and calibrated before being used.


  1. Check the installation environment and materials before installing cabinets.

    1. Check whether the device types and quantity are the same as those described in the packing list.
    2. Check whether the cabinet exterior is in good condition and free of collision and scratch.
    3. Check whether the area, height, and ground bearing capacity of the installation position meet related requirements.

  2. Determine and outline the installation positions.

    1. Check the engineering drawings to determine the positions for installing the cabinets. Align the measuring tape with the upper edge of the installation position, and mark the upper edge by using a marker.
    2. Use the powder marker to outline the positions for installing the cabinets.

      Figure 6-1 shows the outline of the position for installing one cabinet.

      Figure 6-2 shows the outlines of the positions for installing combined cabinets.

  3. Roll the cabinet along its castors to the installation position and position it.

    1. Roll the cabinet to the outlined installation position.
    2. Align the cabinet edges with the outlined lines by using a right angle ruler, as shown in Figure 6-3.
    Figure 6-3 Laying the cabinet in the installation position

    Ensure that the left and right edges of the cabinet and the outer edge of the rear door are aligned with the floor outline when positioning the cabinet by using a right angle ruler.

  4. Secure the cabinet on the floor using the leveling feet.

    1. Open the front and back doors, as shown in step 1 in Figure 6-4.
    2. Rotate the four leveling feet clockwise by using a Phillips screwdriver to lower the leveling feet, as shown in step 2 in Figure 6-4.
    3. Rotate the M12 bolts at the bottom of the leveling feet clockwise by using an adjustable wrench to ensure that the leveling feet contact the ground and the castors hang in the air, as shown in step 3 in Figure 6-4.
      Figure 6-4 Securing a cabinet
      • Spin the castors by using a Phillips screwdriver. If the castors rotate freely, they are hanging in the air.
      • H indicates the height from the cabinet top to the ground. The value of H ranges from 1995 mm to 2005 mm. The height of the leveling feet can be adjustable.
    4. Make sure that the heights measured from the front, rear, right, and left of the cabinet are the same.

  5. Adjust the levelness and verticality of the cabinet by raising or lowering the leveling feet.

    1. Use a level and plumb line respectively to measure the levelness and verticality of the cabinet, as shown in Figure 6-5.
    2. If the cabinet is not level, use an adjustable wrench to raise or lower the leveling feet.
    Figure 6-5 Leveling a cabinet
    • Check the levelness in the front of the cabinet and at the rear of the cabinet.
    • Method of checking levelness: Lay a level. If the bubbles are in the middle of the level when they are static, the position you want to check is level.

  6. Optional: After securing and leveling two or more cabinets, combine the cabinets.

    1. Remove the screws from the connection plates on the front door and back doors using a Phillips screwdriver, as shown in step 1 in Figure 6-6.
      • There are four connecting points on the front door and rear door of the middle cabinets.
      • There are two connecting points on the front door and rear door of the side cabinets.
      • Ensure that the vertical deviation and the distance between cabinets are not greater than 3 mm after the cabinets are combined.
    2. Pass the connection plate through the gap on the cabinet door and secure it using the screws removed in step 1, as shown in step 2 in Figure 6-6.
      Figure 6-6 Combining cabinets
    3. Step 3 in Figure 6-6 shows that the cabinets are combined using connection plates.
