Mounting Inside Pre-drilled Enclosure

  1. Install wire landing board into appropriate location in an enclosure pre-drilled for the QS-WLB, such as the HQ-LV21-120. Press the snap-in standoffs into the enclosure, beginning with the standoffs on the four corners of the board. A 1/4 in (7 mm) nut driver can be used to help press in the standoffs. Consult the installation instructions for the enclosure to determine the proper location.

Alternate Mounting

The QS-WLB can be mounted in other enclosures that have not been predrilled for the QS-WLB. These enclosures must have a flat mounting surface from 0.050 in (1.3 mm) to 0.062 in (1.6 mm) thick, and must provide at least 0.150 in (3.8 mm) of clearance behind the mounting surface.

  1. Using the template provided (see Figure 1), drill the mounting holes. Using a No. 22 drill bit (0.157 in or 5/32 in (4 mm) diameter), drill the 6 mounting holes as indicated on the template.
  2. Attach the QS-WLB to the enclosure. Press the plastic standoffs into holes drilled in the enclosure. Align and press the QS-WLB onto the standoffs mounted in the enclosure.


1. Connect communications wires. Connect link wiring to the removable terminal blocks, using terminals 1,2,3, and 4 (see Figure 2). Terminal 5 is typically not used–refer to the installation instructions for the device being connected to determine if terminal 5 is to be used. Tighten terminal blocks to 3.5 in·lb to 5 in·lb (0.4 N·m to 0.57 N·m). Do not overtighten.
