STRAIN RELIEF
Strain relief clamps are provided on the Express II enclosure to prevent wiring from being
pulled from the circuit board or damaged when passing through the enclosure. To use the strain
relief, thread wires through the clamp and the clear rubber bushing. Position the bushing in
the clamp and tighten the screws on either side so that the wiring does not move. See Figure 9
