Correct clearances must be maintained between SMDCs, SMDC and adjacent structures, and tubing and operating mechanisms. In-sufficient clearances may result in damage to or failure of the SMDC. You must ensure SMDCs are installed with proper clearances as listed below:

1. Minimum required clearance between any supported section of SMDC and the adjacent structure is 1.00 inch.

2. Minimum required clearance between any straight, unsupported section of SMDC and an adjacent structure is 0.25 inch.

3. Minimum required clearance between any two parallel SMDCs is 0.10 inch.

4. Minimum required clearance between any two supported nonparallel SMDCs is 0.10 inch.

5. Minimum required clearance between any two unsupported nonparallel SMDCs is 0.10 inch.

6. Minimum required clearance between any supported section of SMDC and any operating mechanism is 1.00 inch.

Figure 2-21.- SMDC clamp spacing.

7. Minimum required clearance between any unsupported section of SMDC and any operating mechanism is 1.00 inch throughout the full operating range of the mechanism.

8. Minimum required clearance between any supported section of SMDC and an electrical wire bundle is 0.25 inch, if both are clamped in the same vicinity.

9. Minimum required clearance between any unsupported section of SMDC and an electrical wire bundle is 0.25 inch above the wire bundle or 1.00 inch below the wire bundle.
