Resealing the Enclosure

Resealing the Enclosure

Inspect both sides of the gasket and ensure there are no rips or tears. Blow any dust or other

contaminants from each of the surfaces. Replace the gasket back onto the enclosure, around the

battery, aligning the openings of the gasket with the screw bosses; the gasket is reflectively

symmetric, so it does not matter which way around you fit it as long as it aligns with the bosses in

the enclosure.

Check the exposed surface does not have any dust or other contaminants present on it and then

replace the rear half of the enclosure, ensuring that the screw bosses align with the gasket and

front-half of the enclosure. If there is any dust present, it may be blown away, ideally using

compressed air.

Using a

good-quality torque driver

, reseal the enclosure:

Resealing the Enclosure

Replace each of the screws in turn into the openings in the back of the enclosure and tighten

them to a torque of

0.3Nm

(30cNm); take care not to over-tighten them to avoid any damage to

the enclosure.

Once you have tightened all six screws, you may optionally use a set of calipers to verify the

enclosure is providing the correct compression to the gasket:

the overall thickness of the

assembled enclosure should be 14mm (within a tolerance of +/-0.05mm) across the full

length. If any of the areas near a screw are thicker than this, verify the screw at that

position is at the correct torque.
