How to to wiring operation?
1. do wire stripped about 8mm;
2. turn off components orderly: waterproof nut, cable gland, enclosure;
3. insert the wire through components orderly to the terminals;
4. using a fine screwdriver to tighten up these screws on terminals;
5. assmble all the components tightly;
6. male plug to female socket. That is ready.

How to choose a right cable gland to get better waterproof grade?
The cable gland inner diameter should be closer to but larger than cable OD to ensure the cable go through cable gland but get better waterproof effect.
Below datas just for reference:
1. OD6-7mm, φ7mm;
2. OD7-9mm, φ9mm;
3. OD9-10mm, φ10mm;
4. OD10-11mm, φ12mm;
5. OD11-13mm, φ13mm;
Here is the irregular pin connector of Model M25. This is new model that is no need adding with glue.
