PWE and aviation plug interface waterproof precautions:
1. PWE interface and air plug interface are equipped with dust plugs from the factory. If the
dust plug does not fall off, the protection level of IP64 can be achieved; at the same time,
when the PWE cable and the air plug cable are well connected, IP64 can also be achieved;
2. After the dust plug is removed, the protection level of IP64 cannot be achieved. If it
encounters spraying or flushing at this time, it will cause water to enter the product and affect
the function;
3. Ensure that the water circuit is connected well, and the water pipe interface is tightened
before removing the dust plug to prevent the water pipe from accidentally loosening and
water rushing to the interface, causing the product to enter the water;
4. When adjusting the wiring, remove the dust plug for wiring. It is recommended to keep the
removed dust plug of the PWE interface. Install the dust-proof plug as soon as possible after
the stitches are removed to prevent accidental water ingress in the transfer, water connection
and other links.
