2.8. Waterproof Protection on Ethernet Connector of A3-Ei

In order to having better waterproof protection in outdoor environment,

Altai highly recommends to protect the Ethernet connector on A3-Ei

with waterproof tape and electrical tape.

Procedures:

1. Connect the Ethernet cable which is prepared on section 2.5 to A3-

Ei Ethernet connector (see Figure 14).

Figure 14 - Connect Ethernet cable with waterproof plug to A3-Ei

2. Wrap a layer of electrical tape from 2 inches (50mm) below the

edge of the cable connector. Overlap the tape to half-width. The

tape should cover the cable connector body and the cable

connector clamping nut.

The tape can be applied in one or more strips if necessary. A strip

can be coiled onto an applicator such as a pencil. Apply only

enough tension to get good adhesion and keep the tape smooth.

3. Wrap a layer of butyl rubber tape from 1 inch (25mm) below the

edge of the cable connector. Overlap the tape to half-width. Take

extra care to make sure that the cable connector of A3-Ei Ethernet

port junction is tightly sealed. Press the tape edges together so that

there are no gaps. Press the tape against the cable connector

body and the Ethernet port.

4. Wrap a layer of electrical tape from 1 inch (25mm) below the edge

of the cable connector. Overlap the tape to half-width.

Caution: Proper sealing to outdoor connector is recommended. Proper

sealing prevent water ingress to it and protect it from gradual degradation

due to UV radiation and pollution.
