Note
Regardless of the degree of protection of the casing, the electrical and optical ports are

- damage caused by electrostatic contact discharge when touched
- contamination by dust and fluids
On devices with degree of protection IP65, always close unused ports with the supplied
dust protection caps. Remove these caps only immediately before connecting up the
cables to the ports.
