758-916 WLAN ETHERNET Gateway 2.4 GHz

Manual

Version 1.0.1, applicable from HW/SW Version 01/01

2.5

Safety Advice (Precautions)

For installing and operating purposes of the relevant device to your system the

following safety precautions shall be observed:

Always use voltage sources with current limitation/safety extra-low voltage!

Only use power supply sources based on IEC/EN60950 Section 2.5 “Power

sources with limited output” with the device. The output of the external power

supply must be short-circuit protected. The output voltage of the external power

supply shall not exceed 30 VDC.

Do not use device in hazardous environments!

The device is not designed for use in hazardous areas.

Maintenance/Repair only by authorized specialists!

The device contains no parts that can be serviced by users. Always have all

service, reconfiguration, maintenance or repair work performed by specialists

authorized by WAGO.

Do not work on components while energized!

All power sources to the device shall be switched off prior to performing any

installation, repair or maintenance work.

Keep a distance of 20 cm to persons!

Install the device such that it is located at least 20 cm away from all persons

during operation.

Replace defective or damaged devices!

Replace defective or damaged device (e.g., in the event of deformed contacts),

since the long-term functionality of fieldbus station involved can no longer be

ensured.
