b)        Moisture

maximum operating moisture (humidity)

5. Mechanical Characteristics

The splitter must comply with the IEC 61300 standards, with regard to mechanical strength, such as twisting, vibration, shock, etc.

6. Diagram

A diagram or photo of the unit proposal should be submitted

7. Place of manufacture

Indicate where the proposed device is manufactured, and please mention the quality control methods used

8. Serial number

The splitter must have the serial number printed on the unit itself


Identify the MTBF of the proposed splitter

10. symmetry
