Connecting the optical microphone
̈ Before connecting the optical microphone, remove the protections caps
from the microphone connections µ and ¸ of the central unit. Keep the
protection caps in a safe place for reuse during transport or storage. They
protect the microphone connections against dirt.
̈ Connect the duplex connector of the professionally ready-made cable to
the microphone connections µ and ¸ of the central unit. Please observe
the correct insertion direction of the connector. The duplex connector is
connected the correct way round when the label ቯ on the connector is
facing downwards as shown.
̈ Connect the fiber optic connector ቨ with the professionally ready-made
cable to the weather and windshield.
Note:
Make sure that at least 15 cm of the fiber optic cable, starting from the
radiation source, is outside the explosion-hazardous area.
Risk of damage to fiber optic cable!
Fiber optic cable must not be bent like conventional cable!
̈ When installing fiber optic cable, make sure not to bend it
beyond a bend radius of 50 mm.
Signal loss!
A wrong polarity will reduce the signal strength.
̈ When connecting the microphone, please observe correct
polarity.
Liquids can damage the electronics!
Liquids entering the housing of the device can cause a short-
circuit and damage the electronics.
̈ For outdoor applications, use only a suitable cable together
with the supplied fiber optic connector ቨ.
