Mounting the Amplifier Unit
Mounting on DIN Track
1.
Let the hook on the Amplifier Unit's Fiber Unit
connection side catch the track and push the
unit until it clicks.
Removing from DIN Track
Fiber Unit Connection Side Hook
1.
Push the unit in the direction 1.
2.
Lift it up in the direction 2.
Connectng Amplifier Units with
Communication Units
1.
Mount the Communication Unit and Amplifier Unit
on each DIN track and slide them in the direction of
arrow 1 and insert the connector until it clicks.
2.
Use End Plates (PFP-M: separately sold) at the both
ends of the grouped Amplifier Units to prevent them
from separating due to vibration or other cause.
3. Tighten the screw on the End Plates using a driver.
Up to 30 Amplifier Units can be connected to
E3X-ECT Communication Unit .
Up to 16 Amplifier Units can be connected to
E3X-CRT Communication Unit.
Under environments such as vibration, use an End Plate
even with a single amplifier unit.
Tighten the screw while pressing the End Plate.
1-3 Mounting Fiber Unit
Use Fiber Cutter 2
1.
Insert a Fiber Unit into a fiber cutter hole.
Insert a standard Fiber Unit fiber up to the
position in which it is cut; and
a thin-diameter Fiber Unit fiber to the
bottom of the hole.
Standard Fiber Unit Hole
2.
Press down the blade at a single
