Mounting Instructions and Warnings
Remove the AISG control
cables by following the above
Control Cable installation
instructions. Use a TORX T20
Screwdriver to loosen the
retaining screw.
When the retaining screw is
completely released the screw
will hang free but will not fall
from the iRCU housing.
Connect a control cable to the daisy chain input of the iRCU.
The tightening torque for fixing the connector must be 0.5 – 1.0 Nm
(“hand-tightened”).
The connector should be tightened by hand only!
Please note: If the daisy chain output is not used, do not
remove the protection cap.
Carefully slide the iRCU out of
the antenna housing.
Install the new iRCU by sliding
the iRCU into the empty cavity
with the correct orientation.
When the iRCU is inserted all
the way into the antenna hous-
ing use the TORX Screwdriver
to tighten the retaining screw.
Torque: M
A
= 2.5 …. 3.0 Nm.
Reattach the AISG control
cable using the Control Cable
Installation instructions.
Important:
Application of the correct
torque on the screw is
mandatory as earthing of the
iRCU to the reflector screen
is otherwise endangered.
Instructions for iRCU Replacement:
Connecting the control cables:
Warning!
Take care that the iRCU does not fall from the antenna
housing when the retaining screw is not tightened. The falling
iRCU can cause injury or death and may permanently
damage equipment.
For daisy chain operation, remove the protection cap and attach
a control cable to interconnect with the daisy chain input of the
next iRCU.
Please note: Do not remove the protection cap on the daisy
chain output of the last iRCU device.
Caution!
When installing or removing cables, turn only the threaded collar indicated and not the body of the
connector. Rotating the connector body can result in permanent damage to the connector and the
device being installed. Note that the connectors have keyways which must be carefully aligned
before insertion. Insert the connector fully until well seated before tightening.
Hand tighten connectors (0.5 – 1.0 Nm).
Avoid tightening connectors with wrenches or pliers.
Over tightening connectors may permanently damage the iRCU.
