Description of the interface (protective cap removed):

➀ Adjustment wheel withtwist-lock function.

➁ Downtilt spindle with inte-grated scale.

➀ Thread for fixing of theprotective cap or the RCU(Remote Control Unit).

➁ Gearwheel for RCU-powerdrive.

To set the downtilt angleexactly, you must look hori-zontally at the scale. Thelower edge of the gearwheelmust be used for alignmentpurposes.

Please note: As a result of more stringent legal regulations and judgements regarding product liability, we are obliged to point out certain risks that may arise when products are used under extraordinary operatingconditions.

The mechanical design is based on the environmental conditions as stipulated in ETS 300 019-1-4, whichincludes the static mechanical load imposed on an antenna by wind at maximum velocity.Extraordinary operating conditions, such as heavy icing or exceptional dynamic stress (e.g. strain caused byoscillating support structures), may result in the breakage of an antenna/RCU or even cause it to fall to theground.These facts must be considered during the site planning process.

The installation team must be properly qualified and also be familiar with the relevant national safetyregulations.The details given in our data sheets have to be followed carefully when installing the antennas, RCUsand accessories.The limits for the coupling torque of connectors, recommended by the connector manufacturers mustbe obeyed.

Any previous datasheet issues have now become invalid.

Please note: Separate grounding of the RCU is not needed if the RCU is fixed to an antenna with proper earthing. Please assure that earthing of the antenna has been carried out according to all relevant local regulations.

Instructions for RCU Installation

Attaching the RCU (Remote Control Unit) for remotlely-controlled downtilt adjustment:

Completely remove the pro-tective cap from the antenna.

Check if the phase-shifterfunctions properly over theentire adjustment range bytwisting the adjustmentwheel in such a way thatthe spindle moves comple-tely in and out.

Reset the downtilt to 0 degree.

Completely remove the blackadjustment wheel by simplypulling it downwards.

Connect a control cable to thedaisy chain input of the RCU.

Please note: If the daisychain output is not used,do not remove the daisychain termination.

For the daisy chain solution,remove the daisy chain termi-nation output attaching a con-trol cable to interconnect withthe daisy chain input of thesubsequent RCU.

Please note: Do not removethe daisy chain terminationof last RCU device.

Push the attachment nut ofthe RCU down towards thehousing.

Place the RCU carefully overthe adjustment spindle,observing the correct align-ment of the RCU with regardsto the antenna, i.e. the flatsurfaces of the attachmentfixture on the antenna sideand those inside the RCUhousing must lie flat againsteach other.

Push-up the RCU carefully tothe stop at the antenna.

Please note!Do not twist the RCU in any way during attaching tothe antenna, as this coulddamage the adjustmentspindle.

Tighten the RCU attachmentnut using a torque-wrench;wrench width = 41 mm, min. torque = 15 Nm,max. torque = 18 Nm.

Please note!In cases where a mechani-cal downtilt unit is installed,this downtilt must not beset for a downtilt of morethan 14 degrees.

Connecting the control cables:

Important:To remove the daisy chaintermination, only twist theupper thumb wheel (nearthe RCU).

Important:Do not twist the lowerthumb wheel of the daisychain termination as thismay cause damage to theRCU output socket.
