2. INSTALLATION

2-1. Unpacking and Initial Inspection

Before you start any action on installing the splitter / combiner, thoroughly read through this

manual. First, carefully inspect the cardboard carton and its content for physical damage. If

damage is noticed, notify your dealer immediately. Delay may infringe carrier's warranty

conditions. Keep all packing for possible future transportation!

2-2. Preparation of the system units

The three amplifiers used with the ACOM3x2000A splitter / combiner should all be of same type

and with same settings, which can affect their gain or voltage selector for instance.

The device is designed to be used with three ACOM2000A automatic amplifiers, but it could be used

also with three

The transceiver used should produce enough power to drive the three amplifiers, i.e. triple the

drive power required by each amplifier for the needed output. Add some overhead due to the

losses in the system. For instance ACOM2000A requires about 60W drive, therefore the

transceiver should be able to put out 200 W for full output.

2-3. Mounting of the rack option

If you use the rack option, be sure to first place an amplifier on the lowest rack level in

the following manner:

Release the two drawer latches on the rear, pull out the drawer, place the amplifier on

it, slide back the drawer and lock the two latches. Afterwards, place the other two

amplifiers in the same way. During an operation, all drawers must be locked and the

wheel brakes engaged.

2-4. Connections

We recommend you use the supplied coaxial cables for the RF connections between the splitter /

combiner and the amplifiers. If you have to use other coaxial cables, please note that the three

coaxial cables going to the amplifier inputs should be the same length, as well as the three coaxial

cables connected to the amplifier outputs. Any difference in lengths would cause a phase

imbalance of the system thus excessive power loss and tripping of the protection circuit.

ACOM1000, ACOM1010 or ACOM1011 manual tune amplifiers.
