GROUND THE UNIT

WARNING! This unit must always be grounded. Consult an

appropriate electrical inspection authority or an electrician if

you are uncertain that suitable grounding is available.

DO NOT CONNECT POWER BEFORE GROUNDING!

Step 1.

Connect the supplied copper wire (CSA 16 mm

GND cable to the GND connector and the

equipment rack or building earth. See Figure 10.

Step 2.

Ground the unit by connecting the "earth wire"

of the power cord to the ground terminal of the

AC supply.

Step 3.

For installations with GX external combiner –

connect the grounding wire supplied with the

external combiner to the earth ground and to

the combiners' grounding lug (see Figure 9).

RF CONNECTIONS

CAUTION! Any open RF port on GX or improper connection

between GX RF ports and combiner inputs, will damage GX

internal power amplifier after the equipment is powered on.

Make sure all connections are performed correctly before

powering.

For direct connections to DAS antennas:

Step 1.

Using the required coax cables, connect the GX

RF ports to the service antennas.

Step 2.

Ensure lightning protection for each antenna port.

Step 3.

Waterproof all RF ports (recommended drip loops).

Step 4.

Terminate any unused GX and RF ports.

For connections via GX 2x1 external combiner

(P/N: AK-GX-LH-COMB):

Step 1.

Using DIN cables (provided with external

combiner), connect the RF output to one of the

external combiner input ports.

Note:

MIMO units required two 2x1 external combiners

(one for each RF antenna output port).

Step 2.

Ensure lightning protection for each antenna port.

Step 3.

Waterproof all RF ports.

Step 4.

Terminate any unused GX RF ports.

Step 5.

Connect external combiner output connector to

broadband antenna. Refer to Figure 12.
