Improved BTS Site CAPEX and IMPEX

Shelter / equipment room can be

avoided by outdoor BTS

installation. Modular, small and

light BTS minimizes also required

civil work cost

Antenna line civil work and

component cost can be minimized

by locating BTS close to the

antennas (maximizes also cell

capacity)

In indoor installations additional air

conditioning is not needed due to

low power consumption

When handling the modules,

always use the antistatic wrist

strap as shown in the

Connecting the antistatic wrist

must be grounded, otherwise

the antistatic wrist strap will not

work. Refer to Grounding the

(42)

Mounting the stand-alone BTS on the wall

A plinth is required

for mounting the

modules on a wall

Check that the plinth

adapter mechanics

are installed as

instructed in Fixing

adapter mechanics

to plinth section.

(43)

(44)

Mounting the modules on a wall

One mounting plinth per two modules is

installed on a wall. Refer to

Mounting the plinth on a wall for plinth

installation instructions.

(45)

Mounting the stand-alone BTS on the pole

NOTE: There are different

lengths of bolts and places

for bolts in the bracket.

(46)

(47)

Recommended module installation order

• Do not install more than

two modules per plinth

• The modules must be

installed with front panels

facing left or right. Do not

install modules so that the

front panels face up or

down.

(48)

Mounting the modules on the wall or pole

1 Tip

Line up the locating marks in

the module to help aligning

the holes with fixing studs.

Installing optional modules

Flexi power module (FPMA) consists of connector blocks and four slots for

AC/ DC sub-module (FPAA) or battery sub-module (FPBA).

FPMA can include:

. two FPAAs and two FPBAs

. three FPAAs and one FPBA

. one FPAA and three FPBAs

Grounding the BTS

When modules are installed

inside a cabinet, separate

module grounding is not

required.

If the BTS has more than one

plinth (for example in wall or

pole installations), connect the

main ground to one of the

plinths and ground all the

modules to that plinth.
