EQUIPMENT MANUAL FOR RF-9122 GSM900-GSM1800 FSR

3.3.5 POLE MOUNTING DETAILS

The equipment can be mounted on customer-located poles of about 75mm in diameter.
Insert and tighten the U bolts to secure the mounting frame onto the pole.
The remainder of the installation is identical to wall-mounting.

3.3.6 DRIP-LOOP

Comba recommends that every horizontal cable entry to the equipment forms a 'U' before it's entry
to the equipment. Any accumulated water on the cable will drip down at the bottom of the loop and
will not climb up to the equipment.

3.3.7 EQUIPMENT CONNECTIONS

The equipment has been designed for all cable entries from the bottom of the chassis. The only
exception is the RS-232 connection where it is a temporary connection for equipment
commissioning.
Ground connection
The chassis must be grounded securely. Connect a copper wire (cross sectional are 16mm
resistance <10 Ω) to the grounding terminal on the equipment chassis, and connect the other end to
a protective ground (i.e. building earth point). An internationally acceptable coloring code of the
ground connection wire is green/yellow.
Service voltage connection
The repeater accepts single phase 220VAC power. The recommended AC connection is rated at
AC220V, 10A and has three connections to include earth. This connection is labeled 'AC in'
