1.
Required method for grounding the radio is to ground the mast to a
ground source. The source and connection points for the building-to-
earth ground in the vicinity of the antenna should be determined.
2.
Also attach an 8 AWG (solid) copper (or equivalent) ground wire to the
m5x.8 grounding stud on the Radio chassis and securely tighten to (15
+/-2in.lbs.) using an 8 mm (5/16 inch) wrench.

Secure the other end of the ground wire to a known earth ground such
as the main ground bar or terminal ground bar of the site. Refer to
local regulations for proper grounding procedures

Available tributary ports may vary depending on the model of KM Series DT or KM Series ST radio.
*”KM Series ST First Release” is a single transceiver variant of KM Series DT. This is offered as the
first release of KM Series ST and has the same features as KM Series ST in a slightly larger housing.
GROUNDING
CAUTION.
IT IS VERY IMPORTANT TO COMPLETE THE GROUND
CABLING PRIOR TO APPLYING ANY DC VOLTAGE TO THE UNIT.
CAUTION.
We strongly recommend that the technical personnel in-
stalling this radio and ancillaries possess the knowledge and skills ap-
propriate for making such installations.
NOTE.
KM Series should be mounted with the Ethernet ports always
facing down.
1.
Attach the KM Series radio, with the radio’s Ether-
net connectors facing down, to the antenna using
the four corner clasps of the radio.
CAUTION.
Proper grounding of the outdoor equipment reduces elec-
tromagnetic interference, provides lightning protection, and protects
against electrical discharge. Using improper techniques in lightning-
prone geographic areas may pose a danger to local personnel.
The source and connection points for the building-to-earth ground
near the antenna location should be determined.

NOTE
. Cable glands are required for external connection of cables to
KM Series.
For the Ethernet cable between KM Series PoE port and the user’s net-
work equipment ensure that the
maximum
POE cable length between
the ODU and such equipment is 100 m (330 ft.). The maximum POE cable
length between the POE injector and the ODU is 80m (260 ft.).
CAUTION
. Any unused port must be sealed with the provided weather-
proof plugs. Dust plugs delivered pre-installed on the units are not
weatherproof and must be discarded before radio field installation.
