Grounding the Device
2. Using a CAT-5e cable, connect the PoE injector to the CPE.
3. Using a CAT-5e cable, connect the Ethernet switch to the PoE injector.
CAUTION!
The AC power cable must consist of 3 wires, be minimum 18 AWG, be less than 4.5 m (14.7 ft)
long, and be safety certified according to national rules.
4. Connect the AC open-ended power cable to the Lambda PSU.
Section 2.7
Grounding the Device
When connecting the ground cable to the device, make sure to use a 10 AWG grounding cable and torque the
screw to 15 N·m (11 ft. lb.).
DANGER!
Electrocution hazard – risk of death or serious injury. The system must be properly grounded to protect
against power surges and accumulated static electricity. It is the installer’s responsibility to install this
base station in accordance with the local electrical codes.
Section 2.8
Weatherproofing the Device
Most outdoor CPE, antenna or cable problems are caused by coaxial cable connections loosened by vibration,
allowing moisture to penetrate the connector interface. Siemens strongly recommends weatherproofing
all
outdoor cable connections to prevent the ingress of water and help secure connections.
Since PoE cables also carry DC current, the need for proper weatherproofing cannot be overstated.
Use electrical tape and a heavy-duty weather, abrasion and UV-resistant rubber splicing or self-amalgamating
tape to seal connections.
IMPORTANT!
The warranty is void if the base station is assembled without waterproof sealing or if the sealing is
removed from the connections.
IMPORTANT!
PVC tape, silicon seal and glue are not recommended for weatherproofing, as these materials are
difficult to apply accurately and are difficult to remove.
IMPORTANT!
This method of weatherproofing must be completed on all external connections. If surge arrestors are
used, all associated connections and arrestors must be completely wrapped with splicing tape or self-
amalgamating tape.
Rubber mastic or duct sealing putty must also be used to complete the weatherproofing where needed.
To weatherproof an outdoor cable connection, do the following for both ends of the cable:
1. Make sure the connector and cable are free of any foreign substances, such as oil, grease or dirt.
