4: Installation
APCD-LM048-1.1 27
WARNING!
The grounding conductor must be attached to the bolt in the
hole marked “GND”.
TIP: As a safety precaution, before attaching the modem to the
pole, use a couple of tie-wraps to secure the Ethernet cable and/
or Ground conductor to the pole to ‘catch’ the modem before it
hits the roof or ground, should you drop it.
Tighten the gear clamps around the pole enough to hold the modem but allowing it to rotate
horizontally. Make the final alignment adjustment so that the modem points in the direction of
the best signal. Usually, there are a range of angles with similar signal levels with the levels
falling off as the modem moves out of that range. Point the modem to the middle of this range.
TIP: You can also mount just the mounting plate and gear
clamps to the pole and then attach the modem to the mounting
plate. However, you need to have a stable position since you will
be holding the modem while threading the mounting plate bolts to
the modem. Again, use a tie-wrap to hold the Ethernet cable to the pole first,
as a safety precaution.
Tighten the gear clamp securely to a torque of 24-30 inch-pounds (2.0 to 2.5 foot-pounds).
Some distortion of the attachment plate is expected as the gear clamps are tightened.
WARNING!
Both gear clamps must be used and must be tightened
securely with a socket or box wrench to the specified torque
.
Ensure that the modem will not rotate around the pole when reasonable force is applied. Avoid
pressing on the radome, push on the cast base instead.
Provide a drip-loop for Ethernet cable and grounding conductor from EUM3006 to pole (see
Figure 5 and Figure 6). This ensures that there is no strain on Ethernet cable as well as
directing any rain drips away from the modem and its cable outlet.
