Guard Against Damage From Electro-Static Discharge; Compliance - CommScope CAP MX Series Installation Manual

Safely Working with ERA Hardware
The CAP MX is to be used only with CommScope (NEC Class 2) or Limited Power Source ERA Subrack, or
equivalent.
Read and observe all the warning labels attached to the unit. Make sure that all warning labels are kept
in a legible condition. Replace any missing or damaged labels.

Guard Against Damage from Electro-Static Discharge

Electro-Static Discharge (ESD) can damage electronic components. To prevent ESD damage, always wear
an ESD wrist strap when working with ERA hardware components. Not all ERA hardware requires
grounding. For those hardware components for which grounding is required, connect the ground wire on
the ESD wrist strap to an earth ground source before touching the component. Wear the wrist strap the
entire time that you work with the hardware.

Compliance

Notice: For installations, which have to comply with FCC RF exposure requirements, the antenna
selection and installation must be completed in a way to ensure compliance with those FCC requirements.
1
Depending on the RF frequency, rated output power, antenna gain, and the loss between the repeater and
antenna, the minimum distance D to be maintained between the antenna location and human beings is
calculated according to this formula:
P

D
[ ] 
 
cm

where
PD
P (mW) is the radiated power at the antenna, i.e. the max. rated repeater output power in addition to
the antenna gain minus the loss between the repeater and the antenna.
•
PD (mW/cm²) is the allowed Power Density limit acc. to 47 CFR 1.1310 (B) for general population /
uncontrolled exposures which is
•
f (MHz) / 1500 for frequencies from 300MHz to 1500MHz
1 for frequencies from 1500MHz to 100,000MHz
–
RF exposure compliance may need to be addressed at the time of licensing, as required by the responsible
–
FCC Bureau(s), including antenna co-location requirements of 1.1307(b)(3).
Notice: For installations which have to comply with European EN50385 exposure compliance
requirements, the following Power Density limits/guidelines (mW/cm²) according to ICNIRP are valid:
2
0.2 for frequencies from 10 MHz to 400 MHz
F (MHz) / 2000 for frequencies from 400 MHz to 2 GHz
•
1 for frequencies from 2 GHz to 300 GHz
•
Notice: Installation of this equipment is in full responsibility of the installer, who has also the
•
responsibility, that cables and couplers are calculated into the maximum gain of the antennas, so that this
3
value, which is filed in the FCC Grant and can be requested from the FCC data base, is not exceeded. The
industrial boosters are shipped only as a naked booster without any installation devices or antennas as it
needs for professional installation.
