Safely Working with ERA Hardware
Guard Against Damage from Electro-Static Discharge
Compliance
1
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.
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:
where
•
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:
•
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
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.
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.
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.
