Installation Instruction
The Remote Unit, Extension Unit or Master Unit has to be
mounted by proffessionel / special trained installer.
1.1. MECHANICAL INSTALLATION
1.1.1. General
Read the health and safety warnings in chapter 1.3.
1. Warning: Do not install the unit in a way or at a place where the specifications outlined in the
Environmental and Safety Specifications leaflet of the supplier are not met.
2. Warning: It is recommended to use the mounting hardware delivered by the manufacturer
only. If different mounting hardware is used, the specifications for stationary use of the
Remote Unit must not be exceeded.
Note: Exceeding the specified load limits may cause the loss of warranty!
3. Warning: The unit is considerably heavy. Make sure that a suitable mounting surface is used.
Ensure there is adequate manpower to handle the weight of the system.
4. Caution: Due to power dissipation, the Remote Unit may reach a very high temperature.
Ensure sufficient airflow for ventilation.
5. Note: When connecting and mounting the cables (RF, optical, mains, ...) ensure that no water
can penetrate into the unit through these cables.
6. Note: Observe all additional rules or restrictions regarding mounting that apply to specific
Remote Unit types.
If any different or additional mounting material is used, ensure that the mounting remains as safe as the
mounting designed by the manufacturer. Ensure that the static and dynamic strengths are adequate for
the environmental conditions of the site. The mounting itself must not vibrate, swing or move in any
way that might cause damage to the Remote Unit.
Specified torques must be observed for certain mounting procedures according to the following table:

1.2. ELECTRICAL INSTALLATION
1.2.1. General
Read the health and safety warnings in chapter 1.3.
1. Warning: This unit contains dangerous voltages. Loss of life, severe personal injury, or property
damage can be the result if the instructions contained in this manual are not followed.
2. Caution: It is compulsory to ground (earth) the unit before connecting the power supply. A
grounding bolt is provided on the cabinet to connect the ground-bonding cable.
3. Caution: Although the remote unit is internally protected against overvoltage, it is strongly
recommended to ground (earth) the antenna cables close to the antenna connectors of the remote unit
for protection against atmospheric discharge. In areas with strong lightning, it is strongly
recommended to install additional lightning protection.
4. Caution: If the mains connector of the remote unit is not easily accessible, a disconnect device in
the mains power circuit must be provided within easy reach.
5. Caution: Before connecting or disconnecting the mains connector at the remote unit, ensure that
mains power supply is disconnected.
6. Caution: Make sure that an appropriate circuit breaker acting as a disconnect device (as required by
IEC/EN60950-1) and an overcurrent limiting device are connected between mains power and the
Remote Unit.
7. Caution: A connection of the mains supply to a power socket requires the power socket to be nearby
the remote unit.
8. Caution: Incorrectly wired connections can destroy electrical and electronic components.
9. Caution: To avoid corrosion at the connectors caused by electrochemical processes, the material of
the cable connectors must not cause a higher potential difference than 0.6 V (see electrochemical
contact series).
10. Note: Use an appropriate torque wrench for the coupling torque of N-type connectors (2 N-m / 20 in
lb), with 13/16 in opening to tighten the N-type antenna connectors. For example, use torque wrench
of item no. 244379 available from the CommScope e-catalog. Do NOT use your hands or any other
tool (e.g. a pair of pliers)! This might cause damage to the connector and lead to a malfunction of the
Remote Unit.
11. Caution: For unstabilized electric networks, which frequently generate spikes, the use of a voltage
limiting device is advised.
12. Caution: The unit complies with the surge requirement according to EN 61000-4-5 (fine
protection); however, installation of an additional medium (via local supply connection) and/or
coarse protection (external surge protection) is recommended depending on the individual
application in order to avoid damage caused by overcurrent.
13. Caution: Observe the labels on the front panels before connecting or disconnecting any cables.
1.3. HEALTH AND SAFETY WARNINGS
1. Danger: Obey all general and regional installation and safety regulations relating to work on high
voltage installations, as well as regulations covering correct use of tools and personal protective
equipment.
2. Danger: Laser radiation! Do not stare into the beam; do not view it directly or with optical
instruments.
3. Danger: Before opening the unit, disconnect mains power.
4. Danger: Due to power dissipation, the remote unit may reach a very high temperature. Do not
operate this equipment on or close to flammable materials. Use caution when servicing the unit.
5. Warning: Read and obey 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.
6. Warning: It is the responsibility of the network provider to implement prevention measures to avoid
health hazards associated with radiation from the antenna(s) connected to the unit.
7. Warning: Make sure, access is restricted to qualified personnel.
8. Warning: Only licence holders for the respective frequency range are allowed to operate this unit.
9. Warning: Make sure the repeater settings are correct for the intended use (refer to the manufacturer
product information) and regulatory requirements are met.
10. Warning: Use this equipment only for the purpose specified by the manufacturer. Do not carry out
any modifications or fit any spare parts, which are not sold or recommended by the manufacturer.
This could cause fires, electric shock, or other injuries.
11. Warning: 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:
]/[
][
][
2
4cmmW
mW
cm PD
P
D
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
o F (MHz) / 1500 for frequencies from 300MHz to 1500MHz
o 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).
12. Warning: For installations which have to comply with Europe an EN50385 exposure compliance
requirements, the following Power Density limits/guidelines (mW/cm²) according to ICNIRP are
valid:
o 0.2 for frequencies from 10 MHz to 400 MHz
o F (MHz) / 2000 for frequencies from 400 MHz to 2 GHz
o 1 for frequencies from 2 GHz to 300 GHz
13. Caution: Keep operating instructions within easy reach and make them available to all users.
14. Caution: Corresponding local particularities and regulations must be observed. For national
deviations, please refer to the respective documents included in the manual CD that is delivered with
the unit.
15. Caution: Although the remote unit is internally protected against overvoltage, it is strongly
recommended to ground (earth) the antenna cables close to the repeater’s antenna connectors for
protection against atmospheric discharge.
16. Caution: ESD precautions must be observed! Before commencing maintenance work, use the
available grounding (earthing) system to connect ESD protection measures.
17. Note: For a Class A digital device or peripheral:
This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case
the user will be required to correct the interference at his own expense.
18. Note: This unit complies with European standard EN60950.
