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 section 1.3.
1. 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. It is strongly recommended to install the unit vertically.
3. When mounting the Remote Unit, the connector flange with the cables must point to the
ground. A maximum tilt angle of 25° to the horizontal position of the connector flange must be
kept in each mounting direction. If a different installation of the Remote Unit is required,
please contact customer service for further information.
4. It is recommended only to use the mounting hardware delivered by the supplier. 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!
5. 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.
6. Due to power dissipation, the Remote Unit may reach a very high temperature. Ensure
sufficient airflow for ventilation. A minimum distance of 300 mm to ceiling, floor, etc. must be
maintained above and below the unit. Also, observe the instructions in the individual mounting
procedures
7. For outdoor installations, the pre-mounted front cover must be installed.
8. For indoor installations where the ambient temperature can reach above 40°C, the cover must
be removed.
9. When connecting and mounting the cables (RF, optical, mains, ...) ensure no water can
penetrate into the unit through these cables.
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.
1.2. ELECTRICAL INSTALLATION
1.2.1. General
Read the health and safety warnings in section 1.3.
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.
1. 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.
2. 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.
3. 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.
4. Before connecting or disconnecting the mains connector at the Remote Unit, ensure that mains
power supply is disconnected.
5. 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.
6. A connection of the mains supply to a power socket requires the power socket to be nearby the
Remote Unit.
7. Incorrectly wired connections can destroy electrical and electronic components.
8. 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).
9. Use an appropriate torque wrench for the coupling torque (25 N-m / 19 ft lb) of 7/16-DIN connectors
with 1 ¼-inch opening to tighten the 7/16-type antenna connectors. For example, use torque wrench
item no. 244377 available from the Andrew 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.
10. For unstabilized electric networks, which frequently generate spikes, the use of a voltage limiting
device is advised.
11. 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.
12. Observe the labels on the front panels before connecting or disconnecting any cables.
1.3. HEALTH AND SAFETY WARNINGS
1. Only suitably qualified personnel are allowed to work on this unit and only after becoming familiar
with all safety notices, installation, operation and maintenance procedures contained in this manual.
2. Read and obey all the warning labels attached to the unit. Make sure that the warning labels are kept
in a legible condition and replace any missing or damaged labels.
3. 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.
4. Keep operating instructions within easy reach and make them available to all users.
5. It is the responsibility of the network provider to implement prevention measures to avoid health
hazards which may be associated to radiation from the antenna(s) connected to the unit.
6. Laser radiation! Do not stare into the beam; do not view it directly or with optical instruments.
7. 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:
]/[

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).
