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. 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 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:
3.
Exceeding the specified load limits may cause the loss of warranty!
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. Due to power dissipation, the Remote Unit may reach a very high temperature. Ensure
sufficient airflow for ventilation as specified in the individual mounting procedures.
5. When connecting and mounting the cables (RF, optical, mains, ...) ensure no water can
penetrate into the unit through these cables.
6. Also observe all additional rules or restrictions regarding mounting that depend on the type of
Remote Unit. For details refer to chapter 7.2.2 Mechanical Specification. Install the unit
vertically with the fan unit at the top. A maximum tilt angle of 25° from a vertical position
must be kept, as in the following illustrations:
7. A spacing of 40 mm (1.58 inch) around the unit is required.
8. To ensure sufficient airflow when mounting the unit in enclosed spaces, two lid openings (one
for the air inlet and the other for the air outlet) have to be provided. Do not block these air
inlets and outlets when mounting the Remote Unit. The size of each opening must equal at least
17 x 17 cm (290 cm2). Make sure, too, there is no thermal short circuit between the air inlet
and air outlet.
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 have to be observed for certain mounting procedures according to the following table:

 Note:
To avoid damage when mounting the unit, always make sure that the M8 washers
(DIN9021 or DIN125 depending on the mounting kit) are placed behind and in front
of the mounting drillings of the unit.
The mounting procedures for a stand-alone Remote Unit without optional accessories are described and
illustrated in the following sections. For further information regarding special mounting procedures
including mounting of accessory equipment, please see separate manual.
1.2. ELECTRICAL INSTALLATION
1.2.1. General
Read the health and safety warnings in chapter 1.1.
1. 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. It is compulsory to ground the unit before connecting power supply. A grounding bolt is provided on
the cabinet to connect the ground-bonding cable.
3. Although the Remote Unit is internally protected against overvoltage, it is strongly recommended to
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 insert additional
lightning protection.
4. If the mains connector of the Remote Unit is not easily accessible, a disconnect device in the mains
circuit must be provided within easy reach.
5. Before connecting or disconnecting the mains connector at the Remote Unit, ensure that mains
supply is disconnected.
6. Make sure that an appropriate branch circuit breaker and an overcurrent limiting device are
connected between mains and Remote Unit.
7. An external circuit breaker is mandatory as disconnect device. This circuit breaker should be readily
available for the operator.
For the U.S. and Canada, installation has to be done in accordance with the NEC (National
Electronic Code). The external circuit breaker has to be a branch circuit breaker rated 20 A for 110
Vac mains.
8. A field wiring box with conduit must be used for the installation. Use a wire harness rated for AC
mains with at least AWG14 size.
9. A connection of mains supply to a power socket requires the power socket to be nearby the Remote
Unit.
10. Incorrectly wired connections can destroy electrical and electronic components.
11. 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).
12. 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
of 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.
13. For unstabilized electric networks which frequently generate spikes, it is advised to use a voltage
limiting device.
14. The unit complies with the surge requirement according to EN 61000-4-5 (fine protection); however,
it is recommended to install an additional medium (via local supply connection) and/or coarse
protection (external surge protection) depending on the individual application in order to avoid
damage caused by overcurrent.
15. Observe the labels on the front panels before connecting or disconnecting any cables!
1.3. HEALTH AND SAFETY WARNINGS
1. Only suitably qualified personnel is 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. 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.
7. Make sure, access is restricted to qualified personnel.
8. Only licence holders for the respective frequency range are allowed to operate this unit.
9. Corresponding local particularities and regulations must be observed. For national deviations please
refer to the respective documents included in the manual CD delivered.
10. 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. Due to power dissipation, the repeater may reach a very high temperature. Do not operate this
equipment on or close to flammable materials.
12. Before opening the unit, disconnect mains.
13. ESD precautions must be observed! Before commencing maintenance work, use the available
grounding system to connect ESD protection measures.
14. This unit complies with European standard EN60950.
15. Make sure the repeater settings are according to the intended use (see also product information of
manufacturer) and regulatory requirements are met.
16. Although the repeater is internally protected against overvoltage, it is strongly recommended to earth
the antenna cables close to the repeater’s antenna connectors for protection against atmospheric
discharge.
17. Laser radiation! Do not stare into the beam; do not view it directly or with optical instruments.
