Installation Instruction

1.2. ELECTRICAL INSTALLATION
1.2.1. General
Read the health and safety warnings in chapter 1.3 Health and Safety Warnings.
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 power supply connector of the Remote Unit is not easily accessible, a disconnect device in the
power circuit must be provided within easy reach.
5. Before connecting or disconnecting the power supply connector at the Remote Unit, ensure that
power supply is disconnected.
6. Make sure that an appropriate circuit breaker and an overcurrent limiting device are connected
between power supply and Remote Unit.
7. A connection of power supply to a power socket requires the power socket to be nearby the Remote
Unit.
8. Incorrectly wired connections can destroy electrical and electronic components.
9. 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. It is sufficient to tighten the N-antenna connector hand-screwed. Any use of a tool (e.g. pair of
pliers) might cause damage to the connector and thus lead to malfunctioning of the Remote Unit.
11. For unstabilized electric networks which frequently generate spikes, it is advised to use a voltage
limiting device.
12. 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.
13. Observe the labels on the front panels before connecting or disconnecting any cables.
