4.2. ELECTRICAL INSTALLATION
4.2.1. General
Read the health and safety warnings in chapter 1.2 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.
3. Although the remote unit is internally protected against over-voltage, 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 highly 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 circuit breaker and an over-current limiting device
are connected between mains and remote unit.
7. A connection of mains 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 N-antenna connectors 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 over-current.
13. Observe the labels on the front panels before connecting or disconnecting any
cables.
14. Observe that the cable-cross section is 3 x 1.5 mm
2
for the voltage feed and
4 mm
2
for the grounding bolt.
