Installation Instruction

1.2. ELECTRICAL INSTALLATION
1.2.1. Health and Safety for electrical installation
Read and observe the notices in chapter 1.3 Health and Safety.
1. Danger: Electrical hazard. Danger of death or fatal injury from electrical current. 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.
1.2.2. Property Damage Warnings for electrical installation
1. Attention: 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. Attention: If the mains connector of the Extension Unit is not easily accessible, a
disconnect device in the mains power circuit must be provided within easy reach.
3. Attention: A connection of the mains supply to a power socket requires the power socket
to be nearby the Extension Unit.
4. Attention: Before connecting or disconnecting the mains connector at the Extension Unit,
ensure that mains power supply is disconnected.
5. Attention: 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 Extension Unit.
6. Attention: Incorrectly wired connections can destroy electrical and electronic components.
7. Notice: Although the Extension 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.
8. Notice: 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).
