4.3. Electrical Installation
4.3.1. Health and Safety for electrical installation
Read and observe the notices in chapter 1.2 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.
4.3.2. 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 Extension 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).
9. Notice: Use an appropriate torque wrench for the coupling torques:
- for N-type connectors (2 N-m / 20 in lb) with 13/16 in opening,
e. g. item no. 244379 available from the CommScope e-catalog
- for 7/16 DIN-type (25 N-m / 19 ft lb) with 1 ¼ in opening,
e. g. item no. 244377 available from the CommScope e-catalog
- for 4.3-10 type connectors (5 N-m, 44 in lb) with 22 mm (7/8) in
opening
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 Extension Unit.
