1.2. ELECTRICAL INSTALLATION
1.2.1. Health and Safety for Electrical Installation
Read and observe observe 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.
Grounding bolts are provided on the cabinet to connect the ground-bonding cable.
2. Attention: If the mains connector of the 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 unit.
4. Attention: Before connecting or disconnecting the mains connector at the 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 unit.
6. Attention: Incorrectly wired connections can destroy electrical and electronic components.
7. Notice: Although the unit is internally protected against overvoltage, it is strongly
recommended to ground (earth) the antenna cables close to the antenna connectors of the
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 ΒΌ in opening,
e. g. item no. 244377 available from the CommScope 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 unit.
10. Notice: For unstabilized electric networks, which frequently generate spikes, the use of a
voltage limiting device is advised.
