Installation Instruction
1.2. ELECTRICAL INSTALLATION
1.2.1. Health and Safety for Electrical Installation
Read and 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 Remote 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 Remote Unit.
4. Attention: Before connecting or disconnecting the mains connector at the Remote 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 Remote Unit.
6. Attention: Incorrectly wired connections can destroy electrical and electronic components.
7. Notice: Although the Remote 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).
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
- for 4.3-10 type connectors (5 N-m, 44 in lb) with 22mm (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 Remote Unit.
