1.2. ELECTRICAL INSTALLATION 1.2.1. General Read the health and safety warnings in chapter 1.3. 1. Warning: 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. Caution: 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. 3. Caution: 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. 4. Caution: 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. 5. Caution: Before connecting or disconnecting the mains connector at the remote unit, ensure that mains power supply is disconnected. 6. Caution: 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. 7. Caution: A connection of the mains supply to a power socket requires the power socket to be nearby the remote unit. 8. Caution: Incorrectly wired connections can destroy electrical and electronic components. 9. Caution: 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. Note: Use an appropriate torque wrench for the coupling torque of N-type connectors (2 N-m / 20 in lb), with 13/16 in opening to tighten the N-type antenna connectors. For example, use torque wrench of item no. 244379 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 Remote Unit. 11. Caution: For unstabilized electric networks, which frequently generate spikes, the use of a voltage limiting device is advised. 12. Caution: The unit complies with the surge requirement according to EN 61000-4-5 (fine protection); however, installation of an additional medium (via local supply connection) and/or
coarse protection (external surge protection) is recommended depending on the individual application in order to avoid damage caused by overcurrent. 13. Caution: Observe the labels on the front panels before connecting or disconnecting any cables.
1.3. HEALTH AND SAFETY WARNINGS 1. Danger: 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. 2. Danger: Laser radiation! Do not stare into the beam; do not view it directly or with optical instruments. 3. Danger: Before opening the unit, disconnect mains power. 4. Danger: Due to power dissipation, the remote unit may reach a very high temperature. Do not operate this equipment on or close to flammable materials. Use caution when servicing the unit. 5. Warning: Read and obey all the warning labels attached to the unit. Make sure that all warning labels are kept in a legible condition. Replace any missing or damaged labels. 6. Warning: It is the responsibility of the network provider to implement prevention measures to avoid health hazards associated with radiation from the antenna(s) connected to the unit. 7.
